Mosteiro dos Jeronimos (Jeronimos Monastery), Lisbon. The church and the monastery, like the nearby Torre de Belém and Padrão dos Descobrimentos, symbolise the Portuguese Age of Discovery and are among the main tourist attractions of Lisbon. In 1983, UNESCO formally designated the Monastery of the Hieronymites and Tower of Belém as a World Heritage Site. Construction of the Jeronimos Monastery began in 1501, on the orders of King Manuel I. Chosen as the royal pantheon and financed by the monumental wealth brought back from India, this monumental construction is a brilliant synthesis of European late-Gothic and early renaissance trends.
