Located at the shores of the River Clyde Glasgow is the largest city of Scotland. Glasgow used to be an important place for trade and heavy industry. At the end of the 19th century it was producing more than 50 percent of Britain's tonnage of shipping. After many ups and downs Glasgow’s industry started to decline steeply by the end of the 50s of the last century. But Glasgow successfully managed to reinvent itself. By now it is a most attractive town of art, culture, tourism, finance and business services. There are three buildings belonging to the Science Centre that was opened in 2001: Glasgow Tower, Science Mall and IMAX cinema. Glasgow Tower is not the highest free-rotating tower in the world. Well it was ment to bee so – but is does not really work.
