From various, often unreliable and scarce data, we may yet safely accept, that it really is the back-part of a Mithraeum. The rockface, in which the relief has been chiseled out forms the back-wall of the sanctuary, which lies against the mountain. Above the relief two grooves are hewn out, creating the impression, that the roof had been fitted into them. Of the sanctuary itself nothing was found back. At the foot of the rock, there are two fountains, the water of which pours out into two basins.
