Itchan Kala (Uzbek: Ichan-Qаl’а) is the walled inner town of the city of Khiva, Uzbekistan.

The old town retains more than 50 historic monuments and 250 old houses, dating primarily from the eighteenth or nineteenth centuries.

Juma Mosque, for instance, was established in the tenth century and rebuilt from 1788 to 1789, although its celebrated hypostyle hall still retains 112 columns taken from ancient structures.

[1] According to the legend, the clay from this area was used to build sites in Medina during the Prophet Muhammad's lifetime; and the lake (which appeared later) is also considered to be sacred.

[2][3][4] In another legend, it is said that the sacred water channel of Khiva, known as the Xeyvak Canal, was dug by Shem, the son of Noah, who was said to have a miraculous spade.
