Bartolomeu Dias Museum Complex encompasses historical landmarks and museums in one complex overlooking the beach. It was here that Portuguese explorer Bartolomeu Dias first landed his ship in 1488 and subsequent travelers anchored to gather water and trade with the local Khoi population. In the pleasant walk around the Ethno-botanical Garden and Braille Trail, you can learn about the historic and homeopathic uses of South African plants, or venture towards the beach to view replicas of early Mossel Bay cottages and visit the Mecca-facing graves of early Muslim residents.
The Post Office Tree is the site where Portuguese captain Pedro de Ataide famously left a letter in a shoe under a large tree to document the ordeal he and his shipmates suffered during a bad storm on their voyage. A year later, the letter was found by another Portuguese sailor and thus the first post office in South Africa was born. Today the site itself it not much to write home about, but if you must, you can post your letter in the stone boot after you obtain the proper postage down the street.
