The Glasgow Tower (initially called the Millennium Tower)is a free-standing tower built in 2001 and forms part of the Glasgow Science Centre. The original architectural design was by the architect Richard Horden, with engineering design by Buro Happold. At 127 metres high, the tower is currently the tallest floored building, and second tallest free-standing structure overall in Scotland (after the Inverkip Power Station chimney), and the largest building in the world which can turn 360 degrees from the ground up. It is shaped like an aerofoil with computer-controlled motors to turn it into the wind in order to reduce wind resistance.
The tower had significant difficulties in its early years due to deficiencies in the Nigerian-made bearings on which the structure revolves.
