The article refers to a new project started by the Università degli Studi di Napoli, l'Orientale in collaboration with the Institute of Archaeology of the Uzbek Academy of Sciences of Samarkand. The joint project is aiming at individuating a possible Achaemenid archaeological horizon in the area, which generally is very far to have been clearly detected by scholars. This short campaign had as main aims the cleaning of a long section (divided in two parts, section no 1 and section no 2), along a modern cut in the supposed external encircling wall around Koj Tepa. The pottery collected (among which a nice almost completely big jar of probably Achaemenid time, kumis in Russian) and the different layers individuated give evidence of a secondary moment of the re-utilization of the structural remains, clearly recognizable on the sections.
