Macdonald House, London

Macdonald House, located on Grosvenor Square in Mayfair, London, is a historic building that served as the High Commission of Canada from 1961 to 2014 and was previously the U.S. Embassy from 1938 to 1960. Known for its Neo-Georgian architecture, it became a notable site during World War II, earning the nickname 'Little America.' After being sold in 2013, the building was redeveloped into a luxury residential complex called №1 Grosvenor Square, which retains elements of its original architectural style. This transformation reflects the rich diplomatic history and architectural heritage of the area, making it an interesting site for both tourists and researchers.
