The Solar Pyramid was a proposed sculpture originally scheduled to open in June 2003 in the United Kingdom. The pyramid was to have been the UK's largest sculpture. It was also intended to become the UK’s largest artwork, the world’s biggest functioning timepiece, and the world's largest sundial. The sculpture, originally planned for a site in Derbyshire, and later one in Dorset, failed to attract sufficient finance or public support to be constructed. The design consisted of three towers, or gnomons, which leaned together to create an illusion of a pyramid.
