Sonnenberg Castle

Sonnenberg Castle is a medieval fortress situated on the Immenberg slopes near Stettfurt at approximately 649 meters elevation. The structure includes fortified walls, residential areas, and houses a restaurant where visitors can experience the building's interior spaces.

The castle was first documented in 1242 and suffered destruction during the Appenzell Wars in 1407. The Landenberg family subsequently rebuilt it, ensuring its survival as a structure in the landscape.

Today visitors come here to dine at the on-site restaurant while experiencing the medieval setting firsthand. This living use of the castle connects people with its past in a direct and everyday way.

The castle can be reached at Sonnenberg 1 in Stettfurt, where the restaurant is also located. Visitors should wear sturdy shoes due to the sloped terrain and elevated position of the site.

The castle operates as a restaurant, which means much of the building remains closed to casual visitors. This creates an unusual experience where diners get glimpses of medieval spaces while those outside can only view the exterior fortifications.
