Local antiquaries pronounce this to be a fortified cave, unique of its kind, devised to protect the road to Lussac, at the strategical point where it could best be defended. I have myself no manner of doubt that it was a so-called demi-dolmen, a tribal ossuary of neolithic man. Not only is it quite in character with his megalithic remains scattered over the country, but treasure-seekers who in digging displaced and brought down one of the side slabs found two diorite axes, one of which I was fortunate enough to secure. Persons in Gaulish or post-Roman times would not have dreamed of going to the enormous labour and attempting the difficult task of forming the sides with stone slabs, but would have closed the recess with a wall. The cave goes by the name of La Grotte de Jioux (of Jove) which in itselt hints its remote antiquity.

But, although I do not believe that this cave was constructed as a military vidette and guard-house, I have no doubt whatever that it may have been so used, and it is very probable that at this point took place the first brush of Clovis and his Franks with the enemy, for the valley bears the name of Le Vallon des Goths.
