UNESCO’s list of World Heritage Sites reached 1,000 locations this week after Botswana’s Okavango Delta was added to the prestigious register. Nearly thirty other historical spots spanning the globe were also inscribed. The list, managed since 1978 by UNESCO’s World Heritage Committee, includes such famous landmarks as the Great Wall of China, Peru’s Machu Picchu, and Grand Canyon National Park.
UNESCO’s World Heritage list aims to protect cultural locations around the world that represent significant importance to humanity. The UNESCO website classifies the sites in multiple categories, most notably by whether they are natural or man-made as well as whether they are considered in danger. Sites are nominated by World Heritage Convention signatories and evaluated by two separated bodies. The World Heritage Committee decides during its annual meeting which sites to inscribe on the list.
