Guy's Hospital is an NHS hospital founded by philanthropist Thomas Guy in 1721, located in the borough of Southwark in central London. It is part of Guy's and St Thomas' NHS Foundation Trust and one of the institutions that comprise the King's Health Partners, an academic health science centre. It is the large teaching hospital of GKT School of Medical Education.
The hospital's Tower Wing (originally known as Guy's Tower) was, when built in 1974, the tallest hospital building in the world, standing at 148.65 metres (487.7Â ft) with 34 floors. The tower was overtaken as the world's tallest healthcare-related building by The Belaire in New York City in 1988. As of June 2019, the Tower Wing, which remains one of the tallest buildings in London, is the world's sixth-tallest hospital building.
