After a geophysical survey in 2015, research on the urban system of ancient Kaulonia continued with a first campaign of excavation. The aim was to collect new data regarding the urban organization of the northern part of the settlement during the Archaic to Classical and Hellenistic phases respectively. Approximately 80 m to the south-east of the ruined church of San Marco and about 10 m to the north of the building of Classical date excavated by Henri Tréziny in 1988, a trench was opened. At this position, the results of the geophysical survey indicated an east-west oriented street (stenopos) running perpendicularly to the presumed main plateia further west. Due to the proximity of the dune, the archaeological strata were covered here by a layer of sand with a thickness of nearly 2 m. The possibility exists that the stratigraphy has been partly obliterated because of the enormous pressure exercised by the ex¬tensive sand cover. In the limited excavated area, a substantial fill consisting of hard earth mixed with tile and pottery fragments was encountered. No architectural remains of the Hellenistic period could be detected. A Roman Republican silver coin (quadrigatus) and two Brettian bronze coins provide an indication as to the abandonment of the area around 200 BCE. In the southwestern edge of the trench, a wall pertinent to an earlier phase, but possibly reused in the Hellenistic period, was unearthed. The layers adjacent to this structure contained considerable quantities of tile and pottery fragments, includ¬ing a number of burned sherds, as well as some charcoal and several animal bones. No evidence concerning the presumed street has so far been found. Other small finds included five bronze nails, a small terracotta figurine depicting a pig and three loom weights. A small decorated terracotta altar dated to the first quarter of the 5th century BCE was found in what appears to be an Early Hellenistic context. Likewise residual are several much worn fragments of dressed terracotta figurines from the same deposit.
