The Palazzo dello Spagnolo in Naples is a cool Rococo-style palace known for its fancy staircase. Built in 1738 by the Marchese di Poppano, it's got this octagonal courtyard and some seriously intricate stucco work inside. The top floor was added later, and the place even has a nickname - "the Spaniard" - because of a dude named Tommaso Atienza who bought some apartments there. Despite looking a bit rundown now, those arch-filled staircases still give off major dramatic vibes.
