House & Family History: Montagu House, Whitehall, was an mid-19th century exuberant French-style chateau designed by William Burn. It was one of the last great houses to be built in London and one of the largest, costing the enormous amount of £100,000 (equivalent to approximately £139 million in 2017 inflation-adjusted values). During World War I the House was taken over by the government for use as offices. Montagu House was demolished between 1949 and 1950; its site is today occupied by the Ministry of Defence building in Whitehall.

Collections: Montagu House was home to a large part of the Buccleuch Collection, including canvases by Rembrandt and Rubens and the finest collection of miniatures in Britain.
