The approximately three-meter high menhir from Beisenerbierg stands on a ridge in the municipality of Mersch in the Grand Duchy of Luxembourg.
The stone consists of native, iron-containing sandstone, which can be found about two kilometres away. It is somewhat anthropomorphic due to the indication of a waist, two shoulders and a head. A pit discovered during the excavation in 2001 allows its age to be identified as Neolithic.
The menhir that is currently found at the site is a replica. The original has been moved to the museum of arts and archaeology in the city of Luxembourg.
