The Mithraeum of the Snakes measures 11.97 x 5.25. The main entrance is in the north wall, slightly off-centre, 1.70 wide. The wall on either side was created for the mithraeum. An opening in the south wall was blocked. The podia are made of rubble masonry. The western podium was reached along a brick tread. In the centre of the vertical part of the podium are niches. Set against the back wall is a structure consisting of two treads, between two walls. The upper part of the structure has not been preserved. In front is a small masonry altar.
