The Monastery of Santa Maria de Belém, better known as Mosteiro dos Jerónimos, is a Portuguese monastery, built at the end of the 15th century by King Manuel I and was handed over to the Order of São Jerónimo. It is located in the parish of Belém, in the city and municipality of Lisbon. It has, since 2016, the status of National Pantheon.
The culmination of Manueline architecture, this monastery is the most remarkable Portuguese monastic complex of its time and one of the main hall churches in Europe. Its construction began at the beginning of the 16th century and lasted for a hundred years, having been directed by a remarkable group of architects/masters of works (note the decisive role of João de Castilho).
The Jerónimos Monastery has been classified as a National Monument since 1907 and, in 1983, it was classified as a World Heritage Site by UNESCO, together with the Torre de Belém. On July 7, 2007 it was elected as one of the seven wonders of Portugal. Closely linked to the Portuguese Royal House and the epic Discoveries, the Jerónimos Monastery was, from an early age, “internalized as one of the symbols of the nation”.
