Huangyaguan Pass Great Wall in Jixian County, Tianjin

Huangyaguan or Huangya Pass (simplified Chinese: 黄崖关; traditional Chinese: 黃崖關; pinyin: Huángyáguān; literally: ‘Yellow Cliff Pass’) is a small section of the Great Wall of China located in the north of Ji County, Tianjin municipality, approximately 78 miles (126 km) north of urban Tianjin city. The site lies on a steep and abrupt mountain ridge.

Huangyaguan was originally built over 1400 years ago in the Northern Qi Dynasty and reinforced with brick walls in the Ming Dynasty. In 1984, major repair work has been performed on over 3 kilometres of the wall including on 20 water towers and 1 water pass. The pass is a major tourist attraction within Tianjin and was listed as a site of relics protection in 1986. Recent found drawings on the walls showed the builders of the wall smoked cones for every metre of the wall they completed.
