Outside the monastery walls are two stone turtles. Four of these sculptures once marked the boundaries of ancient Karakorum, acting as protectors of the city (turtles are considered symbols of eternity). The turtles originally had an inscribed stone stele mounted vertically on their back.
One is easy to find: just walk out of the northern gate of the monastery and follow the path northwest for about 300m. Often, an impromptu souvenir market is set up here, lining the path. You’ll need a guide to find the other remaining turtle, which is on the hill south of the monastery.
