The Buddhist cloister of Ajina-Tepa is situated 12 km east of the city of Kurgan-Tiube; Tajikistan. According to archeologists; the cloister was built in the 7th - 8th centuries CE. Ajina-Tepa was a name given by the locals to the hill under which the ruins of the cloister lay hidden. The name translates from Tajik as 'Devil's Hill'; as it is believed that the place is the abode of evil spirits.

The excavations of the hill were started in 1959 by Soviet archaeologists. The cloister had 2-m thick walls; built out of massive blocks of adobe; and consisted of two rectangular courtyards; surrounded by stupas; corridors and cells. More than 600 works of art; found during the 15 years of excavation; indicate how rich the original decoration of the temple was.
