If it's Baroque, don't fix it, Cesky Krumlov, Czech Republic. Probably the highlight of the castle tour, the Rococo Theater is one of the most well-preserved Baroque theaters in the world.

The trompe l'oeil murals that cover the walls depict a lively life-size masquerade ball with all sorts of splendid comic touches and intriguing situations.

Eight hundred years later, the theater is still used today for special performances.
