Schloss Ehrenfels, Baroque castle in Hayingen, Germany

Schloss Ehrenfels is a Baroque former summer residence of Zwiefalten Abbey, built 1735–1740 under Abbot Augustin Stegmüller above a 66-metre cellar cut into rock. The abbey's coat of arms remains above the courtyard door, and worn stone floors in the ground floor mark the monks' former chapel and kitchen. A free staircase leads to the Baroque park.

Abbot Augustin Stegmüller of Zwiefalten had the castle built between 1735 and 1740 as a summer residence, replacing a former monastery and farmstead. In 1803, during the secularisation of Zwiefalten, it passed to Duke Friedrich II of Württemberg, who gave it to minister Philipp Christian Friedrich Freiherr von Normann for his negotiations with Napoleon. Normann, later Count Normann-Ehrenfels, removed the altar and added a flight of steps to the Baroque park.

Coats of arms displayed throughout the castle tell the story of its different owners across centuries. These symbols are visible especially at the entrance and near the Baroque staircases, where they continue to speak of the place's past to visitors today.

The property offers parking facilities and accessible entry for visitors with mobility limitations. The rooms accommodate smaller gatherings, so it is advisable to check in advance whether the place is open to public visits on your intended day.

The 66-metre cellar beneath the castle was cut into the rock as the Zwiefalten monastery's storage vault, because the marshy ground at Zwiefalten itself allowed no cellar to be dug. The abbot's coat of arms still hangs above the courtyard doorway.
