Ringwall Koblenzer Dommelberg

Ringwall Dommelberg is a Celtic fortification in the forest near Koblenz with multiple oval wall sections surrounding a large area. Deep trenches run alongside the walls and together form a dense defensive system.

The fortification was built in two phases during the Iron Age, first in the 11th century BCE and then in the 6th century BCE. Archaeological work in the 1930s revealed how these phases fit into the site's development.

The fortification reveals how Celtic communities organized their settlement and controlled access to it. The southern gate was wide enough for people and goods to move through, showing this was an active place for trade and movement.

Forest trails with information signs guide visitors through the different wall sections. The site is best explored on foot, especially in warmer months when vegetation is less dense.

The walls contain remains of wooden reinforcements that show the Celtic builders used advanced techniques. These wooden structures were carefully integrated into the earthen walls to help keep them stable.
