Situated at an important juncture within the network of silk routes from China through central Asia, the oasis city of Dunhuang was an ancient site of Buddhist religious activity. Southeast of the city, the Mogao Caves, also known as the Caves of the Thousand Buddhas, are an astonishing group of hundreds of caves―carved in the cliffs between the fourth and fourteenth centuries―containing sculptures and paintings. Further east sit the Yulin Caves, another critical and richly decorated site. Featuring some of the finest examples of Buddhist imagery to be found anywhere in the world, these caves have enticed explorers, archaeologists, artists, scholars, and photographers since the early twentieth century.
