Tun Mustapha Tower is a 122-metre, 30-story glass tower in Kota Kinabalu, Sabah, Malaysia. It was built in 1976 by Mori Building Company, a Japanese construction firm. The building was formerly named Yayasan Sabah Tower as it housed the Sabah Foundation (Yayasan Sabah), a state-sponsored foundation to promote education and economic development in the state. In 2001, the tower was renamed to honour Tun Datu Mustapha, a former Sabah chief minister and state governor. There is a revolving floor on the 18th floor, which slowly spins to give a complete view of the Likas Bay. It makes one 360 degree rotation per hour. On 20 April 1997, urban climber Alain Robert successfully scaled the building, with government approval, for a fundraiser. He began climbing from the 16th floor and reached the top of the building in just five minutes.
