The 2007 campaign mainly concentrated on two sectors where work had begun in preceding seasons: the area of the postscaenium (extension of trenches 19 and 17, trench 21 and 22) and the area of the theatre’s lateral portico (trench 20), where the historical sources indicate the presence of a porticus ad scaenam.

As regards the area of the postascaenium, two rectangular spaces were identified. The first was directly linked to the back wall of the postscaenium, while the second showed no evidence of links to other structures. Trench 21 was opened in order to investigate whether these rectangular structures could have continued in a regular pattern. However, there was no evidence for this.
In the eastern sector, between the scenic building and the containing wall with exedras delimiting the Greek theatre, where an interesting nymphaeum with exedra was found in 2006, the water table rises at a higher level. For this, reason excavations continued in this zone as well as in the two main areas. The excavation of the nymphaeum ’s fountain structure was completed together with that of an interesting tunnel behind the niche.

The work on the lateral porticus aimed to localise the southern end of the upper portico (trench 20 Sur) and, with the opening of trench 20 North, the identification of the link between the portico with opus sectile floor and the upper portico.

The excavations in trench 20 S showed that the building continued to the south. Another large tunnel was found in this area, interpreted as a modern quarry for pozzolana, similar to others found in the surrounding area. The organisation of the terrain towards the east side of the structure was interpreted as the preparation for a viridarium.

In the second excavation area (Trench 20 north), the excavations identified the closing wall at the southern end of the upper portico. It was also seen that the lower portico paved in opus sectile continued as far as the containing wall.
