There are more than 1,000 UNESCO World Heritage sites spread across the globe, encompassing locations as diverse as Ethiopia and Iceland. Competition among nations to have their historic ruins and pristine wildernesses appear on the list is fierce as an appearance brings with it prestige, tourist numbers, and protection.

At present, there are 1,073 properties on the list along with 193 nations that have signed the treaty.
