The Park and National Palace of Pena in Sintra, Portugal, was the visionary creation and summer residence of King Ferdinand II (the "Artist-King") and his wife, Queen Maria II. Built in the 19th century on the ruins of a 16th-century Hieronymite monastery, it served as a private retreat for the Portuguese Royal Family. After the death of Queen Maria II in 1853, Ferdinand lived there with his second wife, Elise Hensler, the Countess of Edla, who significantly influenced the design of the surrounding park and the chalet that bears her name. The palace remained a royal residence until 1910, when the Portuguese monarchy was overthrown during the Republican Revolution. The last royal to spend significant time there was Queen Amélie of Orléans, who left for exile from the nearby Praia das Maçãs. Today, the palace is preserved exactly as it was when the royals lived there, with rooms like the "Great Hall" and the "Royal Dining Room" still featuring the original furniture and personal artifacts, offering a rare glimpse into the eclectic and romantic lifestyle of the 19th-century Portuguese monarchy.
