Guildhall is a building in the City of London, off Gresham and Basinghall streets, in the wards of Bassishaw and Cheap. It 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. The term Guildhall refers both to the whole building and to its main room, which is a medieval great hall. Guildhall complex houses the offices of the City of London Corporation and various public facilities. The building is traditionally referred to as Guildhall, never “the” Guildhall. Guildhall should not be confused with London City Hall, which is the administrative centre for Greater London, of which the City of London is only a geographically small part. The nearest London Underground stations are Bank, St Paul’s and Moorgate.
