In the summer of 2010 the first excavation campaign took place in the locality of Colle Rotondo (Anzio). This was preceded in 2009 by a survey in preparation for the excavation, which aimed to collect new information about the area and add to the published data (occupation from the Mid Bronze Age onwards, connections with the Recent Bronze Age necropolis of Cavallo Morto, diffused settlement in the Archaic period and votive deposit datable to between the Orientalising period and Republican period).

The excavations concentrated on three areas. In Area 1, by the remains of the settlement’s largest embankment on the eastern edge of the plateau, a section of the embankment was cleaned and two trenches opened. A large beaten surface with post holes was identified, but so far cannot be dated. To this aim radiocarbon dating will be undertaken on carbonised wood samples.

Area 2: a trench was dug in the central sector of the settlement. It revealed a disturbed stratigraphy. The remains of a number of pits dug into the bedrock were identified. These contained impasto pottery, minute fragments of bucchero and tiles of light-coloured impasto.
Area 3: a trench was opened on the western edge of the plateau, revealing a compact stratigraphy with material relating to the structure’s collapse in the mid Republican period.
