São Tomé is centred on a sixteenth-century cathedral, that was largely rebuilt in the 19th century. Another early building is Fort São Sebastião, built in 1566 and now the São Tomé National Museum. On July 9, 1595, a slave revolt led by Rei Amador took control of the capital; they were subjugated in 1596. In 1599, the Dutch took the city as well as the islands for two days; they re-occupied it in 1641 for a year. The city served as the capital of the Portuguese colony of São Tomé and Príncipe and, from São Tomé and Príncipe's independence in 1975, as capital of the sovereign nation.
