Zagzuugiĭn Balgas
Zagzuugiin Balgas is a walled ruin in the upper Selenge country of northern Mongolia. It belongs to the period of the Uyghur Khaganate, whose rulers established fortified settlements in several river valleys of the steppe. The site lies in the region of the Delger Mörön, which joins the Ider to form the Selenge. Its surviving walls recall an age when fortified centres stood alongside mobile life on the grasslands.
