Mansion House is the official residence of the Lord Mayor of London. It is used for some of the City of London's official functions, including an annual dinner, hosted by the Lord Mayor, at which the Chancellor of the Exchequer customarily gives a speech - his "Mansion House Speech" - about the state of the British economy. The Guildhall is another venue used for important City functions. It is a Grade I Listed Building.
Mansion House is home to The Harold Samuel Collection of Dutch and Flemish Seventeenth Century Paintings, described as "the finest collection of such works to be formed in Britain this century" (Sutton 1992). It consists of 84 paintings and includes some outstanding works by artists including Hendrick Avercamp, Gerard Ter Borch, Pieter Claesz, Aelbert Cuyp, Frans Hals, Pieter de Hooch, Jacob van Ruisdael, Jan Steen, David Teniers the Younger and Willem van de Velde.
Mansion House is not open to the public except for guided group tours. Tours are first come/first served and limited to 40 per group.
