China’s 5,500-mile-long Great Wall is a timeless and iconic site. Once the world’s largest military structure, it is now a UNESCO World Heritage Site and an incredible tourist attraction. However, its beauty and history are sometimes marred by visitors “marking” the wall with graffiti. To combat this, officials are designating specific “graffiti zones” where tourists can leave their messages instead of leaving them on ancient stone or bricks. The first graffiti zone, made up of plastic screens affixed to the historic walls, is located in Mutianyu, a popular section of the wall about an hour northeast of Beijing. The wall will continue to be monitored by Chinese officials to combat graffiti on other sections of the Great Wall, but it is hoped that the “graffiti zones” will be enjoyable for tourists and help to preserve other sections of the Wall.
