Guildhall, London in the context of "Gresham Street"

A guildhall, also known as a guild hall or guild house, is a historical building originally used for tax collecting by municipalities or merchants in Europe, with many surviving today in Great Britain and the Low Countries. These buildings commonly become town halls and in some cases museums while retaining their original names.

The City of London Corporation, officially and legally the Mayor and Commonalty and Citizens of the City of London, is the local authority of the City of London, the historic centre of London and the location of much of the United Kingdom's financial sector.

In 2006, the name was changed from Corporation of London to distinguish the body governing the City of London from the Greater London Authority, the regional government of the larger Greater London administrative area. It is a corporation in the sense of being a municipal corporation rather than a company; it is deemed to be the citizens and other eligible parties acting as one corporate body to manage the City's affairs. The corporation is based at the Guildhall.

London Museum (known from 1976 to 2024 as the Museum of London) is a museum in London, covering the history of the city from prehistoric to modern times, with a particular focus on social history. The Museum of London was formed in 1976 by amalgamating the collection previously held by the City Corporation at the Guildhall Museum (founded in 1826) and that of the London Museum (founded in 1911). From 1976 to 2022, its main site was in the City of London on London Wall, close to the Barbican Centre, part of the Barbican complex of buildings created in the 1960s and 1970s to redevelop a bomb-damaged area of the city. In 2015, the museum revealed plans to move to the General Market Building at the nearby Smithfield site. Reasons for the proposed move included the claim that the current site was difficult for visitors to find, and that by expanding, from 17,000 square metres to 27,000, a greater proportion of the museum's collection could be placed on display. In December 2022, the museum permanently closed its site at London Wall in preparation for reopening in 2026 at Smithfield Market. The museum changed its name and branding to "London Museum" in July 2024 in advance of the move.

The museum has the largest urban history collection in the world, with more than six million objects. It is primarily concerned with the social history of London and its inhabitants throughout time. Its collections include archaeological material, such as flint handaxes from the prehistoric Thames Valley, marble statues from a Roman temple called the London Mithraeum, and a cache of Elizabethan and Jacobean jewellery called the Cheapside Hoard. Its modern collections include large amounts of decorative objects, clothing and costumes, paintings, prints and drawings, social history objects, and oral histories. The museum continues to collect contemporary objects, such as the Whitechapel fatberg and the Trump baby blimp.
