Heidenmauer

Bad Dürkheim, Germany, Germany

---

Heidenmauer near Bad Dürkheim in Germany's Rhinland-Palatinate is a 2.5-kilometer-long Celtic ringwall built around 500 BC in the Murus Gallicus style, enclosing a 26-hectare hilltop settlement on the Kästenberg at 300 meters elevation, marking one of the Palatinate's earliest known urban centers from the late Hallstatt period. Constructed by Celts with timber frameworks that later rotted away, leaving visible stone foundations up to 6-8 meters high protected by a fore-lying ditch along half its length, the site served as a trade and craft hub for just 30-40 years before deliberate dismantling around 450 BC for unclear reasons. Ongoing excavations since 2004 as part of the DFG's "Early Celtic Princely Seats" program reveal pottery and artifacts, preserving it as a protected cultural monument accessible via forest trails amid the region's scenic vineyards.
