The sixth excavation campaign at Cittareale partially concentrated on an area not previously investigated, the zone in front of the church of San Silvestro, between the hamlets of Bricca and Collicelle.

On the basis of the results of the geophysical survey excavations were undertaken at circa 60m west of the church, covering an area of almost 285 m2. The remains of a wall on an approximately east-west alignment emerged. It was preserved for a maximum length of circa 15 m and to an average height of circa 0.50 m. This constituted the containing wall of a terrace created by slightly cutting into the slight slope of the hill, positioning the low wall directly on the clay, levelling the area south of it and covering it with a thin layer of soil and charcoal (as insulation against humidity from the nearby water-table). The terrace was finished with a compact layer of clay and crushed brick/tile on average 0.20 m thick.

The purpose of this structure remains unknown. It could perhaps relate to a second series of activities involving the area both before and after the creation of the platea. These activities were attested by the remains of four small and rudimentary kilns, two of which obliterated by the platea itself, whilst the other two were partially obliterated by the terrace wall.

The finds date these activities to the 6th-9th century A.D. Therefore, they were contemporary with the original phase of the church (an inscription recalls its re-consacration in 923 A.D., at the end of the Saracen incursions) and the deposition of the 52 tombs in the nearby locality of Pallottini (investigated in 2005-2006).
