An opening 6 m long and a little less than 1 m high leads to a 2 m drop, but the easier access is on the right, where a ramp (partially occupied by a roll of metal mesh left over from the road protection) takes us to a gallery parallel to the entrance opening. On the floor we see an accumulation of blocks resulting from the archaeological excavation. The gallery turns right at the end and narrows, and after 4 m it turns left again to end, after 5 m, in an accumulation of blocks.
