Graffiti is such a huge problem for the Great Wall of China that the authorities there apparently decided to give up a specific part of it for visitors to leave their mark on, so as to contain the damage and spare the rest of the iconic stone monument. There are also plans to erect an electronic touchscreen wall in future. Only time will tell if this works.
