Heuberg Castle (Ruin) (Kradolf-Schönenberg)

No written sources from the Middle Ages exist for Heuberg Castle. As no archaeological investigations have been carried out to date, its history can only be speculated upon. The complex was built on a hill about 100 meters long, which was protected at its southern end by a neck ditch. The core apparently consisted of a trapezoidal structure, internally divided, of which walls up to 3 meters high are still preserved today. It remains unclear whether the narrow northern part of the hilltop was also built upon.

The masonry, made of layered, roughly worked boulder stones, is very similar to that of the neighboring Schönenberg Castle. The medieval ownership structures also suggest that both castles belonged to the same lordship and perhaps were the seat of different family branches of the Lords of Schönenberg. These were first mentioned in documents in 1159. It is known that Friedrich von Schönenberg, who participated in the 4th Crusade in 1211, had five sons. Heuberg may have been built for one of them around that time.
