The Royal Palace of Madrid is the official residence of the Spanish royal family, but they don't actually live there. It's a massive palace with over 3,400 rooms and tons of history. Built on the site of an old Muslim fortress, it was destroyed by fire in 1734 and rebuilt in a lavish Baroque style. The palace is full of art, including works by famous artists like Goya and Velázquez. Visitors can explore some of the rooms and admire the grand architecture and beautiful decorations.
