During Middle Age feuds between Western and Eastern Mongolians (Dzungaria and Khalkh Mongolia) after the collapse of the Mongol Empire. The armies of Dzungarian leader Galdan Boshigt noticed the golden roofs of the temples in Khogno Khan Mountain and massacred the partisan-monks of the rival Zanabazar in 1640, killing them by tying their necks with a rope (the Mongolian verb for the action is khognokh) as if they were goats and sheep. This is the meaning of name of the mountain. After democratic revolution in 1990 the monastery was restored by the granddaughter of the monks who was living at the monastery.
