The complex, variously interpreted as an aristocratic domus (house) or as the headquarters of a corporation, represents the late transformation (4th century AD) of an earlier building of the 2nd century AD.
An exceptional wall decoration of marble inlays (opus sectile), with geometrical, plant and figurative motifs, was found in a state of collapse in the main room, overlooking the sea. The presence of the portrait of a bearded man with his right hand raised and a nimbus (halo) has suggested that it might have been a Christian building or the seat of a pagan philosophical sect.
