Pena National Palace, is located on a rocky ridge above Sintra. It's one of several palaces in the Sintra Hills, which were awarded UNESCO World Heritage status as a "cultural landscape" in 1995. The palace, which was built from 1842 to 1854, features a mixture of building styles that range from Moorish to pseudo-medieval. It occupies the site of a Hieronymite monastery that was abandoned after the Great Lisbon Earthquake of 1755 and Portugal's outlawing of religious orders in 1834. The palace is surrounded by Parque da Pena, which offers walking paths, fountains, lakes, follies, and belvederes.
