The Astrakhan region can boast of an ancient settlement Sarai Batu - the former capital of the Golden Horde and a major ancient trading center
From about 1710 to 1765 there was a nitrate factory in these places. The part of the ancient settlement was surrounded by a stone wall. Bricks from the settlement were also used in its construction.
In 1770 such remaining buildings were mentioned: a mosque, mausoleums and underground crypts.
In 1333 Arabian travellers mentioned that the settlement was inhabited by Mongols, Kipchaks, Circassians, Russians and Byzantines.
