Thareli site excavation was conducted by the Japanese Archaeological Mission under Prof. S. Mizuno in 1963~1967. The site is situated in a narrow gorge, secluded from the township and crowds. The excavation revealed over 100 buildings in the mountain and thousands of stone and stucco sculptures, coins, pottery, iron implements. Despite the peculiarity of the monastery's location, it is one of the largest known Buddhist complexes in Central Asia.
