The Mogao Grottoes complex in China consists of hundreds of caves carved into a cliff face along the Daquan River and lavishly decorated with wall paintings and sculptural works. Also known as the Thousand-Buddha Caves, the place contains approximately 45,000 square metres of murals and over 2,000 painted sculptures, making it the world's largest collection of Buddhist art. Inscribed as a UNESCO World Heritage Site in 1987, the grottoes are strategically located along the Silk Route, at a crossroads of trade, religious, cultural, and intellectual influences. According to UNESCO, the grottoes were first constructed in 366 AD.
