Two trenches running parallel to the line of a gas pipeline were opened at Serra del Cedro in order to intercept the continuation of the walls seen in 1986 during a rescue excavation when the gas pipes were laid. There were no traces of structures in the first trench (a), 10 × 1.5 m. The second (b), on the same alignment but 11 m downhill, revealed evidence of a tomb and the wall of a house, which document the two phases of this part of the site’s use. Tomb SDC 1-2015, datable to the second half of the 6th century B.C., is a grave measuring c. 1.90 × 0.90 m, cut into the conglomerate of rounded clasts (pudding-stone) that forms the subsurface of the hill. The skeleton was that of a young adult male, lying in foetal position, arms crossed, on his right side. The tomb group was made up of iron weapons (knife, javelin and lance heads) and nine vases, including an Ionian B2 cup. At four metres to the east of this burial, the natural conglomerate had been cut to form a level platform downhill for the construction of a house, datable to the 4th-early 3rd century B.C.

A geophysical survey was carried out at Serra del Cedro in 2014 and a field-walking survey was undertaken on the site’s easternmost hill. The aim was to create the most objective maps possible of the distribution of brick/tile, without extrapolations, geo-localising every fragment using GPS and inserting the data into a GIS. One of the principal results was the identification of a dense concentration on the southern part of the hill: 3357 tile fragments over a surface of c. 2,500 m2. The ceramic material can be dated to the 4th-3rd century B.C.
