Located in the desert city of Dunhuang in Northwest China and along the famous Silk Road, the Mogao Grottoes (sometimes also called the Mogao Caves) are a UNESCO World Heritage site. The 492 caves house more than 2,000 sculptures and almost 485,000 square feet of murals. These ancient works of Buddhist art date back to 1,600 years ago. Since 2008, a series of preservation efforts have taken place to protect and develop the site. This month, a new visitor center opened, along with redesigned visitor pathways through the caves, increased security and sandstorm protection. In addition, a 3D exhibit opened that brings some of the world-renowned murals that were previously too delicate for public viewing to the public’s view through thousands of high-definition images merged into 3-D film footage and projected on-site in a dome theater. Visitors to the Mogao Grottoes are also now able to reserve tickets online in order to visit.
