# Dublin

yup the Gerry Hutch

## Etymology

The name Dublin comes from the Middle Irish word Du(i)blind (literally "Blackpool"), from dubh "black, dark" and linn "pool". This evolved into the Early Modern Irish form Du(i)bhlinn, which was pronounced "Duílinn" in the local dialect. The name refers to a dark tidal pool on the site of the castle gardens at the rear of Dublin Castle, where the River Poddle entered the Liffey.
The Middle Irish pronunciation is preserved in the names for the city in other languages such as Old English Difelin, Old Norse Dyflin, modern Icelandic Dyflinn and modern Manx Divlyn as well as Welsh Dulyn and Breton Dulenn. Other localities in Ireland also bear the name Duibhlinn, variously anglicised as Devlin, Divlin and Difflin. Variations on the name are also found in traditionally Gaelic-speaking areas of Scotland (Gàidhealtachd, cognate with Irish Gaeltacht), such as An Linne Dhubh ("the black pool"), which is part of Loch Linnhe.
It is now thought that the Viking settlement was preceded by a Christian ecclesiastical settlement known as Duibhlinn, from which Dyflin took its name. Beginning in the 9th and 10th centuries, there were two settlements where the modern city stands. The Viking settlement of about 841, Dyflin, and a Gaelic settlement, Áth Cliath ("ford of hurdles") further up the river, at the present-day Father Mathew Bridge (also known as Dublin Bridge), at the bottom of Church Street.
Baile Átha Cliath, meaning "town of the hurdled ford", is the common name for the city in Modern Irish, which is often contracted to Bleá Cliath or Blea Cliath when spoken. Áth Cliath is a place name referring to a fording point of the River Liffey near Father Mathew Bridge. Baile Átha Cliath was an early Christian monastery, believed to have been in the area of Aungier Street, currently occupied by Whitefriar Street Carmelite Church. There are other towns of the same name, such as Àth Cliath in East Ayrshire, Scotland, which is anglicised as Hurlford.

## History

The area of Dublin Bay has been inhabited by humans since prehistoric times; fish traps discovered from excavations during the construction of the Convention Centre Dublin indicate human habitation as far back as 6,000 years ago. Further traps were discovered closer to the old settlement of the city of Dublin on the south quays near St. James's Gate which also indicate mesolithic human activity.
Ptolemy's map of Ireland, of about 140 AD, provides possibly the earliest reference to a settlement near Dublin. Ptolemy, the Greco-Roman astronomer and cartographer, called it Eblana polis (Ancient Greek: Ἔβλανα πόλις).
Dublin celebrated its 'official' millennium in 1988, meaning the Irish government recognised 988 as the year in which the city was settled and that this first settlement would later become the city of Dublin.
It is now thought the Viking settlement of about 841 was preceded by a Christian ecclesiastical settlement known as Duibhlinn, from which Dyflin took its name. Evidence indicating that Anglo-Saxons occupied Dublin before the Vikings arrived in 841 has been found in an archaeological dig in Temple Bar.
Beginning in the 9th and 10th centuries, there were two settlements which later became modern Dublin. The subsequent Scandinavian settlement centred on the River Poddle, a tributary of the Liffey in an area now known as Wood Quay. The Dubhlinn was a pool on the lowest stretch of the Poddle, where ships used to moor. This pool was finally fully infilled during the early 18th century, as the city grew. The Dubhlinn lay where the Castle Garden is now located, opposite the Chester Beatty Library within Dublin Castle. Táin Bó Cuailgne ("The Cattle Raid of Cooley") refers to Dublind rissa ratter Áth Cliath, meaning "Dublin, which is called Ath Cliath".

### Middle Ages

In 841, the Vikings established a fortified base in Dublin. The town grew into a substantial commercial center under Olaf Guthfrithson in the mid-to-late 10th century and, despite a number of attacks by the native Irish, it remained largely under Viking control until the Norman invasion of Ireland was launched from Wales in 1169. The hinterland of Dublin in the Norse period was named in Old Norse: Dyflinnar skíði, lit. 'Dublinshire'.$^{:24}$ It was upon the death of Muirchertach Mac Lochlainn in early 1166 that Ruaidrí Ua Conchobair, King of Connacht, proceeded to Dublin and was inaugurated King of Ireland without opposition.
According to some historians, part of the city's early economic growth is attributed to a trade in slaves. Slavery in Ireland and Dublin reached its pinnacle in the 9th and 10th centuries. Prisoners from slave raids and kidnappings, which captured men, women and children, brought revenue to the Gaelic Irish Sea raiders, as well as to the Vikings who had initiated the practice. The victims came from Wales, England, Normandy and beyond.
The King of Leinster, Diarmait Mac Murchada, after his exile by Ruaidhrí, enlisted the help of Strongbow, the Earl of Pembroke, to conquer Dublin. Following Mac Murchada's death, Strongbow declared himself King of Leinster after gaining control of the city. In response to Strongbow's successful invasion, Henry II of England affirmed his ultimate sovereignty by mounting a larger invasion in 1171 and pronounced himself Lord of Ireland. Around this time, the county of the City of Dublin was established along with certain liberties adjacent to the city proper. This continued down to 1840 when the barony of Dublin City was separated from the barony of Dublin. Since 2001, both baronies have been redesignated as the City of Dublin.
Dublin Castle, which became the centre of Anglo-Norman power in Ireland, was founded in 1204 as a major defensive work on the orders of King John of England. Following the appointment of the first Lord Mayor of Dublin in 1229, the city expanded and had a population of 8,000 by the end of the 13th century. Dublin prospered as a trade centre, despite an attempt by King Robert the Bruce of Scotland to capture the city in 1317. It remained a relatively small walled medieval town during the 14th century and was under constant threat from the surrounding native clans. In 1348, the Black Death, a lethal plague which had ravaged Europe, took hold in Dublin and killed thousands over the following decade.
Dublin was the heart of the area known as the Pale, a narrow strip of English settlement along the eastern coast, under the control of the English Crown. The Tudor conquest of Ireland in the 16th century spelt a new era for Dublin, with the city enjoying a renewed prominence as the centre of administrative rule in Ireland where English control and settlement had become much more extensive. Determined to make Dublin a Protestant city, Queen Elizabeth I established Trinity College in 1592 as a solely Protestant university and ordered that the Catholic St. Patrick's and Christ Church cathedrals be converted to the Protestant church. The earliest map of the city of Dublin dates from 1610, and was by John Speed.
The city had a population of 21,000 in 1640 before a plague from 1649 to 1651 wiped out almost half of the inhabitants. However, the city prospered again soon after as a result of the wool and linen trade with England and reached a population of over 50,000 in 1700. By 1698 the manufacture of wool employed 12,000 people.

### Early modern

As the city continued to prosper during the 18th century, Georgian Dublin became, for a short period, the second-largest city of the British Empire and the fifth largest city in Europe, with the population exceeding 130,000. While some medieval streets and layouts (including the areas around Temple Bar, Aungier Street, Capel Street and Thomas Street) were less affected by the wave of Georgian reconstruction, much of Dublin's architecture and layout dates from this period.
Dublin grew even more dramatically during the 18th century, with the construction of many new districts and buildings, such as Merrion Square, Parliament House and the Royal Exchange. The Wide Streets Commission was established in 1757 at the request of Dublin Corporation to govern architectural standards on the layout of streets, bridges and buildings. In 1759, the Guinness brewery was founded, and would eventually grow to become the largest brewery in the world and the largest employer in Dublin. During the 1700s, linen was not subject to the same trade restrictions with England as wool, and became the most important Irish export. Over 1.5 million yards of linen was exported from Ireland in 1710, rising to almost 19 million yards by 1779.

### Late modern and contemporary

Dublin suffered a period of political and economic decline during the 19th century following the Acts of Union 1800, under which the seat of government was transferred to the Westminster Parliament in London. The city played no major role in the Industrial Revolution, but remained the centre of administration and a transport hub for most of the island. Ireland had no significant sources of coal, the fuel of the time, and Dublin was not a centre of ship manufacturing, the other main driver of industrial development in Britain and Ireland. Belfast developed faster than Dublin during this period on a mixture of international trade, factory-based linen cloth production and shipbuilding. By 1814, the population of Dublin was 175,319 as counted under the Population Act, making the population of Dublin higher than any town in England except London.
The Easter Rising of 1916, the Irish War of Independence, and the subsequent Irish Civil War resulted in a significant amount of physical destruction in central Dublin. The Government of the Irish Free State rebuilt the city centre and located the new parliament, the Oireachtas, in Leinster House. Since the beginning of Norman rule in the 12th century, the city has functioned as the capital in varying geopolitical entities: Lordship of Ireland (1171–1541), Kingdom of Ireland (1541–1800), as part of the United Kingdom of Great Britain and Ireland (1801–1922), and the Irish Republic (1919–1922). Following the partition of Ireland in 1922, it became the capital of the Irish Free State (1922–1937) and now is the capital of Ireland. One of the memorials to commemorate that time is the Garden of Remembrance.
Dublin was also a victim of the Northern Irish Troubles, although during this 30-year conflict, violence mainly occurred within Northern Ireland. A Loyalist paramilitary group, the Ulster Volunteer Force, bombed the city during this time – notably in an atrocity known as the Dublin and Monaghan bombings in which 34 people died, mainly in central Dublin.
Large parts of Georgian Dublin were demolished or substantially redeveloped in the mid-20th century during a boom in office building. After this boom, the recessions of the 1970s and 1980s slowed down the pace of building. Cumulatively, this led to a large decline in the number of people living in the centre of the city, and by 1985 the city had approximately 150 acres of derelict land which had been earmarked for development and 10 million square feet (900 thousand square metres) of office space.
Since 1997, the landscape of Dublin has changed. The city was at the forefront of Ireland's economic expansion during the Celtic Tiger period, with private sector and state development of housing, transport and business. Following an economic decline during the Great Recession, Dublin has rebounded and as of 2017 has close to full employment, but has a significant problem with housing supply in both the city and surrounds.

## Government
### Local

Dublin City Council is a unicameral assembly of 63 members elected every five years from local electoral areas. It is presided over by the Lord Mayor, who is elected for a yearly term and resides in Dublin's Mansion House. Council meetings occur at Dublin City Hall, while most of its administrative activities are based in the Civic Offices on Wood Quay. The party or coalition of parties with the majority of seats assigns committee members, introduces policies, and proposes the Lord Mayor. The Council passes an annual budget for spending on areas such as housing, traffic management, refuse, drainage, and planning. The Dublin City Manager is responsible for implementing City Council decisions but also has considerable executive power. Other neighbouring Dublin County Councils include South Dublin County Council, Fingal County Council and Dun Laoghaire-Rathdown County Council.

### National

As the capital city, Dublin is the seat of the national parliament of Ireland, the Oireachtas. It is composed of the President of Ireland, Dáil Éireann as the house of representatives, and Seanad Éireann as the upper house. The President resides in Áras an Uachtaráin in Phoenix Park, while both houses of the Oireachtas meet in Leinster House, a former ducal residence on Kildare Street. It has been the home of the Irish parliament since the foundation of the Irish Free State in 1922. The old Irish Houses of Parliament of the Kingdom of Ireland, which dissolved in 1801, are located in College Green.
Government Buildings house the Department of the Taoiseach, the Council Chamber, the Department of Finance and the Office of the Attorney General. It consists of a main building (completed 1911) with two wings (completed 1921). It was designed by Thomas Manley Dean and Sir Aston Webb as the Royal College of Science. The First Dáil originally met in the Mansion House in 1919. The Irish Free State government took over the two wings of the building to serve as a temporary home for some ministries, while the central building became the College of Technology until 1989. Although both it and Leinster House were intended to be temporary locations, they became the permanent homes of parliament from then on.
For elections to Dáil Éireann, there are five constituencies that are wholly or predominantly in the Dublin City area: Dublin Central (4 seats), Dublin Bay North (5 seats), Dublin North-West (3 seats), Dublin South-Central (4 seats) and Dublin Bay South (4 seats). Twenty TDs are elected in total. The constituency of Dublin West (4 seats) is partially in Dublin City, but predominantly in Fingal.
At the 2024 general election, the Dublin city area elected 5 Sinn Féin, 4 Fianna Fáil, 4 Social Democrats, 3 Fine Gael, 2 Labour and 2 Independents.

## Geography
### Landscape

Dublin is situated at the mouth of the River Liffey and its urban area encompasses approximately 345 square kilometres (133 sq mi) in east-central Ireland. It is bordered by the Dublin Mountains, a low mountain range and sub range of the Wicklow Mountains, to the south and surrounded by flat farmland to the north and west.

#### Watercourses

The River Liffey divides the city in two, between the Northside and the Southside. The Liffey bends at Leixlip from a northeasterly route to a predominantly eastward direction, and this point also marks the transition to urban development from more agricultural land usage. The city itself was founded where the River Poddle met the Liffey, and the early Viking settlement was also facilitated by the small Steine or Steyne River, the larger Camac and the Bradogue, in particular.
Two secondary rivers further divide the city: the River Tolka, running southeast into Dublin Bay, and the River Dodder running northeast to near the mouth of the Liffey, and these and the Liffey have multiple tributaries. A number of lesser rivers and streams also flow to the sea within the suburban parts of the city.
Two canals – the Grand Canal on the southside and the Royal Canal on the northside – ring the inner city on their way from the west, both connecting with the River Shannon.

### Climate

Similar to much of the rest of northwestern Europe, Dublin experiences a maritime climate (Cfb) with mild-warm summers, cool winters, and a lack of temperature extremes. At Merrion Square, the coldest month is February, with an average minimum temperature of 4.1 °C (39.4 °F), and the warmest month is July, with an average maximum temperature of 20.1 °C (68.2 °F). Due to the urban heat island effect, Dublin city has the warmest summertime nights in Ireland. The average minimum temperature at Merrion Square in July is 13.5 °C (56.3 °F), and the lowest July temperature ever recorded at the station was 7.8 °C (46.0 °F) on 3 July 1974.
The highest temperature officially recorded in Dublin is 33.1 °C (91.6 °F) on 18 July 2022, at the Phoenix Park. A non-official record of 33.5 °C (92.3 °F) was also recorded at Phoenix Park in July 1876
Dublin's sheltered location on the east coast makes it the driest place in Ireland, receiving only about half the rainfall of the west coast. Ringsend in the south of the city records the lowest rainfall in the country, with an average annual precipitation of 683 mm (27 in), with the average annual precipitation in the city centre being 726 mm (29 in). At Merrion Square, the wettest year and driest year on record occurred within 5 years of each other, with 1953 receiving just 463.1 mm (18.23 in) of rainfall, while 1958 recorded 1,022.5 mm (40.26 in). The main precipitation in winter is rain; however snow showers do occur between November and March. Hail is more common than snow. Strong Atlantic winds are most common in autumn. These winds can affect Dublin, but due to its easterly location, it is least affected compared to other parts of the country. However, in winter, easterly winds render the city colder and more prone to snow showers.
The city experiences long summer days and short winter days. Based on satellite observations, Met Éireann estimates that Dublin's coastal areas typically receive over 1,600 hours of sunshine per year, with the climate getting progressively duller inland. Dublin airport, located north of city and about 10 kilometres (6.2 mi) from the coast, records an average of 1,485 hours of sunshine per year. The station at Dublin airport has been maintaining climate records since November 1941. The sunniest year on record was 1,740 hours in 1959, and the dullest year was 1987 with 1,240 hours of sunshine. The lowest amount of monthly sunshine on record was 16.4 hours in January 1996, while the highest was 305.9 hours in July 1955.
In the 20th century, smog and air-pollution were an issue in the city, precipitating a ban on bituminous fuels across Dublin. The ban was implemented in 1990 to address black smoke concentrations, that had been linked to cardiovascular and respiratory deaths in residents. Since the ban, non-trauma death rates, respiratory death rates and cardiovascular death rates have declined – by an estimated 350 deaths annually.

## Cityscape
### Areas
#### City centre

The historic city centre of Dublin is encircled by the Royal Canal and Grand Canal, bounded to the west by Heuston railway station and Phoenix Park, and to the east by the IFSC and the Docklands. O'Connell Street is the main thoroughfare of the inner city and many Dublin Bus routes, as well as the Green line of the Luas, have a stop at O'Connell Street. The main shopping streets of the inner city include Henry Street on the Northside, and Grafton Street on the Southside.
In some tourism and real-estate marketing contexts, inner Dublin is sometimes divided into a number of quarters. These include the Medieval Quarter (in the area of Dublin Castle, Christ Church and St Patrick's Cathedral and the old city walls), the Georgian Quarter (including the area around St Stephen's Green, Trinity College, and Merrion Square), the Docklands Quarter (around the Dublin Docklands and Silicon Docks), the Cultural Quarter (around Temple Bar), and Creative Quarter (between South William Street and George's Street).

#### Suburbs

Dublin has dozens of suburbs; northside suburbs include Blanchardstown, Finglas, Ballymun, Clontarf, Raheny, Malahide and Howth, while southside suburbs include Tallaght, Sandyford, Templeogue, Drimnagh, Rathmines, Dún Laoghaire and Dalkey.
Starting in the late 2010s, there was a significant amount of high density residential developments in the suburbs of Dublin, with mid to high-rise apartments being built in Sandyford, Ashtown, and Tallaght.

### Cultural divide

A north–south division once, to some extent, traditionally existed, with the River Liffey as the divider. The southside was, in recent times, generally seen as being more affluent and genteel than the northside. There have also been some social divisions evident between the coastal suburbs in the east of the city, and the newer developments further to the west.

### Landmarks

Dublin has many landmarks and monuments dating back hundreds of years. One of the oldest is Dublin Castle, which was first founded as a major defensive work on the orders of England's King John in 1204, shortly after the Norman invasion of Ireland in 1169, when it was commanded that a castle be built with strong walls and good ditches for the defence of the city, the administration of justice, and the protection of the King's treasure. Largely complete by 1230, the castle was of typical Norman courtyard design, with a central square without a keep, bounded on all sides by tall defensive walls and protected at each corner by a circular tower. Sited to the south-east of Norman Dublin, the castle formed one corner of the outer perimeter of the city, using the River Poddle as a natural means of defence.
One of Dublin's most prominent landmarks is the Spire of Dublin, officially entitled the "Monument of Light". It is a 121.2-metre (398 ft) conical spire made of stainless steel, completed in 2003 and located on O'Connell Street, where it meets Henry Street and North Earl Street. It replaced Nelson's Pillar and is intended to mark Dublin's place in the 21st century. The spire was designed by Ian Ritchie Architects, who sought an "Elegant and dynamic simplicity bridging art and technology". The base of the monument is lit and the top is illuminated to provide a beacon in the night sky across the city.
The Old Library of Trinity College Dublin, holding the Book of Kells, is one of the city's most visited sites. The Book of Kells is an illustrated manuscript created by Irish monks circa 800 AD. The Ha'penny Bridge, an iron footbridge over the River Liffey, is one of the most photographed sights in Dublin and is considered to be one of Dublin's most iconic landmarks.

### Parks

There are 302 parks and 66 green spaces within the Dublin City Council area as of 2018, with the council managing over 1,500 hectares (3,700 acres) of parks. Public parks include the Phoenix Park, Herbert Park, St Stephen's Green, Saint Anne's Park and Bull Island. The Phoenix Park is about 3 km (2 miles) west of the city centre, north of the River Liffey. Its 16-kilometre (10 mi) perimeter wall encloses 707 hectares (1,750 acres), making it one of the largest walled city parks in Europe. It includes large areas of grassland and tree-lined avenues, and since the 17th century has been home to a herd of wild fallow deer. The residence of the President of Ireland (Áras an Uachtaráin), which was built in 1751, is located in the park. The park is also home to Dublin Zoo, Ashtown Castle, and the official residence of the United States Ambassador. Music concerts are also sometimes held in the park.
St Stephen's Green is adjacent to one of Dublin's main shopping streets, Grafton Street, and to a shopping centre named after it, while on its surrounding streets are the offices of a number of public bodies.
Saint Anne's Park is a public park and recreational facility, shared between Raheny and Clontarf, both suburbs on the Northside. The park, the second largest municipal park in Dublin, is part of a former 2-square-kilometre (0.8 sq mi; 500-acre) estate assembled by members of the Guinness family, beginning with Benjamin Lee Guinness in 1835. The largest municipal park is adjacent (North) Bull Island, also shared between Clontarf and Raheny, featuring a 5 km beach, Dollymount Strand.

### City boundaries

From 1842, the boundaries of the city were comprehended by the baronies of Dublin City and the barony of Dublin. Over time, the city has absorbed area previously administered as part of County Dublin (now the three counties of Dún Laoghaire–Rathdown, Fingal and South Dublin), with a change in 1985 also returning areas to the county.
Changes to city boundaries :
| Year | Changes |
| 1900 | Transfer of former urban districts of Clontarf, Drumcondra, Clonliffe and Glasnevin, and New Kilmainham from County Dublin |
| 1930 | Transfer of former urban districts of Pembroke and Rathmines and Rathgar from County Dublin |
| 1931 | Transfer of Drumcondra, Glasnevin, Donnybrook and Terenure from County Dublin |
| 1941 | Transfer of Crumlin from County Dublin |
| 1942 | Transfer of former urban district of Howth from County Dublin |
| 1953 | Transfer of Finglas, Coolock and Ballyfermot from County Dublin. |
| 1985 | Transfer of Santry and Phoenix Park from County Dublin; transfer of Howth, Sutton and parts of Kilbarrack including Bayside to County Dublin |
| 1994 | Alterations to western boundaries in the vicinities of Ballyfermot and Cabra on establishment of new counties |

## Economy

The Dublin region is the economic centre of Ireland, and was at the forefront of the country's economic expansion during the Celtic Tiger period. In 2009, Dublin was listed as the fourth richest city in the world by purchasing power and 10th richest by personal income. According to Mercer's 2011 Worldwide Cost of Living Survey, Dublin was the 13th most expensive city in the European Union (down from 10th in 2010) and the 58th most expensive place to live in the world (down from 42nd in 2010). As of 2017, approximately 874,400 people were employed in the Greater Dublin Area. Around 60% of people who are employed in Ireland's financial, ICT, and professional sectors are located in this area.
A number of Dublin's traditional industries, such as food processing, textile manufacturing, brewing, and distilling have gradually declined, although Guinness has been brewed at the St. James's Gate Brewery since 1759. Economic improvements in the 1990s attracted a number of global pharmaceutical, information and communications technology companies to the city and Greater Dublin Area. Companies such as Microsoft, Google, Amazon, eBay, PayPal, Yahoo!, Facebook, X, Accenture, TikTok and Pfizer now have European headquarters or operational bases in the city with several located in enterprise clusters like the Digital Hub and Silicon Docks. The presence of these companies has driven economic expansion in the city and led to Dublin sometimes being referred to as the "Tech Capital of Europe".
Financial services have also become important to the city since the establishment of Dublin's International Financial Services Centre in 1987. More than 500 operations are approved to trade under the IFSC programme. The centre is host to half of the world's top 50 banks and to half of the top 20 insurance companies. Many international firms have established major headquarters in the city, such as Citibank. The Irish Stock Exchange (ISEQ), Internet Neutral Exchange (INEX) and Irish Enterprise Exchange (IEX) are also located in Dublin. Dublin has been positioned as one of the main cities vying to host Financial Services companies hoping to retain access to the Eurozone after Brexit. The Celtic Tiger also led to a temporary boom in construction, with large redevelopment projects in the Dublin Docklands and Spencer Dock. Completed projects include the Convention Centre, the 3Arena, and the Bord Gáis Energy Theatre.
In the second quarter of 2018, Dublin touched its lowest unemployment rate in a decade, when it fell down to 5.7% as reported by the Dublin Economic Monitor. In November 2022, Dublin was ranked as one of the worst cities in the world for travel, health and cost of living. On 24 September 2022, thousands took to the streets in protest against the cost of living crisis.
As of 2024, the Gross Domestic Product of Dublin is €253.6 billion, meaning it has one of the biggest city economies in the European Union.

## Transport
### Road

The road network in Ireland is primarily focused on Dublin. The M50 motorway, a semi-ring road which runs around the south, west and north of the city, connects important national primary routes to the rest of the country. In 2008, the West-Link toll bridge was replaced by the eFlow barrier-free tolling system, with a three-tiered charge system based on electronic tags and car pre-registration.
The first phase of a proposed eastern bypass for the city is the Dublin Port Tunnel, which officially opened in 2006 to mainly cater for heavy vehicles. The tunnel connects Dublin Port and the M1 motorway close to Dublin Airport. The city is also surrounded by an inner and outer orbital route. The inner orbital route runs approximately around the heart of the Georgian city and the outer orbital route runs primarily along the natural circle formed by Dublin's two canals, the Grand Canal and the Royal Canal, as well as the North and South Circular Roads.
The 2016 TomTom Traffic Index ranked Dublin the 15th most congested city in the world and the 7th most congested in Europe.

#### Bus

Dublin is served by a network of nearly 200 bus routes which cover the city and suburbs. The majority of these are provided by Dublin Bus, with a modest number having been transferred to Go Ahead Ireland in 2018. A number of smaller companies also operate. Fares are generally calculated on a stage system based on distance travelled. There are several different levels of fares, which apply on most services. A "Real Time Passenger Information" system was introduced at Dublin Bus bus stops in 2012 in which signs relay display the projected time of the next buses' arrival based on its GPS position. The National Transport Authority is responsible for integration of bus and rail services in Dublin and has been involved in introducing a pre-paid smart card, called a TFI Leap Card, which can be used on all of Dublin's public transport services.
The BusConnects programme includes a number of proposed improvements to Dublin's bus network, including new spine and orbital routes. The spine routes are intended to increase the frequency of buses along major corridors, and the orbital routes aim to "provide connections between suburbs and town centres, without having to travel into the City Centre". In 2022, Dublin Bus began the process of electrifying its fleet with new battery-powered buses, with plans for 85% of Dublin buses to be zero-emission by 2032.

#### Cycling

The 2011 census indicated that 5.9% of commuters in Dublin cycled. A 2013 report by Dublin City Council on traffic flows crossing the canals in and out of the city found that just under 10% of all traffic was made up of cyclists, representing an increase of 14.1% over 2012 and an 87.2% increase over 2006 levels. The increase was attributed to measures such as the Dublinbikes bike rental scheme, the provision of cycle lanes, public awareness campaigns to promote cycling and the introduction of the 30 km/h city centre speed limit.
Dublin City Council began installing cycle lanes and tracks throughout the city in the 1990s, and as of 2012 the city had over 200 kilometres (120 miles) of specific on- and off-road tracks for cyclists. In 2011, the city was ranked 9th of major world cities on the Copenhagenize Index of Bicycle-Friendly Cities. The same index showed a fall to 15th in 2015, and Dublin was outside the top 20 in 2017.
Dublinbikes is a self-service bicycle rental scheme which has been in operation in Dublin since 2009. Sponsored by JCDecaux and Just Eat, the scheme consists of hundreds of unisex bicycles stationed at 44 terminals throughout the city centre. Users must make a subscription for either an annual Long Term Hire Card or purchase a three-day ticket. As of 2018, Dublinbikes had over 66,000 long-term subscribers making over 2 million journeys per year.

### Rail

Heuston and Connolly stations are the two main railway termini in Dublin. Operated by Iarnród Éireann, the Dublin Suburban Rail network consists of five railway lines serving the Greater Dublin Area and commuter towns such as Drogheda and Dundalk in County Louth, Gorey in County Wexford, and extending as far as Portlaoise in County Laois, and once a day to Newry. One of the five lines is the electrified Dublin Area Rapid Transit (DART) line, which runs primarily along the coast of Dublin, comprising 31 stations, from Malahide and Howth southwards as far as Bray and Greystones in County Wicklow. Commuter rail operates on the other four lines using Irish Rail diesel multiple units. In 2013, passengers for DART and Dublin Suburban lines were 16 million and 11.7 million, respectively (around 75% of all Irish Rail passengers).
Dublin once had an extensive system of trams but this was largely phased out by 1949. A new light rail system, often described as a tram system, the Luas, was launched in 2004, and is run by Transdev Ireland (under contract from Transport Infrastructure Ireland), carrying over 34 million passengers annually. The network consists of two interconnecting lines; the Red Line links the Docklands and city centre with the south-western suburbs of Tallaght and Saggart, while the Green Line connects northern inner city suburbs and the main city centre with suburbs to the south of the city including Sandyford and Brides Glen, mostly along the former route of the Harcourt Street railway line. Together these lines comprise a total 67 stops and 44.5 kilometres (27.7 mi) of track. Construction of a 6 km extension to the Green Line, bringing it into the north of the city, commenced in June 2013 and was opened for passenger travel on 9 December 2017.
A metro service is proposed under the name of Metrolink, and planned to run from Dublin's northside to Charlemont via Dublin Airport and St. Stephen's Green.

### Rail and ferry

Dublin Connolly is connected by bus to Dublin Port and ferries run by Irish Ferries and Stena Line to Holyhead for connecting trains on the North Wales Coast Line to Chester, Crewe and London Euston. Dublin Connolly to Dublin Port can be reached via Amiens Street, Dublin into Store Street or by Luas via Busáras where Dublin Bus operates services to the Ferry Terminal.

### Air
#### Dublin Airport

Dublin Airport (owned and operated by DAA) is located north of Dublin city, near Swords in the administrative county of Fingal. The headquarters of Ireland's flag carrier Aer Lingus and regional airline CityJet are located there, and those of low-cost carrier Ryanair nearby. The airport offers a short and medium-haul network, domestic services to regional airports in Ireland, and long-haul services to the United States, Canada, the Middle East and Hong Kong. Dublin Airport is the 11th busiest in the European Union, and by far the busiest airport on the island of Ireland.
In 2015 and 2016, transatlantic traffic grew, with 158 summer flights a week to North America, making it the sixth largest European hub for that route over the year. Transatlantic traffic was also the fastest-growing segment of the market for the airport in 2016, in which a 16% increase from 2015 brought the yearly number of passengers travelling between Dublin and North America to 2.9 million.
From 2010 to 2016, Dublin Airport saw an increase of nearly 9.5 million passengers in its annual traffic, as the number of commercial aircraft movements has similarly followed a growth trend from 163,703 in 2013 to 191,233 in 2015.
In 2019, Dublin Airport was the 12th busiest airport in Europe, with almost 33 million passengers passing through the airport.

#### Other air transport

Dublin is also served by Weston Airport and other small facilities, by a range of helicopter operators, and the military and some State services use Casement Aerodrome nearby.

### Cuisine

As of the 2024 Michelin Guide, seven Dublin restaurants shared ten Michelin stars – including Restaurant Patrick Guilbaud, Liath and Chapter One with two. Irish-born Kevin Thornton was awarded two Michelin stars in 2001 – though his restaurant, Thornton's, closed in 2016. The Dublin Institute of Technology commenced a bachelor's degree in culinary skills in 1999.
Historically, Irish coffee houses and cafes were associated with those working in media. Since the beginning of the 21st century, with the growth of apartment living in the city, Dublin's cafés attracted younger patrons looking for an informal gathering place and an ad hoc office. Cafés became more popular in the city, and Irish-owned coffee chains like Java Republic, Insomnia, and O'Brien's Sandwich Bars now compete internationally. In 2008, Irish barista Stephen Morrissey won the title of World Barista Champion.
Immigrant groups, such as Chinese, Japanese and Italian émigrés, have also opened restaurants around Dublin. A number of South-East Asians immigrated from places such as Hong Kong, Malaysia and Mainland China to Dublin during the 1960s and opened restaurants featuring their cuisines. Modern Irish adaptions of Chinese cuisine include the Spice bag, a takeaway dish consisting of mainly chicken, chips and vegetables. In 2020, it was voted 'Ireland's Favourite Takeaway Dish' in the Just Eat National Takeaway Awards.

## English and Irish languages

Dublin was traditionally a city of two languages, English and Irish, a situation found also in the area around it, the Pale. The Irish of County Dublin represented the easternmost extension of a broad central dialect area which stretched between Leinster and Connacht, but had its own local characteristics. It may also have been influenced by the east Ulster dialect of County Meath and County Louth to the north.
In the words of a 16th-century English administrator, William Gerard (1518–1581): "All Englishe, and the most part with delight, even in Dublin, speak Irishe". The Old English historian Richard Stanihurst (1547–1618) wrote as follows: "When their posteritie became not altogither so warie in keeping, as their ancestors were valiant in conquering, the Irish language was free dennized in the English Pale: this canker tooke such deep root, as the bodie that before was whole and sound, was by little and little festered, and in manner wholly putrified".
English authorities of the Cromwellian period accepted the fact that Irish was widely spoken in the city and its surrounds. In 1655 several local dignitaries were ordered to oversee a lecture in Irish to be given in Dublin. In March 1656 a converted Catholic priest, Séamas Corcy, was appointed to preach in Irish at Bride's parish every Sunday, and was also ordered to preach at Drogheda and Athy. In 1657 the English colonists in Dublin presented a petition to the Municipal Council complaining that in Dublin itself "there is Irish commonly and usually spoken".
In early 18th century Dublin, Irish was the language of a group of poets and scribes led by Seán and Tadhg Ó Neachtain. Scribal activity in Irish persisted in Dublin right through the 18th century. There were still native Irish speakers in County Dublin at the time of the 1851 census.
Though the number of Irish speakers declined throughout Ireland in the 19th century, the end of the century saw a Gaelic revival, centred in Dublin and accompanied by renewed literary activity. This was the harbinger of a steady renewal of urban Irish, though with new characteristics of its own.

### Current era

The native language of most Dubliners today is English, and several local dialects are subsumed under the label Dublin English. Dublin also has many thousands of habitual Irish speakers, with the 2016 census showing that daily speakers (outside the education system) numbered 14,903. They form part of an urban Irish-speaking cohort which is generally better-educated than monoglot English speakers.
The Dublin Irish-speaking cohort is supported by a number of Irish-medium schools. There are 12,950 students in the Dublin region attending 34 gaelscoileanna (Irish-language primary schools) and 10 gaelcholáistí (Irish-language secondary schools).
Two Irish language radio stations, Raidió Na Life and RTÉ Raidió na Gaeltachta, have studios in the city, and the online station Raidió Rí-Rá broadcasts from studios in the city. A number of Irish language agencies are also located in the capital. Conradh na Gaeilge offers language classes and is used as a meeting place for different groups. The closest Gaeltacht to Dublin is the County Meath Gaeltacht of Ráth Cairn and Baile Ghib which is 55 km (34 mi) away.

## International relations

Dublin city council has an International Relations Unit, established in 2007. It works on hosting of international delegations, staff exchanges, international promotion of the city, twinning and partnerships, work with multi-city organisations such as Eurocities, economic partnerships and advice to other Council units.

### Twin and partner cities

Dublin is twinned with five places:
| City | Nation | Since |
| San Jose | United States | 1986 |
| Liverpool | United Kingdom | 1997 |
| Barcelona | Spain | 1998 |
| Beijing | China | 2011 |
| Ramallah | Palestine | 2023 |
The city also has "friendship" or "co-operation agreements" with a number of other cities: Moscow (since 2009) and St Petersburg (since 2010) in Russia and Guadalajara in Mexico (since 2013), and has previously proposed an agreement with Rio de Janeiro also. Previous agreements have included those with Mexico City (2014−2018), Tbilisi in Georgia (2014−2017) and Wuhan in China (2016−2019).
