The largest-ever preservation project at Mogao Grottoes, a collection of ancient Buddhist cave artworks, has been completed recently. The grottoes are now reopening to the public.
Occupying the caves on a 1,700-meter-long cliff, the Mogao Grottoes has some finest Buddhist frescos and sculptures, which were made as early as 1,600 years ago. Since late 2008, a series of preservation efforts have taken place at the Mogao Grottoes, including cave consolidations, redesigned tourist footways, security and sandstorm-protective facilities.
