The 2012 campaign was concentrated in the area of the Rocca. The excavations, survey and topographical documentation involved three zones:
a) Podium/palace area;
b) Town walls (north and east side);
c) East terrace (medieval quarter).

a) In the area of the probable podium of the temple/palace of the counts of Tuscolo, the surface cleaning begun in 2009 continued and was extended. The existence of a first construction phase (A) of opus quadratum made of large tufa blocks, already interpreted as a probable temple podium, was confirmed. This was exposed for an overall length of 17 m and a width of 2.60 m. The podium was abutted by a series of later structures: the earliest related to a restoration of the podium (phase B) in opus reticulatum and a large wall with reused tufa blocks (phase C) probably dating to the late antique period, 11 m long and about 1 m wide. The podium’s south side was abutted by five parallel walls with a distance of 4.30 m between each. They were built in opus caementicium with abundant mortar.
In the medieval period the long opus quadratum wall was reused as the northern limit of a vast quadrangular room about 11 × 13.50 m, delimited by walls built in the same technique as those documented in the adjacent church excavated in 2008.
In the area south of the podium, various walls were documented, some of which of late antique/early medieval date. A wall of reused tufa blocks, almost 16 m long, found 10 m north of the podium, dates to the same period.

b) Large stretches of the town wall (north and east sides) were excavated. Along the north side, a stretch of almost 80 m (0.83-0.90 m wide; 0.35-1.70 m high) was documented. This was a wall with a double facing of reused opus quadratum blocks, flint and tufa chips and brick/tile fragments. Despite the uniform building technique, it is suggested that only the first part of the wall is ancient (51.60 m), as far as the limit marked by a Roman cistern, which was incorporated into the wall as a defensive element.

c) A new excavation area was opened on the Rocca’s east terrace. The first evidence documented the existence of a medieval quarter with a series of earth-built domus, on an east-west alignment and a surface area of about 50 m2. Soil samples were taken from in and around the houses for paleo-botanical analyses.
A topographical survey was made of the three excavation areas including photogrammetrical recording. The resulting digital images were geo-referenced and integrated into the overall plan of the site.
