Iziko South African Museum & Planetarium
Founded in 1825, this natural history museum houses more than 1½ million scientific specimens, from Stone Age tools to fairly recent finds. It's most popular for its "Whale Well," where life-size casts of enormous marine mammals are suspended over a multi-storied chamber, which leads to displays of marine and terrestrial animals in the old diorama style. International photography exhibits are often on display upstairs, and there is an interesting if creepy section on the fossil remains of prehistoric "mammal-like" reptiles. In the adjoining planetarium, visitors can experience the thrills of a 360-degree multisensory, full-dome theater, where a variety of shows for children and adults play six days a week.
