Guildhall, London

The Lord Mayor's Show is one of the best-known annual events in London as well as one of the longest-established, dating back to the 13th century. A new lord mayor is appointed every year, and the public parade that takes place as his or her inauguration ceremony reflects that this was once one of the most prominent offices in England. The show is named after the Lord Mayor of the City of London, a city and ceremonial county within Greater London and the historic centre of the wider metropolis, which is distinct from the Mayor of London, the elected head of the Greater London Authority (a position which has existed only since 2000). The City is London's main financial district, widely known informally as 'the Square Mile'. The Lord Mayor's Show is centred on a street parade, which in its modern form is a light-hearted combination of traditional British pageantry and elements of carnival. On the day after being sworn in, the Lord Mayor and several others participate in a procession from Guildhall, via Mansion House and St Paul's Cathedral, in the heart of the City of London, to the Royal Courts of Justice on the edge of the City of Westminster, where the new Lord Mayor swears allegiance to the Crown. Until 1882, the procession went to Westminster Hall.

The statue of John Cass is a lead figure by Louis-François Roubiliac of John Cass (1661–1718), the English merchant and Member of Parliament.

The visible remains of an amphitheatre constructed during Roman London lie beneath the Guildhall Art Gallery complex in the City of London. Some of these remains are displayed in situ in a room in the basement of the art gallery. Discovered in 1988, the site is now a scheduled monument. London's first Roman amphitheatre was built in AD 70 from wood, but was renovated in the early 2nd century with tiled entrances and rag-stone walls. The amphitheatre was used for various public events such as gladiator games, entertaining soldiers and the public with animal fighting and public execution of criminals, as well as religious activities. After the ancient Romans left in the 4th century, the amphitheatre lay derelict for hundreds of years. In the 11th century the area was reoccupied and by the 12th century the first London Guildhall was built next to it, which survives despite the Great Fire of London and The Blitz.

The Guildhall Library is a public reference library specialising in subjects relevant to London. It is administered by the Corporation of London, the government of the City of London, which is the historical heart of London, England. The library was founded in the 1420s under the terms of the will of Lord Mayor Dick Whittington. Many volumes in store rooms were lost due to bombing in World War Two. The library was originally housed in the Old Library at the Guildhall, and moved to modern premises elsewhere in the Guildhall complex in the 1970s.

The statue of Margaret Thatcher in the Guildhall, London, is a marble sculpture of Margaret Thatcher. It was commissioned in 1998 from the sculptor Neil Simmons by the Speaker's Advisory Committee on Works of Art; paid for by an anonymous donor, it was intended for a plinth among statues of former Prime Ministers of the United Kingdom in the Members' Lobby of the House of Commons. However as the House did not permit a statue to be erected there during its subject's lifetime, the work had been temporarily housed in Guildhall. It was unveiled there by Lady Thatcher in February 2002.

Bassishaw is a ward in the City of London. Small, it is bounded by wards: Coleman Street, east; Cheap, south; Cripplegate, north; Aldersgate, west. It first consisted of Basinghall Street with the courts and short side streets off it, but since a boundary review in 2003 (after which the ward expanded into Cripplegate Within) it extends to streets further west, including Aldermanbury, Wood Street, and, to the north, part of London Wall and St Alphage Garden. The ward was historically the City's smallest.
