Koshoy-Korgon is a large mud-brick fortified settlement on the At-Bashy plain, roughly 12-15 km from At-Bashy near Kara-Suu village. Do not expect a reconstructed castle: the appeal is the scale of the earthwork itself, with a rectangular enclosure of about 245 by 250 m, surviving wall lines, towers and a ditch that still make the medieval footprint easy to read. The site is usually linked with the Turkic and Karakhanid periods. Accounts date the fortification broadly to the 7th-10th centuries and identify it with the medieval town of At-Bash, a point on the route between Kashgar and the Naryn region. Archaeological finds point to craft, trade and domestic life inside the walls, while local legend ties the name to Koshoy from the Manas epic. A small historical museum stands beside the ruins with excavation finds, household objects and reconstructions. For most travellers this is a compact cultural stop on the way to Tash-Rabat or through the At-Bashy valley: allow time to walk the open site, but confirm museum access and current fees locally before relying on them.

Do not climb the mud-brick walls or remove pottery and other fragments from the site. Phone signal and services outside At-Bashy are limited, so keep offline maps and leave time for the return drive.
