It was built in 1976 by Mori Building Company, a Japanese construction firm.

In 2001, the tower was renamed to honour Tun Datu Mustapha, a former Sabah chief minister and state governor.

On 20 April 1997,[3] 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.
