Fort São Caetano is a fort that was built in the 16th century in the present town of Sofala, Mozambique. The fort precisely dates from 1505. Pêro de Anaia assumed the title of Captain-General of Sofala and made Sofala the first Portuguese colony in the region.
He constructed a factory and Fort São Caetano from stone imported from Europe. The stones of the fort were subsequently used to build the Beira Cathedral. São Caetano was the first Portuguese fort in Mozambique.
