Celtic circular wall of Otzenhausen

Ringwall von Otzenhausen

The Celtic hill fort of Otzenhausen (Hunnenring) is a large Iron Age enclosure on the Dollberg hill in Germany, built by the Treveri. Today the site is known for two broad circular earth-and-stone ramparts; the rest of the fort is wooded. Its visible remains are the rubble-covered embankments that once formed a continuous defensive wall around the summit.

What Celtic circular wall of Otzenhausen looked like in its prime.

On the rounded triangular summit of a forested hill sit two broad, concentric curving ramparts formed from heaps of quartzite rubble and packed earth, their outer faces built up with layers of large stones. The main enclosure follows a long crescent silhouette with a lower, parallel outer bank on the southern side set about 40 metres forward. The western approach contains a wide entrance area; the interior is an open, level plateau with regular post-sockets in the ground.

Its story

The story of Celtic circular wall of Otzenhausen.

The hill fort of Otzenhausen, on the 695-metre Dollberg, is one of the biggest fortifications the Celts ever constructed, built by the Treveri tribe who lived in the region to its north. The first fortification went up in the 5th or 4th century BC, with the real heyday of construction in the 2nd and 1st centuries BC, before the fort was abandoned, for unknown reasons, in the middle La Tène period.

The triangular enclosure measures 460 metres west to east and 647 north to south, ringed by 2,500 metres of ramparts containing 240,000 cubic metres of stone, once faced with thousands of timber beams, a construction Julius Caesar describes for Gallic walls in his Commentaries on the Gallic War. It may have been more than a refuge: perhaps a settlement or the seat of a local leader. Two stone-covered earth ramparts remain visible today.
