Located in Xiannvshan Town, Wulong District, Chongqing, the Wulong Three Natural Bridges site is a rare World Natural Heritage site and a National 5A-rated tourist attraction. It features the largest cluster of natural stone bridges in Asia, comprising three magnificent, naturally formed stone arches: Tianlong Bridge, Qinglong Bridge, and Heilong Bridge. Spanning the Yangshui River Gorge, these bridges connect two world-class karst sinkholes—Tianlong Sinkhole and Shenying Sinkhole—creating a breathtaking karst landscape characterized by "three bridges flanking two sinkholes."
Beyond its geological significance, the site is also a favorite for major motion pictures. "Tianfu Official Posthouse"—the sole exterior filming location for Zhang Yimou’s *Curse of the Golden Flower*—is nestled at the bottom of the sinkhole, and the site also served as an iconic filming location for *Transformers: Age of Extinction*.
