Guldursun Kala is one of the largest and best-preserved fortresses of Ancient Khorezm. Built between the 12th and 13th centuries, it served as a stronghold against nomadic invasions and played a key role in regional defense. Its sheer size and strategic location demonstrate the importance of Khorezm’s fortified network during the medieval period.

According to chronicles, Guldursun Kala was completed during the reign of Khorezm Shahs as part of a vast defense line. Archaeologists believe that the fortress was active during the time of Muhammad II of Khorezm (early 13th century), just before the Mongol invasions. The site reflects both military architecture and urban planning of the Khorezm empire at its height.
Located about 30 km northeast of Khiva, Guldursun Kala is included in tours of the “Golden Ring of Khorezm Fortresses.” Due to its size, it is especially impressive to explore on foot, with wide views across the desert plains. The best times to visit are spring and autumn, when temperatures are comfortable for walking through the ruins.
