The castle of Possenhofen, home of Ludwig's favorite cousin, Sissi, stands on the western shore, practically opposite Berg. Local lore says they used to send affectionate messages across the lake to each other. Sissi married the Austrian emperor Franz Joseph I, but spent more than 20 summers in the lakeside castle. The inside of the castle cannot be visited, but there is a nice park around it. The Kaiser Elisabeth Museum (Sissi-Museum) is in the historical Possenhofen railway station (yards from S-Bahn Possenhofen). It is open from around May to mid–October, Fri.–Sun. and entry is €4.
