Xianren Bridge

Xianren Bridge is a natural limestone arch spanning the Buliu River in northern Guangxi. The arch measures 121.9 meters across, making it the longest documented natural arch span in the world.

The formation remained unknown until 2009 when it was discovered through satellite imagery. A scientific survey in 2010 confirmed its record-breaking size and documented its measurements.

Local people call the structure Fairy Bridge, connecting it to Chinese traditions of linking natural formations with mythical ideas. This name reveals how the landscape has found a place in the area's folklore and imagination.

To reach the bridge, visitors must take a three-hour boat journey down the Buliu River. Local guides are familiar with the best conditions and timing for viewing the formation safely.

The arch remained completely unknown until satellite imagery revealed it by chance during routine monitoring. This surprising discovery shows how remote regions can hide extraordinary features that escape human notice for centuries.
