Cape St Blaize Lighthouse was commissioned as a result of the number of vessels using the bay as a safe anchorage and to replenish supplies.
On 3 February 1488, Bartolomeu Dias sailed into Mossel Bay.  When he landed in the bay, he called it Bahia (Aguada) de Sao Bras (“the watering place of St Blaize).  St Blaize is the patron saint of those who suffer from disorders of the ear.
The Bartolomeu Dias Museum Complex in the centre of town consists of various sites of interest.  The most well-known historical feature is the Old Post Office Tree.  The first post office on South African soil was founded at Mossel Bay in 1500, when Pedro de Ataide left a letter of importance in a shoe under a large Milkwood Tree.  Mail is still posted at this ancient Post Office.  Today, it is a National Monument.
