This image is flopped. Mansion House should be on the left of the sculpture seen from the back. The equestrian statue of the Duke of Wellington stands in front of the Exchange. Cast from the metal of guns taken from the French by Francis Chantry, 1844.

Mansion House is a rare surviving Georgian town palace in London. It is the official residence of the Lord Mayor of London. Dance's designs of 1735 show the influence of Colen Campbell's Wanstead House, Essex, particularly in the great hexastyle portico approached by a double flight of steps in two stages (now reduced to one). The internal arrangement around a courtyard (later filled in) included a ballroom lit by a clerestory and an 'Egyptian Hall', which took its name from a Vitruvian Roman prototype earlier drawn upon by Richard Boyle, 3rd Earl of Burlington, in his York Assembly Rooms of 1731-1732.
