The Shard, also referred to as the Shard London Bridge and formerly London Bridge Tower, is a 72-storey mixed-use development supertall pyramid-shaped skyscraper, designed by the Italian architect Renzo Piano, in Southwark, London, that forms part of The Shard Quarter development. Standing 309.6 metres high, The Shard is the tallest building in the United Kingdom, the seventh-tallest building in Europe, and the second-tallest outside Russia behind the Varso Tower in Warsaw, which beats the Shard by less than half a metre. The Shard replaced Southwark Towers, a 24-storey office block built on the site in 1975.
