The 2004 excavation aimed to clarify the function of the structure, constructed directly on a bank of compact loam used as a supporting base, on which the façade of S. Marco stands.

The complete emptying of the limekiln and the removal of the burials revealed that the squared blocks found along the west wall of the limekiln were part of a building of Roman date and were structurally linked to the other blocks found near the burials below the church wall.

The cemetery area next to the church was almost completely excavated and its use runs from the 12th-13th centuries to the 18th century. Skeletal remains were found in single burials (in earth graves without wooden coffins and on three different alignments), multiple burials (both in earth graves and masonry built tombs) and in two ossuaries. The multiple burials probably contained individuals from the same family, as can be inferred from the position of the bodies which underline the relationships between the individuals. The grave goods comprised metal objects relating to the deceased’s clothing (belt buckles, buttonholes, eyelets for laces, rings and earrings). Various finds not strictly linked to the burials were recovered, dating from the late Roman period up to the last century. Moreover, 7 coins belonging to a small hoard were found, 6 of which were silver and illegible and one well preserved gold solidus dating to between the second and third decade of 6 A.D. One face bears the icon of the emperor Justinian identifiable by the legend “DNIVSTINIANVS.PP”, the other side shows an image of winged Victory and Christian symbols and the legend“VICTORI.AVGGG.A.CONOB”.
