The Jerónimos Monastery has proclaimed a UNESCO World Heritage Site in 1983. This notable 16th-century work of architecture became part of Portuguese identity and culture. The Jerónimos Monastery is a National Monument and was classified as a UNESCO World Heritage Site in 1983. King Manuel, I built a large monastery near the location where the Infante D. Henrique ordered a church to be built in the mid-15th century by invocation of St. Mary of Belém. To immortalize the memory of the Infante, for his intense devotion to Our Lady and faith in St. Jerome, in 1496 King Manuel I decided to found the Monastery of St. Mary of Belém, near the city of Lisbon, next to the Tagus River. Donated to the monks of the Order of St. Jerome, today it is commonly known as the Jerónimos Monastery. A pantheon of the Avis-Beja Dynasty, in the 19th century the church became the sepulcher for heroes and poets: Vasco da Gama and Luís de Camões. A notable work of architecture, it became part of Portuguese identity and culture.
