The cult place dedicated to the eastern god Mithras was installed in the second half of the 3^rd century AD inside an earlier complex with shops.

One of the back rooms of a shop was transformed into a cult space where the podia (side benches) and a small altar were made from reused building materials.

The mithraeum retained the painted decorations of the preceding phase (2^nd century AD), probably belonging to a lararium (shrine of the household gods), depicting two snakes, a male identified by a crest and a female, on either side of a Genius with a veiled head and a cornucopia in his hand to symbolize abundance.

Since they were connected to the earth, snakes also played an important role in Mithraic religion.
