Congress House is the headquarters of the Trades Union Congress (TUC), a British organisation that represents most of the UK's trade unions. In 1948, David du Roi Aberdeen won an architectural competition to design the new TUC headquarters building in Great Russell Street, London. Staff began to move into the offices in 1956 and the building was officially opened in 1958. The building is Grade II* listed. The front of the building is dominated by a bronze sculpture by Bernard Meadows representing the spirit of trade unionism with the strong helping the weak. * *
