The Kurgancha Complex (XII to the beginning of the XIII centuries A.D.) consists of a settlement, a tower, a pottery kiln and separate constructions. It is located under the chink of the Ustyurt Plateau, 105 kilometres northwest of the city of Muynak.
The ancient city is repeatedly mentioned in the historical literature of the XIX century. It has a rectangular form, with the city angles oriented to the cardinal points. The outline of the rooms can be traced along the eastern wall and the eastern part of the northern wall. Blue glass beads and shells with holes for stringing were found in one of the rooms.
The ancient city has the remains of a trading station situated far away in the north where Khorezmians traded with northern nomads. According to research, it was used again in the XIII–XIV centuries.
