Koshoy Korgon
Koshoy Korgon is a fortified site on the At-Bashy plain in the inner Tian Shan. Its massive earthen walls enclosed a settlement identified with medieval Atbash, a town on routes between the Naryn country and Kashgar. The roughly rectangular fortress was protected by towers, and other small strongholds watched approaches through the valley. Archaeologists have traced occupation at the site through the medieval centuries.
