# Hong Kong Island

Hong Kong Island (Chinese: 香港島; Jyutping: Hoeng1 gong2 dou2; Cantonese Yale: Hēunggóng dóu) is an island in the southern part of Hong Kong. The island, known originally and on road signs simply as "Hong Kong", had a population of 1,289,500 and a population density of 16,390 per square kilometre (42,400/sq mi), as of 2023. It is the second largest island in Hong Kong, with the largest being Lantau Island. Hong Kong Island forms one of the three areas of Hong Kong, with the other two being Kowloon and the New Territories.
In 1842, following the Qing dynasty's defeat at the First Opium War (1839–1842), Hong Kong Island was formally ceded in perpetuity to the United Kingdom under the Treaty of Nanking. The City of Victoria was then established on the island by British forces in honour of Queen Victoria. At that time, the island had a population of about 3,000 inhabitants scattered in a dozen fishing villages.
The northern-east part of the island, being known as the Central area is the historical, political, and economic centre of Hong Kong, with many government buildings being in the area, namely the Government House, Central Government Complex, Legislative Council Complex, Hong Kong Court of Final Appeal and High Court of Hong Kong. Many financial institutes and banks such as the Hong Kong Stock Exchange, Hong Kong Monetary Authority, HSBC and Bank of China are also based in the area.
The northern coast of the island forms the southern shore of the Victoria Harbour, which is largely responsible for the development of Hong Kong due to its deep waters favoured by large trade ships. The island is home to many famous tourists sights, such as "The Peak", Ocean Park, Former Central Police Station Compound, Murray House, and many other historical sites and various large shopping centres. The mountain ranges across the island are also famous for hiking.
The northern part of Hong Kong Island, together with Kowloon and Tsuen Wan New Town, forms the core urban area of Hong Kong. Their combined area is approximately 88.3 square kilometres (34.1 square miles) and their combined population is approximately 3,156,500, reflecting a population density of 35,700 people/km$^2$ (92,000 people/sq mi).
The island is often referred to locally as "Hong Kong side" or "Island side". The suffix "-side" is also applied to other locations in Hong Kong (e.g. China-side and Kowloon Walled City-side), the sole remnant of which being the "Kowloon side" when referring to the two sides of the Victoria Harbour.

## History
### Prehistoric and Imperial China period

Human settlement of the area dates back 6,000 years ago, as evidenced by Neolithic artifacts discovered in Stanley, Hong Kong Island.
In 214 BC, the Qin dynasty defeated the Baiyue, and absorbed areas of what is now Guangdong, Guangxi, and northern Vietnam. Hong Kong Island was part of the annexed land and was listed under the jurisdiction of Panyu County (番禺縣) of the Nanhai Commandery (南海郡). On the sixth year of the Eastern Jin dynasty (AD 331), Hong Kong Island was listed under the jurisdiction of Baoan County (寶安縣).
Copper coins from the Sui, Tang and Song dynasty were unearthed in where the Royal Hong Kong Yacht Club is presently located at, on where Kellett Island would have been prior to the land reclamation connecting the island to Causeway Bay in 1969. This suggests that during these periods of times, the island already had its own commercial activity. Song dynasty copper coins served as universal currency in transregional trade.
During the Wanli period of the Ming dynasty (1573), Hong Kong Island belonged to the territory of Xin'an County, and remained so until 1661, when the great clearance was issued by the Shunzhi Emperor of the Qing dynasty, forcing residents in coastal areas of Guangdong, Fujian, Zhejiang, Jiangnan, and Shandong to move in-land, to prevent the loyalists of the Ming dynasty in Formosa from approaching the shores of the Mainland and seek help from residents of the coastal areas.
The ban was lifted when the remnants of the Ming dynasty were exterminated in 1669, though not many original residents of Hong Kong Island returned to the area. Piracy was rampant in the area until the island was ceded to the United Kingdom in 1842.

### British colony

Following the First Opium War (1839–1842), Hong Kong Island was ceded to Great Britain in 1842 under the Treaty of Nanking and the territory became a Crown colony. At the time, the island's population was only 7,450.

#### Japanese invasion and occupation

The Second World War was a dark period for Hong Kong. In the 1930s, the British anticipated a Japanese attack on Hong Kong. As Wong Nai Chung Gap was a strategically important location of defence, large-scale defensive works were constructed there, including anti-aircraft batteries, howitzers and machine gun nests.
The Battle of Hong Kong began on 8 December 1941. British, Canadian and Indian armies and the Hong Kong Volunteer Defence Forces resisted the Japanese invasion commanded by Sakai Takashi, which began eight hours after the attack on Pearl Harbor. However, the Japanese took control of the Hong Kong skies on the first day of attack and outnumbered the defenders, which retreated from the Gin Drinkers Line and consequently from Kowloon under heavy aerial bombardment and artillery barrage.
On 18 December, the Japanese had conquered North Point, reaching the Wong Nai Chung Gap on the following day. English, Scottish forces and the Canadian Winnipeg Grenadiers vigorously defended the crucial point of Wong Nai Chung Gap, and for a while successfully secured the passage between Central and the secluded southern parts of the island. Japanese casualties were about 600. However, Allied forces there were ultimately defeated by the Japanese on 23 December, and Wong Nai Chung Reservoir was lost. As Wan Chai Gap had also fallen that same day, the British had no choice but to surrender.
Hong Kong surrendered to the Japanese on 25 December 1941, thereafter often called "Black Christmas" by locals as the surrender was on Christmas. The Governor of Hong Kong, Mark Young, surrendered in-person at the temporary Japanese headquarters, on the third floor of the Peninsula Hotel, thus beginning the Japanese occupation of Hong Kong. Isogai Rensuke became the first Japanese governor of Hong Kong. Hyper-inflation and food rationing followed; and the Japanese declared Hong Kong Dollars illegal. The Japanese enforced a repatriation policy throughout the period of occupation due to the scarcity of food and the possible counter-attack of the Allies. As a result, the unemployed were deported to the Mainland, and the population of Hong Kong had dwindled from 1.6 million in 1941 to 600,000 in 1945.

#### Post Second World War

The population of Hong Kong Island grew exponentially after the Second World War and the Communist revolution in China. It became apparent that the lands in the old Central District were insufficient to accommodate the population. Many undeveloped or underdeveloped areas Hong Kong Island such as North Point, Shau Kei Wan, Aberdeen and Wong Chuk Hang began its development and urbanisation. These areas initially started off as industrialised areas, with some areas such as Quarry Bay, Wan Chai and Causeway Bay later becoming new commercial centres when Hong Kong moved away from its period of industrialisation, as these areas provided relatively cheaper rent than the traditional commercial district of Central.
On 1 July 1997, the sovereignty of Hong Kong Island was transferred to the People's Republic of China alongside Kowloon Peninsula and the New Territories, ending 156 years of British rule on Hong Kong Island.

## Transportation
### Rail

Seven of the MTR rapid transit system's ten lines service Hong Kong Island. The Island line and South Island line run exclusively on the four districts of Hong Kong Island, with the Island line serving the north shore at 17 stations, and the South Island line connecting four stations on Ap Lei Chau and in Wong Chuk Hang to the north shore at Admiralty station. Five MTR lines – the Tsuen Wan line, the Tseung Kwan O line, the Tung Chung line, the Airport Express – connect the north shore with Kowloon and provide onward service to the New Territories, and the East Rail line which provides another cross-harbour connection upon its extension from Hung Hom station to Admiralty station. In future, the planned North Island line infrastructure project would extend both the Tung Chung line and the Tseung Kwan O line to connect them to each other, forming a route parallel to the middle section of the Island line.
Two other rail systems, Hong Kong Tramways and the Peak Tram, also run exclusively on Hong Kong Island. The former runs mostly parallel to the Island line between Kennedy Town and Shau Kei Wan, with a loop linking Causeway Bay and Happy Valley; the latter is a funicular linking Central District to Victoria Peak.

### Maritime Transport

Hong Kong Island has four ferry terminals, them being the Central Ferry Piers, North Point Ferry Pier, Sai Wan Ho Ferry Pier and Wan Chai Ferry Pier. Frequently ferry services are provided from these piers to the Kowloon Peninsula and the outlying islands. A departure terminal, the Hong Kong Macau Ferry Terminal is located in Sheung Wan to provide turbojet ferry services to Macau.
A tourist sightseeing ferry service, branded as the "Water Taxi" is also offered. The ferry service travels in the Victoria Harbour to sightseeing attractions of Hong Kong, such as the Hong Kong Observation Wheel, International Financial Centre, Tsim Sha Tsui Promenade, West Kowloon Cultural District and Kai Tak Cruise Terminal. It has 4 drop off points.
Public piers are also alongside the Victoria Harbour, such as the famous now-demolished Queen's Pier in Central and now-relocated Blake Pier in Stanley, which mainly provides passenger pick-up and drop-off services for small barges, yachts and sightseeing boats. Public piers are located mainly along the Victoria Harbour mainly in Causeway Bay, Central, Shau Kei Wan, Wan Chai, and also in Aberdeen, Ap Lei Chau and Stanley, places in the Southern District.

### Roads

Major roads on Hong Kong Island include Connaught Road, Des Voeux Road, King's Road, Queen's Road.

### Tunnels

Hong Kong Island is connected to the Kowloon Peninsula on the mainland by two road-only tunnels (the Cross-Harbour Tunnel and the Western Harbour Crossing), three MTR railway tunnels (East Rail line, Tsuen Wan line and Tung Chung line/Airport Express) and one combined road and MTR rail link tunnel (Eastern Harbour Crossing, containing the Tseung Kwan O line and road traffic in separate parallel conduits).
Besides these harbour crossing tunnels, Hong Kong Island also has two tunnels travelling across the island itself, the Aberdeen Tunnel and Central–Wan Chai Bypass, which were opened in March 1982 and January 2019 respectively.
The Aberdeen Tunnel provides a link from Happy Valley and Wong Chuk Hang, with the toll fee being HK$5.
The Central–Wan Chai Bypass provides a link from Sheung Wan to Wan Chai North and the Eastern Corridor beyond Causeway Bay. It was built as part of the Central and Wan Chai Reclamation and is part of Route 4. The bypass is toll-free.

### Bridges

There are no bridges between the island and Kowloon, although two bridges – the Ap Lei Chau Bridge, a road bridge, and Aberdeen Channel Bridge, part of the South Island line – connect the Hong Kong island to Ap Lei Chau.
The Ap Lei Chau Bridge is a combination of two bridges, built separately in 1980 and 1994. It was built to accommodate the growing population in Ap Lei Chau, which the residents could only access the island by boats prior to the construction of the bridge.

### Central-Mid Levels escalator and walkway system

The Central-Mid Levels escalator and walkway system is the longest outdoor covered escalator system in the world. It was opened in 1993 with the initiative of providing relief to traffic in the Mid-Levels. It travels from Queen's Road Central to Conduit Road, with the total horizontal distance being over 800 m (2,600 ft) and total vertical distance being over 135 m (443 ft). It consists of covered walkways, 16 reversible one-way escalators and 3 reversible one-way travelators. Restaurants, bars and shops can be found alongside the system. Along its use of transporting, it is also a tourist attraction to the many visiting Hong Kong. As of late 2016, around 78,000 pedestrian make their trips using the system.
