A few kilometers to the south of the ruins of the medieval Sultan Kala we find the post-medieval city, known today as Abdullakhan Kala, constructed in the period that Timurids ruled the area.

Despite being one of the strongest and best fortified cities in the area, Abdullakhan Kala never reached the importance of its predecessors, although the city walls are still impressive. Bairamali Khan Kala (XIX c.) was the last clay-walled urban site in Merw, and has been poorly preserved.
