Precise length of Great Wall: 21,196.18 km
Precisely 1, how long is the Great Wall? This has been a long-unanswered question, as many dynasties in Chinese history built, modified or extended the Great Wall. But now, the State Administration of Cultural Heritage has announced a definite number after a seven-year investigation 2.
Twenty-one thousand one hundred and ninety-six point one eight Kilometers (21,196.18 km), That is the precise length of the Great Wall, which was included as a World Heritage Site in 1987.
Twenty-one thousand one hundred and ninety-six point one eight
Kilometers (21,196.18 km), That is the precise length of the Great
Wall, which was included as a World Heritage Site in 1987.
Built over two thousand years ago, the Great Wall is one of the largest construction projects ever completed. It's a series of fortifications made of stone, brick, wood and other materials built across the historical northern borders to ward 3 off invaders 4.
Although it is also called "wan 5 Li Chang Cheng", which means ten-thousand li long wall in Chinese, this is only a description for a very, very long wall.
To get the precise length of the man-made masterpiece, the State Administration of Cultural Heritage began surveying the wall in 2006. More than 2,000 technicians worked on the comprehensive survey using state-of-the-art technology, in 15 provinces, municipalities and autonomous 6 regions. The project proved to be very difficult as the Great Wall zigzags 7 and winds up and down mountain edges and valleys.
新闻资讯：在第七个“文化遗产日”来临之际，国家文物局5日在北京居庸关长城发布了长城资源调查和认定成果——中国历代长城分布于15个省区市，总长度为21196．18千米，包含遗产43721处。跨越15个省区市；长达21196.18千米；相关长城遗产43721处——这样一组数据意味着，目前全国仅仅7万名的文物工作者，都来保护一处处长城遗产，也依然捉襟见肘。古人有能力修筑如此规模的建筑，是奇迹；今人若能保护好古人创造的奇迹，也应算是创造了新奇迹。
