The Royal Monastery of Santa Maria of Belém, commonly known as the Jerónimos Monastery because it was intended for the Order of Saint Jerome, has been classified as a National Monument since 1907 and was inscribed on the UNESCO World Heritage List in 1983. The church, which holds religious services and has visiting hours for heritage tours, and the cloister, secularized in the 19th century, form the most visited heritage site in the country.
