David Hamilton's 1830s classical office building on Queen Street in Glasgow. In Hamilton's design, you can see not only the elements which would go on to be used so successfully a generation later by Alexander 'Greek' Thomson, but also those used in the Modern Classical architecture of the 1930s by the likes of James Miller.
A plaque marking the birthplace of Charles Rennie MacKintosh, probably Glasgow's most famous architect, in the Townhead area of the city in June 1868. In the 1890s, MacKintosh returned to the area to design the Saint Martyr's school which would have been visible from the tenement where he was born. While the school remains, the tenement itself is now long gone.
Another of A.B. McDonald's masterpieces, this time in the form of the 1890s Renaissance style People's Palace on Glasgow Green.
McDonald is one of a whole slew of talented architects who did as much (if not more) than Thomson and MacKintosh to shape how Glasgow looks today, but who remain poorly known and overlook by many.
