Baiheliang Underwater Museum

About

The Baiheliang Underwater Museum or White Crane Ridge Underwater Museum (simplified, traditional) is an underwater museum built around the White Crane Ridge of Fuling District, Chongqing. It is China's first underwater museum. The museum is located on the Yangtze River in the Three Gorges area, near the Three Gorges Dam; it opened on May 18, 2009. The construction of the museum began in 2002 and has cost around US$28 million. The main architect was Ge Xiurun of the Institute of Rock and Soil Mechanics and the Chinese Academy of Sciences. Baiheliang (literally meaning the "White Crane Ridge") is an archeological site in northern Fuling District that has since been submerged underwater due to the building of the Three Gorges Dam. The museum displays centuries-old inscriptions recording changes in the water level of the Yangtze River for around 1,200 years. The site consists of a stone ridge that is 1,600 meters by 15 meters in size. It is now submerged under 43 meters of water. Before the Three Gorges Dam was built, the rock ridge was only submerged during the summer and fall. Every 3–5 years, when the water level of the Yangtze dropped during the winter, the ridge and the carvings on it were exposed and visible. The stone fish figures and inscriptions recording water-levels and other information from the Tang dynasty (618–907 AD) onwards could be viewed by vi
