Beyond the theatre the areas situated below the complex were examined. Immediately south-east of the theatre’s porticus post scenam (area B), is a terrace sloping down to the present Porta dei Cappuccini which was occupied in antiquity by a grandiose suburban villa perhaps dating to the first half or the first quarter of the 1st century B.C. The villa was situated at the edge of the construction free area surrounding the theatre.

Excavations showed that the villa was supported by a tract of the 4th century B.C. town wall. The blocking of a number of rooms and the pottery recovered from the excavation confirmed that the villa was occupied until the mid Imperial period. A central room was identified, facing onto a peristyle paved in perfectly preserved opus spicatum. Two large fragments of Egyptian grey granite columns lay on the paving. The ambulatory walls were visually linked to the granite columns of the peristyle through the use of masonry-built half columns which echoed their positions on the inner wall. One of the excavated rooms had plastered walls with traces of frescoes, whilst the floor was in opus signinum ornamented with coloured marble tesserae. The second room presented a fresco with a yellow dado with a tuft of greenery and white panels with red borders.

A vast rectangular triclinium opened off of the back of the ambulatory, delimited by walls on which traces of painted decoration were still visible. The mosaic floor had a background of white tesserae, set diagonally, and a central panel of opus sectile bordered by a motif of crossed buds forming circular elements.

In the pars rustica the torcular comprised a room on two levels: in the upper part the lapis pedicinus was set into the opus signinum floor. The lower floor had two large trachite stone bases showing the remains of the cavities in which the coclea was fixed allowing the prelum to be lowered and thus press the grapes.
