Lot (46)
Departement
Quercy Perigord megalithes

A great site predominantly about the Dolmens of the Lot department and some of Tarn & Garonne department.
There is an article from the french Archéologia about the Lot dolmens with an english translation at the bottom. Plus several pages of pictures the author has visited and also cupules (cups) and standing stones in the region.
