The London Bridge Tower,London

Nicknamed The Shard for its eight jagged vertical glass panels, this Renzo Piano–designed tower has offices, residential floors, and a Shangri-La hotel. Controversial since its completion in mid-2012, the 95-story skyscraper—built in an irregular pyramidal shape—is remaking the iconic London skyline. Visitors can take in the city from the viewing gallery and open-air observation deck on the 72nd floor, situated at a dizzying height of 804 feet.
