The Three Natural Bridges.

The Three Natural Bridges (simplified Chinese: 天生三桥; traditional Chinese: 天生三橋; pinyin: Tiānshēng Sān Qiáo) are a series of natural limestone bridges located in Xiannüshan Town (仙女山镇), Wulong County, Chongqing Municipality, China.[1] They lie within the Wulong Karst National Geology Park, itself a part of the South China Karst-Wulong Karst UNESCO World Heritage Site.[2] In Chinese, the bridges are all named after dragons, namely Tianlong (天龙桥 – literally Sky Dragon) Qinglong (literally Azure Dragon) and Heilong (黑龙桥 – literally Black Dragon).

Description

The Tianlong Bridge.

Spanning the Yangshui River, a tributary of the Wu River, the bridges are at the centre of a Lua error in Module:Convert at line 272: attempt to index local 'cat' (a nil value). conservation area which also includes:

  • Qinglong Tiankeng (青龙天坑);
  • Shenying Tiankeng (神鹰天坑);
  • Yangshui River Karst Canyon (羊水河喀斯特峡谷);
  • Longshui Gorge (龙水峡地缝);

  • Longquan Cave (龙泉洞);

Given that the distance between the upper end of the Tianlong Bridge and the lower end of the Heilong Bridge is only Lua error in Module:Convert at line 272: attempt to index local 'cat' (a nil value)., these are not the longest natural bridges. However, they are the only such group of karst structures in the world.[citation needed] Between the bridges lie the Qinglong and Shenying tiankengs which have a depth of 276–285 metres and a circumference of 300–522 metres.
