Designed by Charles Rennie Mackintosh, Glasgow School of Art is one of the most influential and significant buildings of the 20thC. As it is still a working art school, Glasgow School of Art can only be visited by guided tour. The tour takes you along the corridors of the School, through the School's collection of original Mackintosh furniture and finishing in one of Mackintosh's celebrated interiors, the Library. Glasgow School of Art was Mackintosh's greatest achievement and it continues to intrigue and inspire visitors from all over the world.
