The Blitz was a German bombing offensive against Britain in 1940 and 1941, during the Second World War.
 The term was first used by the British press as an abbreviation of "Blitzkrieg" (lightning war).
 The Germans conducted mass air attacks against industrial targets, towns and cities, beginning with raids on London towards the end of the Battle of Britain in 1940, a battle for daylight air superiority between the "Luftwaffe" and the Royal Air Force over the United Kingdom.
 By September 1940, the "Luftwaffe" had failed and the German air fleets ("Luftflotten") were ordered to attack London, to draw RAF Fighter Command into a battle of annihilation.
 Adolf Hitler and "Reichsmarschall" Hermann Göring, commander-in-chief of the "Luftwaffe", ordered the new policy on 6 September 1940.
 From 7 September 1940, London was systematically bombed by the "Luftwaffe" for 56 out of the following 57 days and nights.
 Most notable was a large daylight attack against London on 15 September.
St Michael and All Angels Church, Beckton Road, was a Church of England church in East Ham, east London.
 It opened as a mission of St Mary Magdalene's Church, East Ham in 1883 and immediately rebuilt after burning down three years later.
 A permanent church was built on a new site around 1906, funded by the Gas Light and Coke Company.
 A new mission district was formed for it about 1922, but the church was not rebuilt after bombing in 1941 during the London Blitz and ultimately the district was dissolved in 1952, to be merged back into St Mary's parish.
 St Michael's had also founded two mission churches of its own, St Mark's, Ferndale Street (c.1890) and St Andrew's, Roman Road (1934) - these both closed in 1952 when the district was dissolved.
Altab Ali Park is a small park on Adler Street, White Church Lane and Whitechapel Road, London E1.
 Formerly known as St. Mary's Park, it is the site of the old 14th-century white church, St. Mary Matfelon, from which the area of Whitechapel gets its name.
 St Mary's was heavily bombed during The Blitz in 1940, all that remains of the old church is the floor plan and a few graves.
 Included among those buried on the site are Richard Parker, Richard Brandon, Sir John Cass, and "Sir" Jeffrey Dunstan, "Mayor of Garratt".
St Mary Magdalene Church is an Anglican church on Holloway Road in north London.
 It is located in St Mary Magdalene Gardens opposite Islington Central Library.
 St Mary Magdalene is part of the Parish of Hope Church Islington (previously the Parish of St Mary Magdalene and St David).
 In 2013 its sister church St David's on Westbourne road was reopened so St Mary Magdalene now functions as one of two worship sites of the Parish, with a single leadership and a staff team.
 The early 19th century building accommodates the activities of the church congregation, including church services, a winter night shelter, 'Mini Mags' – a toddlers group, and provides spaces to other users.
 Baptisms and confirmations, marriages and funerals are regularly held here.
The Pleasance is a street just outside the Old Town of Edinburgh, Scotland, a remnant of the town walls flanking the west side of the street between Drummond Street and the Cowgate.
 Historically, the street was one of the main routes into Edinburgh from the south, meeting St Mary's Wynd (now St Mary's Street) at St Mary's Wynd Port, one of the gateways of the town walls.
 The name derives from the Scots "plesance", meaning a park or garden.
 It first appears in 1507 as the name of a nearby house and was later transferred to the street and then the suburb which was part of the regality of the Canongate.
 The derivation of the name from a nunnery of St Mary of Placentia, often mentioned in histories of Edinburgh, is an invention by William Maitland in his 1753 "History of Edinburgh".
 The street is largely residential, although the University of Edinburgh owns property in the area.
The Church of St Mary on the Rock or St Mary's Collegiate Church, was a secular college of priests based on the seaward side of St Andrews Cathedral, St Andrews, just beyond the precinct walls.
 It is known by a variety of other names, such as St Mary of the Culdees, Kirkheugh and Church of St Mary of Kilrymont.
The first bombing of Dublin in World War II occurred early on the morning of 2 January 1941, when German bombs were dropped on the Terenure area of south Dublin.
 This was followed, early on the following morning of 3 January 1941, by further German bombing of houses on Donore Terrace in the South Circular Road area of south Dublin.
 A number of people were injured, but no one was killed in these bombings.
 Later that year, on 31 May 1941, four German bombs fell in north Dublin, one damaging Áras an Uachtaráin but with the greatest impact in the North Strand area, killing 28 people.
 However, the first bombing of the Republic of Ireland had taken place several months earlier, on 26 August 1940, when the German Luftwaffe bombed Campile, County Wexford, killing three people.
St Mary Axe was a mediaeval church in the City of London.
 Its full name was "St Mary, St Ursula and her 11,000 Virgins", and it was also sometimes referred to as "St Mary Pellipar".
 Its common name (also "St Mary" [or "Marie"] "at the Axe") derives from the sign of an axe over the east end of the church.
 The church's patrons were the Skinners' Company.
Holy Trinity Church was a Church of England parish church in Canning Town, east London.
 Its origins were in the Plaistow and Victoria Docks Mission, set up to serve the growing area of Hallsville by the vicar of St Mary's Church, Plaistow and Antonio Brady.
 It initially worshipped in the National School on Barking Road until the permanent church opened in 1867, with a parish formed for it the following year by parts of St Mary's and All Saints.
 Its advowson was initially vested in the bishop, but transferred to the Lord Chancellor in 1886 to allow the benefice of Holy Trinity to be supplemented from revenues from All Hallows Church, London Wall.
 It was badly damaged by bombing in 1941 but re-opened the following year.
 In 1948 it was closed and later bought by West Ham Borough Council, which demolished it and built flats on the site.
 A war damage payment to it instead went towards the construction of St Erkenwald's Church, Barking, opened in 1954.
 The parish survived until 1961, when it was mostly merged into that of St Matthias' Church, Canning Town, whose vicar had administered it in the interim, though some of it passed to St Cedd's Church, Canning Town.
The Bombing of Warsaw in World War II refers to the bombing campaign of Warsaw by the German Luftwaffe during the siege of Warsaw in the Invasion of Poland in 1939.
 It also may refer to German bombing raids during the Warsaw Uprising in 1944.
 During the course of the war approximately 84% of the city was destroyed due to German mass bombings, heavy artillery fire and a planned demolition campaign.
