The Archbishop of Magdeburg built the Moritzburg in the late 15th century, after he claimed the city for his archdiocese. The typical late-Gothic fortress, with a dry moat and a sturdy round tower at each of its four corners, is a testament to Halle's early might, which vanished with the Thirty Years' War. Prior to World War II the castle contained a leading gallery of German expressionist paintings, which were ripped from the walls by the Nazis and condemned as "degenerate."
Some of the works are back in place at the Staatliche Galerie Moritzburg, together with some outstanding late-19th- and early-20th-century art. You'll find Rodin's famous sculpture The Kiss here.
