Not sure this is a bone fide menhir - can't find any trace of it in books on the area. No idea what it's called if it is genuine, so I've given it a name myself.

Looking for Menhirs de Roch Toul and Menhirs de Trimen we came across this stone. It's quite nice & very easy to find, but didn't look quite right if you know what I mean! (Though it looks more convincing in the photo....)
