This tiny shrine is situated at the west end of the row of shops III,II,10. It consists of a single, almost square room (c. 3.00 x 3.00). The masonry is described by Marion Blake as opus latericium and "opus incertissimum", but covered by plaster. Blake places the masonry in the second half of the second century AD.

The entrance is adorned by brick pilasters, supporting a plain frieze and tympanum. The room has a barrel vault. A brick podium was set against the back and lateral walls. In 1938 a fragment of a marble statue was found inside, possibly belonging to the cult of Dionysus: the lower part of a naked, young man, supported by the stump of a tree, from which a Pan-pipe is hanging down. Later the shrine was enlarged: a few walls created one room in front and two rooms to the left of the shrine.
