Also known as the Caves of a Thousand Buddha’s, this UNESCO World Heritage Site contains some of the finest examples of Buddhist art spanning a period of 1000 years. According to local legend, a Buddhist monk, had a vision of a thousand Buddha’s, which inspired the excavation of the caves he envisioned. The number of temples eventually grew to more than a thousand. As Buddhist monks valued austerity in life, they sought retreat in remote caves to further their quest for enlightenment. Among the thousands of items discovered in 1907, by a western explorer, was the world’s earliest printed book, in scroll form.
