London - County Hall

County Hall, a nine-story building with more than 1,500 rooms, occupying a 6.5-acre site on the south bank of the Thames at the end of Westminster Bridge, was the headquarters of the Greater London Council until its abolition in 1986, when local government was vested in the London boroughs. The building, in neo-Renaissance style, was begun in 1912 and completed in 1932. New wings were added in 1936 and 1956. There is a good view of County Hall, with its 250 m-long (750ft) facade, centered on a semicircular colonnade, and its steeply pitched roof, from the Victoria Embankment on the opposite side of the Thames.

The building has been renovated and developed, now housing the London Marriott County Hall, London Aquarium,
