Fodor's Expert Review Schloss Schwetzingen

This formal 18th-century palace was constructed as a summer residence by the Palatinate electors. It is a noble rose-color building, imposing and harmonious; a highlight is the rococo theater in one wing. The extensive park blends formal French and informal English styles, with neatly bordered gravel walks trailing off into the dark woodland. Fun touches include an exotic mosque—complete with minarets and a shimmering pool (although they got a little confused and gave the building a very baroque portal)—and the "classical ruin" that was de rigueur in this period. The palace interior can only be visited by tour. It's one of Germany's many UNESCO World Heritage sites.
