The Public Relations Office of the Research Institute of Cultural Heritage and Tourism (RICHT) quoted head of the first season salvage speculations for evaluation of the present sites in the neighborhood of Chamshir Dam Mohammad Taqi Ataei as saying so far the most ancient evidence obtained from the basin of Chamshir Dam in Gachsaran belongs to the epipaleolithic era and then with a long break little settlement evidence of the late neolithic era has been obtained which dates back to six thousand years ago.
Taqi Ataei said during archeological surveys over 120 ancient sites have been identified and documented in that zone.
Although a few strongholds and castles show the significance of the site from the post-Achaemenid and Sassanid eras, the peak of attention for this area has been in the middle Islamic centuries which is indicative of high demographic density in that region, he said.
He pointed to identification of scores of settlements of that era on the edge of the river saying that some of the settlements occupied an area of over 5 hectares.
Most of these settlements enjoy consolidated architecture and the natural resources of the area have been used as construction materials and stone and mortar filling have been used in normal buildings and stone and plaster mortar in more important establishments, he added.
