Port Elizabeth / Gqeberha is at Algoa Bay and is the fifth-largest city in South Africa. The pretty old town has retained its rural charm, while modern buildings line the periphery of the city. Climbing the steps up the 52-metre-high bell tower, 'Campanile', is well worth it for the excellent view of the port and the city centre. One of the oldest buildings in the city is on Castle Hill Street, the manse built in 1827 which today houses the Historical Museum. Other sights include: Fort Frederick, Market Square, the Oceanarium with a snake park and tropical hothouse
