William Lindesay

In 2017, he set out to capture the Great Wall in a new way using drone photography, an idea he got from his two sons, for his upcoming book, The Great Wall: High Above and Down Below. To achieve that, he and his family covered a distance of over 9,320 miles from China to Mongolia, travelling by foot and car.

In 2015, during an interview with The New York Times, Lindesay criticized museum curators at the Vatican Museums for refusing to grant him access to important maps and objects of research for his book, The Great Wall in 50 Objects, despite him raising $25,000 USD of the required funds. He said, "Museums are the best classrooms for knowledge and education, but some curators are like prison wardens, holding the keys, keeping the antiquities imprisoned, not allowing visitors, trying to keep people out."

In 2012, with the help of a Mongolian geographer and the assistance of the Mongolian Armed Forces, Lindesay became the first person to discover an unmapped section of the Great Wall hidden in the Gobi Desert bordering Mongolia and China, an area he had explored extensively since 1997. Carbon dating of his discovery estimated the rammed-earth structure he found to date back to the 11th century, meaning it was likely to have been built by the Western Xia Dynasty (1038–1227).

In 2008, he was named a "Top Ten National Defender of Cultural Heritage" by the Chinese government, and in 2016, he was awarded the Special Award of the Royal Society for Asian Affairs in recognition of exceptionally outstanding and unusual achievement in Asia.

In 2007, he curated The Great Wall Revisited exhibition at the Capital Museum in Beijing.

Credited with awakening China's national consciousness to protect the Great Wall and its environment, Lindesay was the first person to discover an unmapped section of the Great Wall in the Gobi Desert, and has served as an official ambassador for Great Wall conservation since 1998 when he received the Friendship Award from the People's Republic of China.

Lindesay's contributions to the conservation of the Great Wall and Sino-UK relations have earned him international recognition. In 1998, he was awarded the Friendship Award – the highest award for foreign experts who have made outstanding contributions to the country's economic and social progress – by the government of the People's Republic of China for his lifelong work in conserving the Great Wall. He received the medal from former Premier Zhu Rongji. In 2006, Lindesay was included in the 2006 New Years Honours Diplomatic Service and Overseas List, and was made an Officer of the British Empire by Queen Elizabeth II for services to UK-China understanding and to international conservation of the Great Wall.

Lindesay founded WildWall in 1987, a company that provides clients with privately guided tours and retreats at the Great Wall. He is a current honorary senior research fellow at University of Liverpool.

William Lindesay OBE (born 8 May 1956) is an English author, runner, and conservationist. He is best known for his work in protecting and conserving the Great Wall of China. He first went to China to run on the Great Wall in 1986, making the first documented traverse of the ruins on foot the following year, in 1987, in which he covered 2,470 km. He is a current honorary senior research fellow at University of Liverpool, and received the Royal Society for Asian Affairs’ Special Award in 2016.

Lindesay was born in 1956 at Wallasey, Merseyside, England. He first attended school at St. Aidan's Primary School, and graduated from the University of Liverpool with a Bachelor of Arts in Geography and Geology. After his graduation in 1979, he took his first job as an oil field worker in the Gulf of Suez. In his early exploration of the Great Wall of China, he decided to run the wall in its entirety, and managed to cover 2,470 km. During this time, he was stopped by police nine times for trespassing, arrested twice, and deported once.
