 From the early 1990s, Glasgow City Council and its successor, the Glasgow Housing Association, have run a programme of demolishing the worst of the residential tower blocks, including Basil Spence's Gorbals blocks in 1993.The current tallest structure in Glasgow at 127 metres (417 ft), is the Glasgow Tower within the Glasgow Science Centre, however as this is an observation tower - not strictly speaking a building, then the 26-storey Balgrayhill tower blocks in Springburn area claim the title.The tallest building ever to have stood in Glasgow was the 91.44m Tait Tower in Bellahouston, built for the Empire Exhibition of 1938, but pulled down the following year.
