On 7 October 1983, the University of Cape Town's Groote Schuur (translated as "big barn") Campus was declared a national monument.
Originally, in 1829, South African College (later renamed to University of Cape Town) trained students in a building in Long Street. In 1841 they moved to Government Avenue, before finally taking occupation of the Groote Schuur campus in 1928.
Today, the buildings remind me of those old English school buildings that you'd expect to find Harry Potter frequenting. The campus is definitely worth a visit, so if you have some time on your hands to walk around and observe students in their natural habitat, make a turn past the Groote Schuur Campus - here's a map to this exact spot. :)
