Hillfort of Otzenhausen

The Celtic hill fort of Otzenhausen is one of the biggest fortifications the Celts ever constructed. It was built by Gauls of the Treveri tribe, who lived in the region north of the fort. The fort is located on top of the Dollberg, a hill near Otzenhausen in Germany, about 695 m above sea level. The only visible remains are two circular earth ramparts, covered with stones.HistoryIn times of war, the circular rampart was a strong fortification against enemies. Theories suggest this one might have been more than just a refuge. There might have been a permanent settlement, a village or the seat of a local leader.The first fortification was constructed in the 5th or 4th century BC, but the real heyday of construction dates to the 2nd and 1st century BC. For reasons yet unknown, the fort was abandoned shortly after this expansion.
