There's no doubt that the Queen's Royal College is heritage from colonial times. Together with a few other architectural gems, this is a good reason to walk up to the Queen's Park Savannah and head up the west side of it to go to the zoo and the botanical gardens on the northern side.

Don't bother trying to go straight across the park. Sections are often wet/muddy, and the heat out on the open lawn is best avoided by following the shade offered by the trees along the road.
