The menhir is located in the marsh of Aubigny-au-Bac, on a footpath leading to Brunémont. It is a block of Landenian sandstone 2.90 m high (including 1.48 m above ground) by 2.15 m wide and 0.70 m thick. It is said to have been sunk to about 2.40 m. Shaped like a horse's head, it is associated with a prehistoric megalith despite the absence of evidence.

Menhir part of the local history to discover. Be careful, the place is very swampy and it is more easily accessible in dry weather 😉.

It is a magical place, sheltered in a small clearing, which is accessed by a footbridge. Don't make (too much) noise ...
