Belgravia is characterised by grand terraces of white stucco houses, and is focused on Belgrave Square and Eaton Square. It was one of London's most fashionable residential districts from its beginnings. After World War II, some of the largest houses ceased to be used as residences, or townhouses for the country gentry and aristocracy, and were increasingly occupied by embassies, charity headquarters, professional institutions and other businesses. Belgravia has become a relatively quiet district in the heart of London, contrasting with neighbouring districts, which have far more busy shops, large modern office buildings, hotels and entertainment venues. Many embassies are located in the area, especially in Belgrave Square.
