One Canada Square

One Canada Square, often referred to simply as Canary Wharf is a skyscraper in Canary Wharf, London. It was the tallest building in the United Kingdom from 1990 to 2010, standing at 770 feet (235 m) above ground level and containing 50 storeys. In late 2010, it was surpassed by The Shard (completed in July 2012) which stands at 309.6 metres (1,016 ft).

One Canada Square was designed by principal architect Cesar Pelli, who based the design and shape mainly on the World Financial Center and the shape of Elizabeth Tower although the developers' (Olympia and York) previous flagship projects, First Canadian Place in Toronto and the Aon Center (formerly the Amoco building) in Chicago are earlier precedents of the building shape and plan form. Unlike the precedents named, the building is clad with durable stainless steel rather than natural stone (which failed prematurely, requiring expensive repairs in several places). One of the predominant features of the building is the pyramid roof which contains a flashing aircraft warning light, a rare feature for buildings in the United Kingdom. The distinctive pyramid pinnacle is at 800 feet (240 m) above sea level.
