Possenhofen Castle

Possenhofen Castle rises on the western shore of Lake Starnberg with a square main building, corner towers and parklike grounds extending down to the water. The facade shows plain white walls with rows of windows, while red roofs over the towers reflect Bavarian building style.

Jakob Rosenbusch built the castle in 1536 as a country seat, which was destroyed in the Thirty Years' War and later reconstructed. Duke Maximilian in Bavaria acquired the property in 1834 and expanded it into a ducal summer residence.

The nearby Roseninsel takes its name from the royal gardens Maximilian planted there, serving the family as a private retreat on the lake. The estate was a summer home for the ducal family, where children played along the shore and took boat trips.

The property at Karl-Theodor-Straße 14C has been divided into private condominiums and remains closed to visitors, though the exterior can be viewed from the lakeside path. Public walking paths around the castle along the lake offer glimpses of the surroundings.

After 1920, the building housed in turn a children's home, a hospital and a motorcycle workshop before conversion into apartments. Part of the grounds still features old trees dating from the time when the ducal family lived here.
