Burgruine Kraftstein

Mühlheim an der Donau, Germany, Germany

---

Burgruine Kraftstein is the remains of a medieval Höhenburg perched on a small rocky spur about 5 kilometers northwest of the town of Mühlheim an der Donau in the Tuttlingen district of Baden‑Württemberg, Germany, overlooking the Ursental side valley of the Donau.

The castle was built around 1100–1200 by the noble families of Wartenberg and Dürbheim and later became a possession of the town, serving as a local stronghold for several centuries before it fell into ruin. Today only the lower part of the once‑tall residential tower, with a base roughly 10 by 15 meters and thick stone walls, is still visible, standing in a steep, forested hanglance above the valley, while the surrounding area has been cleared and partially restored so that visitors can explore the compact ruin and enjoy scenic views of the Donau region from the site.
