To visit the 30-storeys and 122 meters high Tun Mustapha Tower (Menara Tun Mustapha), former known as Sabah Foundation Building, is a must when you visit Kota Kinabalu. It is a magnificent building, one of only four hanging structures in the world with a glass façade. It is the tallest building in Borneo and it is the only building in Asia with the unique 72-sided polygon, column-free floors.
