Schloß Neusteußlingen, Medieval castle in Schelklingen, Germany.

Schloss Neusteußlingen is a fortified structure perched on an elevated spur above the Schmiechtal valley, built from stone with features spanning several construction periods. The building combines architectural elements from different eras that reflect its long development over time.

The original Steusslinger fortress underwent partial demolition in 1581 under orders from Duke Ludwig of Württemberg. A new administrative building was subsequently constructed on the same site with a more modern layout.

The castle served as the seat of the Freiherren von Freyberg-Steußlingen family and shaped regional life as an administrative center. Its role as a longstanding noble residence marked its importance to the local population.

The castle is in private ownership and cannot be visited; there is no access to the buildings or the grounds. The site lies on a spur above the Schmiechtal valley near Schelklingen, roughly 11 km from Ehingen, at about 650 m elevation. Views of the surrounding valley are possible from public paths in the area.

Publisher Eugen Nübling purchased the ruins in 1897 and transformed them into a private residence. His renovation work combined elements from both the original fortress and the older fortification system.
