The Pena National Palace (Portuguese: Palácio Nacional da Pena) is the oldest palace inspired by European Romanticism. It is located in the civil parish of São Pedro de Penaferrim, municipality of Sintra, Portugal. The palace stands on the top of a hill above the town of Sintra, and on a clear day it can be easily seen from Lisbon and much of its metropolitan area.
It is a national monument and constitutes one of the major expressions of 19th century Romanticism in the world. The palace is a UNESCO World Heritage Site and one of the Seven Wonders of Portugal. It is also used for state occasions by the President of the Portuguese Republic and other government officials.
