Access: Easy. Drive to the church & get out of the car!

Not much to add to what Jane said, except that although we read that these are the remains of a cromlech, in 'Megalithic Brittany' Burl says it they are the remnants of an allee couverte.
Giot in 'La Bretagne des Megalithes' reckons it's the base of a neolithic tumulus.
This seems strange to us, though I guess it's possible if these are strangely varied & spectacular kerbstones.
