Schloss Mageregg, Renaissance castle in Annabichl, Klagenfurt, Austria

Schloss Mageregg is a Renaissance castle in Annabichl featuring five corner towers arranged in a hook-shaped layout. The structure sits within high walls and parkland near the Glan River.

Wolfgang III Mager von Fuchsstatt constructed the castle in 1590 as a fortified residence for his family. Thomas von Moro transformed the building to its present form in 1845.

The Carinthian Hunting Association bought the castle on 27 April 1967 and has run it since as the "Jägerhof Schloss Mageregg", using it for representation. Its regional office has occupied the courtyard outbuilding since 2000. Part of the park serves as a wildlife enclosure.

The castle offers a ground-floor restaurant serving game dishes and upper-floor spaces for events and gatherings. The parkland provides pleasant walking areas, especially for observing the deer on the grounds.

The park is partly used as a game enclosure, and traces of the former moat and a bridge survive on its east side. In the entrance hall, the west wall holds the keystone of builder Wolfgang Mager with a construction inscription dated 1590.
