CityPoint (previously known as Britannic House and Britannic Tower) is a skyscraper 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 metres (400 ft) tall headquarters for British Petroleum (now BP), 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. In 1991, British Petroleum moved back to their original headquarters on Finsbury Circus and it was renamed Britannic Tower.
The building was refurbished in 2000, with additional floor space and the height increased to 127 metres (417 ft). The designer for the refurbishment was Sheppard Robson. It was renamed CityPoint after its refurbishment. Its anchor tenant is Simmons & Simmons, a law firm. CityPoint is the fifth-tallest building in the City, after the Heron Tower, Tower 42, the Gherkin, and the Broadgate Tower, but only the 13th-tallest in Greater London.
In August 2005 its owner, Pillar Properties, sold the building for more than £500 million in one of the largest deals ever seen in the City office market. In early 2007, the building was again put on the market, this time for £650 million, and purchased by a private American company called Beacon Capital. At the time it was the most expensive building Sale in the United Kingdom. However, 8 Canada Square at Canary Wharf eclipsed this by some margin just a few months later when it was sold for over £1 billion. A number of other large buildings are being planned on sites nearby. These include a 43-storey, 140 metres (459 ft) residential tower at Milton Court. A 90 metres (295 ft) office tower at Ropemaker Place has also been developed by British Land.
