In II-IV centuries AD the road through Bedel pass and southern Issyk Kul was already in regular use.
It became very active in the early Middle Ages when due to the civil strife in Fergana, caravans began to prefer this way to Fergana branch.
The structure is surrounded by a ditch, from 11 to 14 m in width.
Excavations revealed remains of inhabited and manufacture constructions inside the settlement, as well as outside.
This part of the road is well marked by different sites, especially for Muslim time when it was described in guidebooks as a transit corridor with two branches: i) through Osh - Medva (Mady) to the south in Alai valley and further through Terek-Davan to Kashgar; ii) from Osh to Uzgen, further through mountain passes, to the valleys of inner Tien-Shan and then split near At-Bashi, in two branches, first went through Tash-Rabat and Torugart passes to Kashgar, and the second - to the southern coast of Issyk Kul, through Bedel pass to Aksuu.
Considerable part of this road passed within modern administrative borders of southern Kyrgyzstan occupying foothill areas of east, southeast, southwest and northwest of Fergana.
The direction looked as follows: from Kashgar through Terek-Davan pass, to Alay valley, along Gulcha river and its inflows, went to Tar, then to Kara-Darya river, and to Uzgen city (where the most eastern city of Davan - Ju-chen is usually localised), then turned to the Osh oasis, and then went to the West (to capital Ershi) and to the North Kanguy.
One more type of monuments of this region is quarters of medieval nomadic rulers: sites of Koshoj-Korgon and Shirdakbek settlements.
Walls are made of paksa and mud blocks (remained height from 4 to 8 m).
Square adobe construction is located separately in 0, 5 km to the south.
