Jiankou (Chinese: 箭扣; pinyin: Jiànkòu) is a section of the Great Wall of China. In English, 'Jiankou,' is translated to 'Arrow Nock' as the shape of the mountain resembles an arrow with the collapsed ridge opening up, reminiscent of an arrow nock.[1] The wall is 20 km long and located 73 kilometres (45 mi) north of Beijing in the Huairou District.[2] The Jiankou section of the Great Wall of China is located between the Mutianyu and the Moshikou sections of the Great Wall of China. It is built on a steep mountain ridge and a popular hike amongst visitors.[1]
As well as natural causes, human activities are increasingly raising concern for the preservation of this section of the wall, as "the lack of work on the wall made it picturesque, but dangerous".[2]
This tourist attraction was temporarily suspended during 2020 due to covid-19.[3]
