Henneburg, Medieval castle ruin in Stadtprozelten, Germany.

Henneburg is a castle ruin on elevated ground near Stadtprozelten, made up of stone walls and foundations. The site shows typical features of a medieval defensive structure, positioned to overlook the Main valley below.

Timo de Bratselde, bailiff of St. Peter and Alexander in Aschaffenburg from 1127, is considered the founder of the castle district and commissioner of a predecessor of Burg Prozelten, as the Henneburg was first called. Romanesque masonry of the 12th century survives in the great bergfried and the eastern palas. Around 1320 Elisabeth von Wertheim handed the whole estate to the Teutonic Order, which held it for 150 years and carried out the large Gothic rebuilding. In 1484 the Order exchanged it with Mainz for Scheuerberg and Neckarsulm.

The ruins served as a visible symbol of local power and shaped how people organized the landscape for centuries. Today it reminds visitors how these fortifications were central to controlling and structuring the region.

The ruins are reached by hiking trails from Stadtprozelten town center with information panels along the way. Bring sturdy shoes since the climb is steep and the paths can be uneven underfoot.

The name Henneburg probably comes from Georg von Henneberg, the last Komtur of the German Order at Prozelten before the 1484 exchange with Mainz. The castle itself was originally called Burg Prozelten. In 1493, Mainz accounts already record repairs to dilapidated buildings.
