This Bavarian medieval castle built in 1903, with a tall round turret, chimneys, balconies, and Greek-style columns, was originally a Russian aristocrat's villa but was later taken over by the German governor general as a fishing retreat. In 1946, Chiang Kai-shek secretly retreated here to plan the Kuomintang's next moves. These days, the villa, a big hit with wedding parties, can't exactly be called quiet or relaxing. Climbing to the top affords the visitor a grand view of the surrounding Ba Da Guan area.
