The island’s northern end is dominated by the massive Fort of São Sebastião, which is the oldest complete fort still standing in sub-Saharan Africa. Construction began in 1558, and about 50 years later the final stones were laid. Just beyond the fort, at the island’s tip and accessed via the fort entrance, is the tiny Chapel of Nossa Senhora de Baluarte . Built in 1522, it’s considered to be the oldest European building in the southern hemisphere and one of the best examples of Manueline vaulted architecture in Mozambique. At the southern end of the island, overlooking Makuti Town and the fishing port, is the large (and no longer used) Church of Santo António . Nearby is a cemetery with Christian, Muslim and Hindu graves.
