The menhir Hilgenstein is situated in the south of the village of Werkel, east of a development area in the street Am Hilgenstein.
The menhir is 1.5m high and 0.5m (base) respectively 0.3 m (top) wide. As there were no archaeological finds found nearby, it could not be dated beyound doubt. It is assumed that the current location is not identical to the original location.
