About
Underground Project 131 (Chinese: "131"地下工程; pinyin: "131" Dìxià gōngchéng) is a system of tunnels in Hubei province constructed in the late 1960s and the early 1970s to accommodate the Chinese People's Liberation Army command headquarters in case of a nuclear war. The facility was never fully completed or used, and is currently open to visitors as a tourist attraction.
Some of the signage at the site refers to the facility as Chengshuidong Tourist Area (澄水洞旅游区).
