Pena Palace was built at the request of King Ferdinand II and his wife, Queen Mary II, between 1842 and 1854. It was erected on a high rock, where at that time there were the ruins of the medieval monastery of Pena, which gave the name to this palace and park complex. The castle and the park served as a summer royal residence until the revolution in 1910 - from the same year it was nationalized and soon a museum was opened there. This amazing castle is a whimsical mixture of different styles - there are Moorish arches and courtyards, Indian domes, as well as Portuguese and German turrets and elements. The Terrace of the Queen offers a magnificent view of the surroundings of Sintra and the unusual palace itself. The interiors of the Pena Palace are no less interesting than its appearance: these are real royal chambers with beautiful frescoes, murals, many paintings, rich furnishings, sculptures, stained glass windows and much more. The extensive Pena Park, located on the slopes of a hill, deserves special attention.
