Several architectonic elements related to habitation and storage structures were revealed during the archaeological season of 2009 undertaken in the Neolithic settlement of Kallamas.
In the anthropic destruction level of sondages A5, A6, B3 and C1, the excavations uncovered a number of timber postholes and fragments of mud with thatches or straw, which are perhaps remains of the walls of Neolithic structures. However, the only visible structure unearthed during this season consists of a mass of baked clay fragments, whose shape suggest for a container, perhaps a silo used for storing grain (locus 805). The best-preserved part of the structures is the upper part, whose wall thickness varies from 2 cm at the top, to 5 cm at the bottom. The structure is made of sandy-clay material, rich with plant remains, such as fragments of straw and rids (which are still visible). The integral materials show for the different construction techniques used in the structure: the inner side has been uniformly worked and baked; the filling or the core part less so; while the outer was not worked at all. Therefore, it was not easy to distinguish the outer part of the structure from the natural surrounding sediments; also for the same reason it was impossible to clearly separate the vegetal components used in the construction from those of the environments. All the evidence suggest that the structure was probably a storage space, constructed within a ground hole, whose bottom and sides were covered in mud plaster made of sandy-clay soils and then burnt from the inside, in order to consolidate the structure. This is a well known practice, which has also been widely proven from the experiments undertaken in the Neolithic Aegean world, as for example the case of Dikili Tash.
