Schloss Plon crowns a wooded hilltop overlooking the Grosser Plon See, the largest of the many lakes in the Holstein Switzerland region, and is the largest castle in Schleswig-Holstein. Built between 1633 and 1688 for Duke Joachim Ernst, the Baroque palace later served as a summer residence for the Prussian royal family, including the future Kaiser Wilhelm II, who spent part of his youth there. Today the building houses a private international boarding school, which limits general visitor access to a museum wing covering the palace's ducal and Prussian royal history, along with select state rooms opened to the public. The grounds and terraced gardens surrounding the palace remain freely accessible and offer sweeping views over the lake and the town of Plon below, considered among the best panoramas in the Holstein Switzerland lake district. A visit to the museum rooms takes about an hour; walking the surrounding gardens and viewpoints adds another 30 to 45 minutes. Because the palace operates as a working school, visitor access to interior rooms is more limited than at other Schleswig-Holstein castles, and weekday mornings offer the best chance of an uncrowded visit given the restricted opening pattern.
