Most of the Portuguese expeditions of the Age of Discovery left Lisbon during the period from the end of the 15th century to the beginning of the 17th century, including Vasco da Gama's expedition to India in 1498. In 1506, 3,000 Jews were massacred in Lisbon. The 16th century was Lisbon's golden era: the city was the European hub of commerce between Africa, India, the Far East and later, Brazil, and acquired great riches by exploiting the trade in spices, slaves, sugar, textiles and other goods. This period saw the rise of the exuberant Manueline style in architecture, which left its mark in many 16th-century monuments (including Lisbon's Belém Tower and Jerónimos Monastery, which were declared UNESCO World Heritage Sites). A description of Lisbon in the 16th century was written by Damião de Góis and published in 1554.
