Since 2007, our excavations concentrate on the West side of the forum. Three rooms, organised according to the regular plan of the colony (module of 5,5 × 11 m) are backed up against a large sewer at the foot of a terrace wall. On the terrace is a street (the Via Nova), partially excavated in 2007. In front of these rooms runs a portico which separates them from the Via Valeria and the forum proper.

The Northernmost room was excavated in 1960 by J.Ch. Balty. The central room, which occupies two modules, is covered with a white mosaic and is flanked on both sides by three Corinthian columns. It may have been a banquet hall for the magistrates of the city or the members of a collegium. The third room is the most complex and has been the object of investigation during the last three campaigns. Its floor and lower walls are covered with marble. On the western side, it ends with an apse and must therefore have been a small sanctuary (sacellum). Beyond the apse is a well which was excavated in 2010.

In 2011, our efforts concentrated on the portico in front of the third room. A white fresco painted with red letters had fallen onto the floor. Its surface had then been roughened with a pick to apply a second fresco. This new surface, more fragile, still presents traces of colour. The multiple layers as well as the fragmentary and chaotic structure of the fallen fresco made it particularly delicate to excavate. All the fragments were removed and the cleaning of the biggest one revealed that the text painted on the wall is a religious and legal calendar of the city (fasti). Below the fresco, the portico was covered with a white mosaic with a black geometric decoration and limited on either side by a stone border creating a “carpet” in front of this room.

During the 2011 campaign, a team led by O. Vrielinck mapped an important part of the sewer system that runs beneath the city. They also drew sections and detailed maps of specific areas of the sewers.
