Three Natural Bridges


The Three Natural Bridges are a series of natural limestone bridges located in Xiannüshan Town, Wulong District, Chongqing Municipality, China. They lie within the Wulong Karst National Geology Park, itself a part of the South China Karst-Wulong Karst UNESCO World Heritage Site. In Chinese, the bridges are all named after dragons, namely Tianlong Qinglong and Heilong.

Description

Spanning the Yangshui River, a tributary of the Wu River, the bridges are at the centre of a conservation area which also includes:
Given that the distance between the upper end of the Tianlong Bridge and the lower end of the Heilong Bridge is only, these are not the longest natural bridges. However, they are the only such group of karst structures in the world. Between the bridges lie the Qinglong and Shenying tiankengs which have a depth of 276–285 metres and a circumference of 300–522 metres.
