According to the plaque on the wall, this belvedere and the "Japonica Walk" in front of it lie on the main axis around which the campus of the University of Cape Town was planned.
The motorway cuts Upper and Middle campus in two, and you can see its crash barriers above the belvedere. The beautiful buildings of the Upper Campus can just be seen in the trees below Devil's Peak. (The other campus, Hiddingh Campus, is in the city of Cape Town.)
