The 2009 campaign continued research in the area adjacent to Temple C, uncovering in trench 5 (room A) and room D, inside the porticus, the levels relating to the construction of the temple building and of the forum’s back wall. In depth excavation in trench 5 brought to light layers datable to the 2nd century B.C. in which residual material from pits and holes was preserved suggesting occupation of the area dating back to the 4th century B.C. Moreover, in room A occupation levels and collapse relating to the Julio-Claudian structures were documented. One of the most notable finds was a goblet signed Marcus Perennius Tigranus.

During this campaign a last trench was dug in the forum itself, close to a number of walls of uncertain date. The excavation again confirmed the sequence of beaten surfaces documented in 2007-2008 and uncovered two cement structures whose function , for the moment, is uncertain.

Lastly, a new sector was opened in the area east of the porticus which closed the long side of the forum. On the basis of the results from the geo-magnetic survey undertaken in 2008, the existence of a long wall in opus incertum was confirmed. This ran parallel to that of the porticus at a distance of 15 m and probably delimited an open area, perhaps with a loose surface, and therefore a road. East of the wall other walls emerged which require further investigation. Traces of an earlier construction phase were seen in the lower levels: at least two pilasters were resting directly on the remains of a column made of brick wedges which was on the same level as another wall whose courses were in opus mixtum.
