SIRIS-Project, Preliminary results of the 2026 excavation campaign

 

 

Area Spring Sanctuary East (SSE)

 

 
 
In the area of the eastern spring sanctuary, excavation trench SSE04 was established during the 2026 campaign. This trench served to significantly expand on the previous year’s trench, SSE02, with the aim of more precisely documenting the archaeological situation within the surface-visible remains of the eastern temenos. The focus of the investigations was on the earlier wall uncovered in 2025, as well as the immediately adjacent votive deposits, which date to the 6th century B.C.

The aforementioned earlier wall was documented continuously along its entire length of approximately 7 meters. In the adjacent excavation area, several concentrations of iron and ceramic objects were uncovered. Similar to the “Humboldt hoard” recovered in 2025, these finds originated from a water-bearing clay layer; their restoration and presentation are currently underway at the museums in Policoro and Sybaris.

 

Among the metal finds, one hoard stands out, consisting of a large number of iron obeloi approximately 1 meter long—spear-like metal rods that served in Archaic Greece as a pre-monetary means of payment as well as ritual and sacrificial implements. A detailed analysis of these finds promises further insights into the ritual practices of the Archaic sanctuary.

 

In addition, numerous well-preserved ceramic vessels and fragments of votive terracotta were recovered. The excavation of the transitional area between the active sanctuary site and the sterile sandy slope has also provided new insights into the sanctuary’s topography.

 

Based on this year’s findings, it can be tentatively concluded that a sprawling ritual area existed to the east of the spring sanctuary in the sixth century B.C. In subsequent campaigns, these findings must be contextualized through further excavations in order to better classify the evidence.

Area Collina West (CW)

The primary focus of the excavations in the Collina West (CW2) area was on investigating the Archaic-period fortifications of the Greek settlement of Siris. The specific goal of the excavations was to more precisely map the course and structural composition of the early city wall, thereby gaining a better understanding of the settlement’s development during the Archaic period.
 
During the excavations, sections of an early wall structure made of unfired mud bricks were uncovered and documented. The findings thus provide important insights into the construction methods and organization of the early settlement, as well as into the development of its fortifications.
 

Particularly noteworthy is the composition of the mud bricks, which were made from different types of clay. The preserved unfired mud bricks provide important evidence of ancient construction techniques and allow us to examine not only the structural design of the fortification but also questions regarding the production and use of the building material. The detailed documentation of the wall structures and their respective construction phases also helps to reconstruct the original layout of the fortification and its integration into the topography of the settlement.

 

The exposed structures significantly expand our current understanding of the archaic fortification at Siris. Together with previously known findings, they allow for a more precise reconstruction of the settlement’s spatial extent and architectural development. Furthermore, they provide new insights into the function of the fortification within the settlement’s organization and the strategic importance of Siris in the context of Greek colonization of southern Italy.

 

Further investigations are intended to help more precisely classify the individual construction phases and the layout of the fortification and to understand its development in the context of the Archaic settlement history of Siris.
