City Wall of Khiva in the Xorazm Province of Uzbekistan

de bene esse: literally, of well-being, morally acceptable but subject to future validation or exception 

Khiva is split into two parts. The outer town, called Dichan Kala, was formerly protected by a wall with 11 gates. The inner town, or Itchan Kala, is encircled by brick walls, whose foundations are believed to have been laid in the 10th century. Present-day crenellated walls date back to the late 17th century and attain the height of 10 meters.
