Archaeological research conducted on the large stone pile in the centre of the lot where the chain store Plodine (more precisely, its fruit department) is located, started under the assumption that this is a prehistoric barrow. The barrows were actually graves characteristic for prehistoric period, from the beginning of the Bronze Age forward. They are stone or earth mounds raised above the deceased to mark the grave. A large stone mound rising above the low plant landscape of juniper and olives, at a height of almost 4 meters and a diameter of 16 meters.
After removing the stone mound, the structures of dry-wall rings, which concentrically narrowed towards the centre to the smallest central ring, were exposed.
The dry-wall ring near the barrow is a common feature, which originally had a building function, but later on it turned into a symbol emphasizing the centre of the barrow, that is the grave. On the site of St Peter, as many as four dry-wall rings were found within the barrow, which reach up to three levels of stones, creating a dry wall with a regular outer side of the mantle.
The three peripheral rings were made on the same level, while the fourth central ring is on a lower level. Within the central ring, along its north (inner) mantle, there is a dry-wall structure with a relatively regular layout.
This specific architectural feature and the impossibility to find a similar object raises a series of assumptions about the purpose and, accordingly, determining the date of this architectural structure. The lack of an opening, which would suggest a passage among the rings towards the centre, shows that this characteristic is not functional, but tends to have a cult purpose.
The finding of the dry wall structure in the central ring, although without a grave, emphasized the importance of the central area. Even though the structure contains all the elements, there were no traces of the deceased, which represents a significant problem regarding the identification of the entire barrow construction.
The only logical solution leads us towards the identification of the entire mound as a barrow – cenotaph, or a symbolic grave constructed only in memory of the deceased, without the body, which for some reason could not be buried. The findings within the layers, the pieces of antique tegulas and a bronze belt buckle, determine the time of origin of this massive structure, and they stand as terminus ante quem non to its datation. The solution to the problem of identification is even greater because, owing to the lack of research of prehistoric barrows on the island of Krk, there are insufficient analogies to support this finding.
