In the water town of Nanling, the Zhanghe and Hougang rivers converge. Locals historically called this confluence the "Meeting of Dragons." Spanning this exact point is the Nanling Longmen Bridge, a fifty-five-meter stone arch structure that has anchored the region's geography since 1584. Financed by local gentry and commissioned by a Ming Dynasty magistrate, the bridge originally served as a crucial artery on the main road to Huizhou and Mount Huangshan. For centuries, it carried merchants, scholars, and travelers over its five circular arches.

In its early days, the bridge supported elaborate wooden pavilions. The Kuixing Pavilion, added in 1608, and the later Wenlan Pavilion offered travelers a place to rest above the water. Ming and Qing dynasty poets frequently wrote about the structure, describing it as a "jade dragon" resting on the waves. Those pavilions burned down during the mid-nineteenth century, leaving the bare stone arches we see today.

The bridge is built from massive, solid stone blocks. Four heavy piers support the five arches, with the central span reaching ten meters across. Stone railings line the deck. Originally, two pairs of carved stone lions guarded the entrances. Today, a single intact lion remains on the western approach, watching over the water, while the eastern figures have worn away with time.

As the twentieth century progressed, the bridge adapted to new demands. In 1952, workers reinforced the deck and paved it with asphalt to support motor traffic on the regional highway. Eventually, shifting river channels and the construction of modern concrete bridges diverted heavy vehicles away from the aging stone structure. Recognizing its historical weight, the provincial government designated the bridge a protected cultural site in 2019. A comprehensive restoration completed in 2024 stabilized the arches, repaired the stone railings, and cleared the waterways. Today, the Longmen Bridge carries occasional local foot traffic, standing quietly as a permanent fixture in Nanling’s changing landscape.
