Khushuu Tsaidam Monuments to Bilge Khaan and Kul-Tegin, dated 732 AD, were found 47 km to the northwest of Karakorum, part of the Orkhon Valley Cultural Landscape UNESCO world heritage site. This collection of historical heritage includes stone monuments with runic inscriptions, stone turtles, human statues and other relics. Both monuments were dedicated to Turkish khans who ruled Mongolia between the 6th and 8th centuries.
The 3.3 meter high and 1.3 meter wide stone monument known as the Orkhon Bichig (letter of Orkhon) is a letter with 68 lines. There used to be a whole monumental complex, but now only one monument which named Gerelt Khushuu is left.
