Ichan-Kala Citadel preserves the image of the ancient eastern city of Khiva. The findings of archaeologists suggest that Old Khiva, which already existed in the 5th century, served as a stage on the Great Silk Road. The old city, located inside the walls of Itchan-Kala, occupies an area of about 30 hectares and is surrounded by a massive wall of 6-8 meters. Ditches were dug on the outer side of the walls, which were filled with water. Also in the fortress wall there are four gates, reinforced with shock towers and complemented by viewing galleries.
