A superior residence stands on the southern slopes of the hill, spreading over its natural terraces: it was constructed at the height of the imperial period (2nd century AD) and embodies elements of Hellenistic architectural tradition.

  The building includes a courtyard with columns (peristyle), which was originally paved with blocks of marble and geometric mosaics on three sides. Water supply was guaranteed by a great cistern, hollowed out of the rock. A porticoed atrium (pastas) faced onto the peristyle and was linked with three intercommunicating rooms to the north, and with other rooms to the west. The rooms are mostly paved with polychrome and black-and-white mosaics, usually bearing geometric motifs; figured elements are fewer, and include dolphins and a drinking set (a cup between two jugs) for symposium. Frescoes survive on the walls, representing panels framed by plant motives and separated from the dado by horizontal bands. The house had rooms on the upper floor, with one or more stairs leading up to them on the west side.
