In 1938, during the archaeological excavations in Khorezm, an ancient settlement of Kirk-kyz-kala dates back to I-VI centuries AD was discovered. According to scientists, this fortress was created for the defensive purposes of the north-eastern border of ancient Khorezm.

A lot of legends are associated with the name “Kirkiz-kyz-kala”. The translation of the name means “Fortress of Forty Devas”. According to one common legend, the fortress was the haven of Amazon warriors, who for many years guarded it against strangers. There is a folk poem “KyrkKyz” in the Karakalpak epic which describes their life. Another legend claims, they were forty exiles who were forced to live in a fortress. According to one of the myths, it is righteous who turned into stones to protect themselves from their pursuers. In the mythology of the peoples of Central Asia, it was believed that these were forty spirits helping people in difficult times.

For many centuries, Kyr-kyz-kala was an important point and trading link on the Great Silk Road.

During the study, archaeologists discovered Zoroastrian burials on the fortress territory, in ceramic jugs in the form of female heads called huma.

The fortress was divided into two parts with different layouts, which united the walls and the gate from the east side. The construction itself consists of raw brick with the addition of adobe, the arches were made of burnt bricks.
