its Victorian construction; Scott's building is structured upon what was then a cutting-edge riveted iron frame construction, supporting a lightweight wooden-beam roof. The building also forms the second-largest example of Gothic revival architecture in Britain, after the Palace of Westminster. An illustration of the Main Building previously featured on the reverse side of £100 notes issued by Clydesdale Bank. The university's Hunterian Museum resides in the Main Building, and the related Hunterian Gallery is housed in buildings adjacent to the University Library. The latter includes "The Mackintosh House", a rebuilt terraced house designed by, and furnished after, architect Charles Rennie Mackintosh. Even these enlarged premises could not contain the expanding university, which quickly spread across much of Gilmorehill. The 1930s saw the construction of the award-winning round Reading Room (it is now a category-A listed building) and an aggressive program of house purchases, in which the university (fearing the surrounding district of Hillhead was running out of suitable building land) acquired several terraces of Victorian houses and joined them together internally. The departments of Psychology, Computing Science, and most of the Arts Faculty continue to be housed in these terraces. More buildings were built to the west of the Main Building, developing the land between University Avenue and the River Kelvin with natural science buildings and the faculty of medicine. The medical school spread into neighboring Partick and joined with the Western Infirmary. At the eastern flank of the Main Building, the James Watt Engineering Building was completed in 1959. The growth and prosperity of the city, which had originally forced the university's relocation to Hillhead, again proved problematic when more real estate was required. The school of veterinary medicine, which was founded in 1862, moved to a new campus in the leafy surrounds of Garscube Estate, around west of the main campus, in 1954. The university later moved its sports ground and associated facilities to Garscube and also built student halls of residence in both Garscube and Maryhill. The growth of tertiary education, as a result of the Robbins Report in the 1960s, led the university to build numerous modern buildings across Hillhead, including several brutalist concrete blocks: the Mathematics building; the Boyd Orr Building and the Adam Smith building (housing the Faculty of Law, Business and Social Sciences, named after university graduate Adam Smith). Other additions around this time, including the new glass-lined Glasgow University Library, Rankine Building
