It was built by Artav, ruler of Khwarezm, and its history spans from the 1st to the 5th century CE. The site was explored in 1938, revealing wall paintings, coins, and archives. Toprak-Kala was influenced by the Kushan Empire, as evidenced by the discovery of their coins and sculptures. Nearby, the Kyzyl-Kala fortress provides further insight into the region's history.
