The part of the house transformed into a Mithraeum has two rows of three pillars, which divide the sanctuary into three sections. In the middle section runs a central-aisle between two small benches (H. 0.40 Br. 0.25), constructed against the pillars. In the right bench, before the middle pillar, is a small rectangular depression (L. 0.10) and in its base a niche (H. 0.35 Br. 0.42 D. 0.30) in which bones of fowls have been found.
