The Kizil Grottoes in China's Xinjiang built in the third century are among China's earliest sites of large-scale Buddhist grottoes along the Silk Road. Relic protectors are making continued efforts to preserve the ancient murals.

Kizil Grottoes are part of the Silk Road's Routes Network of Chang'an-Tianshan Corridor, a UNESCO World Heritage List.

With 10,000 square meters of frescoes and colorful sculptures, the Kizil Grottoes reveal the history of Buddhism spreading eastward via the western region.
