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 Art Gallery houses the art collection of the City of London, England. The museum is located in the Moorgate area of the City of London. It is a stone building in a semi-Gothic style intended to be sympathetic to the historic Guildhall, which is adjacent and to which it is connected internally.

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.

Basinghall Street (sometimes written as "Bassinghall") is a street in the City of London, England. It lies chiefly in the ward of Bassishaw (originally the street and the courts and passages leading off from it) with the southern end in Cheap and Coleman Street wards. The street and ward are named after the Bassing family, who built a hall house here in the 13th century and who were given certain privileges by the King. The Guildhall, of a few separate "wings" has entrances around Guildhall Yard abutting, as well as another street, the west of the street; and the allied Mayor's and City of London Court forming "Guildhall Buildings" and its tree-lined walkways. The street was a direct link between Gresham Street, south then is cut off by building, most directly, from the road aspect of London Wall north. The latter is accessed from the street's north-western spur and Aldermanbury Square and footway by Brewers Hall, or longer north-eastern spur which is named Bassinghall Avenue which hosts the verdant Girdlers' Company mansion and then a few metres of Coleman Street. Despite this westward change, the meandering street has kept the same length: of about 270 metres. St Michael Bassishaw was a church on the street demolished in 1900.

Guildhall is a municipal building in the Moorgate area of the City of London, England. It is off Gresham and Basinghall streets, in the wards of Bassishaw and Cheap. The building has been used as a town hall for several hundred years, and is still the ceremonial and administrative centre of the City of London and its Corporation. It should not be confused with London's City Hall, the administrative centre for Greater London. The term "Guildhall" refers both to the whole building and to its main room, which is a medieval great hall. The nearest London Underground stations are Bank, St Paul's and Moorgate. It is a Grade I-listed building.

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.

St Olave's Church, Old Jewry, sometimes known as Upwell Old Jewry, was a church in the City of London located between the street called Old Jewry and Ironmonger Lane. Destroyed in the Great Fire of London in 1666, the church was rebuilt by the office of Sir Christopher Wren. The church was demolished in 1887, except for the tower and west wall, which remain today.

Ironmonger Lane is a narrow one-way street in the City of London running southbound between Gresham Street and Cheapside. Ironmonger Lane has maintained the same name since at least the 12th century when it was recorded as Ismongerelane; "isen" was an old form of the word "iron". Its name indicates that it was the once the location of ironmongers; but by the end of the 16th century, when John Stow was writing his Survey of London, the ironmongers of Ironmonger Lane and Old Jewry had moved to Thames Street.Until the Great Fire of London in 1666, Ironmonger Lane was one of only two accesses to the Guildhall (the other being Lawrence Lane), a matter which made the travel of dignitaries difficult as two vehicles could not pass each other. The problem was alleviated after the fire when King Street was added by Christopher Wren to provide an additional access to Cheapside.Thomas Becket is said to have been born on the corner of Cheapside and Ironmonger Lane. The livery hall of the Worshipful Company of Mercers may lie on the same spot; it is a relatively modern building, the first hall having been destroyed in the Great Fire and a second in the Blitz. In the interwar-period, Ironmonger Lane was the seat of several cartels e.g. of the European Rail Makers Association ERMA. The nearest London Underground/Docklands Light Railway station is Bank. The closest mainline railway stations are Cannon Street and Moorgate.

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 original statue of 1751 now stands in the Guildhall in London. There is also a fibreglass replica at the School of Art, Architecture and Design at London Metropolitan University in Jewry Street, installed in 1998.

St Lawrence Jewry next Guildhall is a Church of England guild church in the City of London on Gresham Street, next to Guildhall. It was destroyed in the Great Fire of London in 1666, and rebuilt to the designs of Sir Christopher Wren. It is the official church of the Lord Mayor of London.
