In 2007 a group of archaeologists found a partially collapsed cave containing painting depictions of scenes from Buddha's life in Mustang, the former Kingdom of Lo in northern Nepal.
Located at the height of 155 ft from the ground, these man-made caves are believed to be at least 3,000 to 2,000 years old.
Scientists divide cave use in Upper Mustang into three periods. As early as 1000 BC, the caves were used as burial chambers. During the 10th Century, the caves are believed to be used as living quarters. By the 1400s, the caves functioned as meditation chambers, military lookouts or storage units as people moved into villages.
