The Duisburg Dolmen Stone is a large historical erratic boulder in Duisburg (a district of Tervuren). It is often associated with prehistoric rituals and may have been part of an ancient burial monument (dolmen), although this has not been proven with certainty. The stone is primarily considered a local archaeological and folklore monument, commemorating the very early settlement of the region.

Narrow path next to the Voer. It can get quite busy, with lots of walkers, joggers, and horseback riders.
