Belém is famous as the place from which many of the great Portuguese explorers set off on their voyages of discovery. In particular, it is the place from which Vasco da Gama departed for India in 1497 and Pedro Álvares Cabral departed for Brazil in 1499. It is also a former royal residence and features the 17th – 18th-century Belém Palace, a former royal residence now occupied by the President of Portugal, and the Ajuda Palace, begun in 1802 but never completed.
