The excavation, carried out in collaboration with the department of Archaeology of the University of Calabria (Prof G. Roma) and the section "Kyniskos" of the Gruppo Archeologico del Pollino (G.A.I.), concerned the stratigraphy beneath the presbytery of the Church of the Carmine, a small building in the historic center of San Sosti. The site, on the ridge of a large hill overlooking the ravine caused by the torrente Rosa, was occupied from the thirteenth century b.C. Buildings of the sixteenth and seventeenth century revealed by the excavation include rooms that can be interpreted as a kitchen and dining hall (a small oven, a cooking surface, many casseroles, large serving dishes and cooking pots, as well as bones from both wild and domesticated animals). Coins of the thirteenth-fourteenth century (a Castello Tornese of the Latin East)represent a significant find in the earlier stratigraphy, with clear connections to the finds at the nearby Castello della Rocca. The underlying strata include early medieval , late antique and imperial deposits, which contained many fine wares (Italian and Eastern Sigillata, African Red Slip),some millefiore glass of the first century B.C. and republican and imperial coins. The remains of a roman building are preserved on the south side of the Presbytery. There is no apparent trace of the first three centuries B.C., but beneath the imperial levels are found Greek material with attic imports (6th-4th centuries B.C.) The substantial remains of a building, under the modern sacristy, seem to belong to a sanctuary. In the foundations were found two votive deposits containing miniaturistic pottery (hydriskai, olpai, krateriskoi) and fragments of terracotta statuettes of women, both standing and seated on thrones. The importance of the site is documented by the traces of Recent and Final Bronze age 3 - Early Iron age IA, with the presence of painted micenean pottery of Late Elladic IIIC (early mid) and of painted enotrian ware of the Proto/Geometric and Early Geometric periods, datable respectively to the 13th-12th and the end 11th-early 10th centuries B.C.
