The remains of the fortified northern walls of a citadel (?VI c BC – III c AD) are located just opposite the Tekesh mausoleum. The popular name of the citadel is Kyrk Molla (forty mullahs).
The citadel is perhaps the oldest part of Kunya Urgench. The earliest ceramics discovered here date back to V c. BC. The mount covering the rest of the citadel, has become a cemetery, where local pilgrims perform an unusual prayer ritual.
