Rothehof, Medieval castle and archaeological site in Wolfsburg, Germany.

Rothehof is a vanished medieval motte-and-bailey castle in the Wolfsburg city forest, near the Stemmelriede stream. Its remains consist of a roughly 3 m high, 12 m × 15 m mound with a 5 m × 5 m depression on top, where wall foundations of a wooden or stone residential tower are still visible. A surrounding rampart, once topped by palisades, and the stream on one side completed the defences.

The small motte-and-bailey castle was built around 1200 and first documented in 1304, when Kunigunde von Bartensleben received Rothehof with its appurtenances. It served as the fortified residence of the Rothehof line of the von Bartensleben, who rose from ministerials to lower nobility in the 13th and 14th centuries. Its likely task was guarding the trade route through the Aller valley. Sherds ending in the 15th century show the site was abandoned in favour of Wolfsburg and Burg Neuhaus.

The site is a vanished motte, a medieval tower-mound castle, not a standing building. Its name comes from the Rothehof branch of the von Bartensleben family, who held the Rothen Hoff by 1362. A stone tablet placed by the Wolfsburger Verein für Heimatpflege marks the spot in the forest.

The site lies in the Wolfsburg city forest near the Stemmelriede stream, reachable on foot; a nearby street is named Burgwall after the medieval earthwork. The turf mound and its surrounding wall survive in the woods, so sturdy footwear helps on uneven ground. A stone plaque set up by the Wolfsburg heritage association marks the spot.

The castle mound still rises about 3 m high and measures roughly 12 by 15 m, with a 5 by 5 m hollow on top that looks like a former cellar. Wall foundations survive at its edges, where a wooden or stone residential tower once stood. A local heritage association placed a stone plaque at the site to recall the castle.
