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. It was formed in 1976 by amalgamating collections previously held by the City Corporation at the Guildhall Museum and of the London Museum. From 1976 to 2022, its main site was located in the City of London on London Wall, close to the Barbican Centre, as part of the Barbican complex of buildings created in the 1960s and '70s to redevelop a bomb-damaged area of the city. In March 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 as the London Museum.

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 current building dates from the 15th century; however documentary evidence suggests that a guildhall had existed at the site since at least the early 12th century. 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. It is a Grade I-listed building.
