Possenhofen Castle, Architectural heritage château in Pöcking, Germany.

Possenhofen Castle consists of the Old Castle, a cubic hipped-roof building with four corner towers set crosswise, the New Castle or Horseshoe Building, and the chapel built in 1854 between them, linked by a corridor. The photograph shows a long three-storey main wing with plain pale walls, rows of rectangular windows, and steep red roofs with dormers and chimneys; a shorter wing ends in a square tower with a pyramidal red roof.

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 ducal children called the castle "Possi", and it was their summer home while winters were spent at the Herzog-Max-Palais in Munich. Empress Elisabeth later stayed for 24 years at the nearby Hotel Strauch, renamed Hotel Kaiserin Elisabeth in her honour. The Sissi films were not shot here but at Schloss Fuschl.

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.
