The Pena Palace (Portuguese: Palácio da Pena) is a Romanticist castle in São Pedro de Penaferrim, in the municipality of Sintra, on the Portuguese Riviera. The castle stands on the top of a hill in the Sintra Mountains 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. All of that being said, this one was kind of a bust for us. We were told that the interior of the castle wasn't worth the hours of waiting, so just get tickets for the grounds so we can see the outside of the castle. Evidently things have changed so the tickets we had only let us see the grounds, but not get anywhere near the castle itself. Live and Learn!
