This Trajanic building (opus mixtum) consists of three shops along Via della Foce, behind which are a few small rooms. In the east part is an external staircase, of which only the threshold is preserved. In the central shop and in the room to the south of the staircase is a basin. The former has now disappeared completely. The latter basin suggests that the rooms behind the shops were not an apartment, but used for light industrial activity.
Plan of the building.
