In June 2013, a new excavation campaign began in the archaeological area of ancient Pitinum Pisaurense.
The trenches were positioned based on the geophysical survey undertaken in 2012, which identified parts of the urban structure.

TRENCH 1
Situated at the south-west corner of the field south of the church and opened in order to check the geophysical results that indicated the presence of a large sub-rectangular building with numerous interior dividing walls.
Part of a large building was exposed, its north wall on a north-west/south-east alignment and c.95 cm wide, built of roughly-worked stone blocks bonded with yellow mortar. The wall, whose precise date remains to be defined but attributable to the early imperial period, was built on top of a large wall made up of large stone blocks bonded with earth. This was only partially exposed and probably related to the first phase of this building, perhaps dating to the late-Republican period.
Numerous holes and their fills constituted by brick/tile, stones and pottery were excavated, probably dumps. Within these layers, which coin finds dated to between the 3rd and 4th centuries A.D., there were numerous pottery fragments and metal objects in secondary deposition, including two small bronze statuettes datable to the 1st century A.D., one of a lare and the other a warrior with shield and sword.

TRENCH 7 and TRENCH 8
Trenches 7 and 8 were situated close to the church of San Cassiano and the excavation of the so-called decumanus. The aim was to expose the paved surface (already partially excavated) to the side of the church and check for the presence of walls and/or buildings in its proximity, hinted at by finds of numerous terracotta slabs and marble fragments during the laying of a water pipeline last century.
Trench 7. A substantial level of stone and brick/tile rubble was removed that perhaps related to the rebuilding of the church in the medieval period. In the eastern part of the trench, a part of a surface paved with sandstone slabs was uncovered, which may have been the continuation of the paving excavated alongside the church. Several phases relating to the use of the paved surface were identified, dating from the imperial until the late antique/early medieval period.
In correspondence with the south and west trench edges, four inhumation burials were identified, but not excavated, in the section. Early medieval in date, the burials were aligned east-west and placed inside coffins made of stones and covered by stone slabs.
