In this episode - The Art Gallery in the Desert, the Silk Road crew go to the Gobi Desert and look around the Mogao Caves at Dunhuang. The Mogao Caves consist of over 500 caves, more than 30 miles in length. There are thousands of murals and statues in the caves from 366 AD, encompassing the art styles of Greece, India and the many dynasties of China. These caves hand-tunnelled into the Mingsha Mountains are a tour-deforce of religious art. They exemplify man's striving to create a legacy of his accomplishments and beliefs.
