Located on China's southeastern coast, the Anping Bridge in Quanzhou, Fujian, is the country's longest surviving cross-sea stone beam bridge. Dating back to the 12th century, it was once a vital link on the Maritime Silk Road and played a key role in connecting inland China to global sea trade. Spanning over 2,000 meters with 361 stone piers, the bridge showcases the remarkable engineering prowess of ancient Chinese builders. Today, it stands as a UNESCO World Heritage Site and a symbol of Quanzhou's rich maritime history.
