Citypoint is a building located on Ropemaker Street on the northern fringe of the City of London, the main financial district and historic nucleus of London. Originally named Britannic House, Citypoint was built in 1967 as a 35-storey, 122-metre tall headquarters for British Petroleum, becoming the first building in the City of London area to exceed the height of St Paul's Cathedral. The designers were F. Milton Cashmore and H. N. W. Grosvenor.
