The sanctuary has been constructed in two vaulted rooms of a large house and has the stereotyped division into central aisle (Br. 1.87) and two side-benches (H. 0.45 Br. 1.17), which slope down towards the walls. At a distance of about 4.00 from the main entrance there are deep niches (H. 0.20 Br. 0.25) in them covered with terracotta.
