Tell Rousse is one of the largest and most interesting prehistoric sites in Bulgaria. It was 10 m high and was completely excavated during four main archaeological campaigns carried out in the previous century. The site was located near the right bank of the Danube River close to another tell smaller in size, which was inhabited in the end of the Chalcolithic. Tell Rousse was occupied for a long period. Eighteen construction levels dated back to the Middle and Late Chalcolithic were defined. There are serious problems related to the stratigraphic sequence of the tell and for that reason the artifacts do not provide reliable information.
