Government office in the Strand, London, built 1775. It is used by the Inland Revenue, the Principal Probate Registry, where wills are kept, and by the University of London. Somerset House is also the new home of the Courtauld Collection of paintings. The river facade was designed by William Chambers. The General Register Office (births, marriages, and deaths), formerly at Somerset House, was merged with the Government Social Survey Department as the Office of Population Censuses and Surveys in 1970, and transferred to St Catherine's House, also in the Strand.
