Jianshui Shuanglong Bridge

Jianshui Shuanglong Bridge

Jianshui Shuanglong Bridge is a National Key Cultural Relics Protection Unit.

Shuanglong Bridge, commonly known as the "Seventeen-Arch Bridge," is a grand three-pavilion, seventeen-arch stone bridge. It is located five li west of the ancient city of Jianshui, spanning the confluence of the Lujiang and Tachong rivers, and is one of Yunnan Province's renowned historical sites, having been recorded in China’s bridge-building history.

Shuanglong Bridge is located on the Lujiang and Tachong rivers, three kilometers west of Jianshui City. It earned its name because the two rivers wind like dragons, and is commonly known as the "Seventeen-Arch Bridge." This is a three-pavilion, seventeen-arch stone bridge, stretching 148 meters in length and 3 to 8 meters in width. It is one of Yunnan Province's most famous historical sites and is considered the largest and most artistically valuable multi-arch bridge in the province. It has been recorded in China’s bridge-building history. The bridge features three flying-eave pavilions in the center, creating a layered effect of towers upon towers, with the bridge and towers complementing each other in a magnificent sight — truly a rare masterpiece in China’s bridge-building history. The two end pavilions are slightly smaller, while the central one is grand and imposing, often referred to as the "Grand View Pavilion of Southern Yunnan." In 1965, the renowned Chinese bridge expert Mao Yisheng visited and designated it as one of the country’s major ancient bridges, after which it was listed as a Key Cultural Relics Protection Unit of Yunnan Province.

Historical Background

The term "Shuanglong" (Double Dragons) refers to the convergence of the Tachong and Lujiang rivers, with a single bridge symbolically restraining the "two dragons," hence the name. Originally built during the Qing Dynasty’s Qianlong era, Shuanglong Bridge on the Lujiang River, three li west of Jianshui City, initially consisted of just three stone arches over the Lujiang. Later, due to flooding and the widening of the riverbeds of both the Lujiang and Tachong, the small three-arch bridge stood isolated in the middle of the river and could no longer span both banks. In the 19th year of the Daoguang reign (1839), local officials and residents added fourteen more arches, connecting them seamlessly with the original three, forming a continuous structure — hence it also became known as the "Seventeen-Arch Bridge." The bridge stands 9 meters high. The original three arches were 5 meters wide, while the later fourteen arches are 3 meters wide. The entire bridge is 148 meters long and constructed from about 500 precisely cut stone blocks, with stone railings on both sides. Three flying-eave pavilions were also built atop the bridge. The two end pavilions are smaller, while the central one is larger and more majestic, often called the "Grand View Pavilion of Southern Yunnan." During the Xianfeng era, the bridge was completely destroyed in war. In the 24th year of the Guangxu reign (1898), the three flying-eave pavilions were rebuilt on an even grander scale than the original ones. The bridge features three pavilion towers with overlapping layers and interlocking eaves. As noted in the inscriptions: “The bridge is adorned with three flying pavilions. The central one has two stacked levels, reaching toward the clouds. Together with the flanking two pavilions, they reflect each other brilliantly, presenting a majestic western view!” The famous bridge expert Mao Yisheng included Shuanglong Bridge in his monograph “The Diverse and Magnificent Ancient Bridges of China” among the top ten representative ancient bridges in the country, and also featured it in his monumental work “The History of Ancient Chinese Bridge Technology,” devoting a special section to both Shuanglong Bridge and the Seventeen-Arch Bridge in Beijing’s Summer Palace.

Architectural Features

From a distance, Shuanglong Bridge rises prominently amid the vast plains of Jianshui’s western basin, with its seventeen arches lined up in a row, each connected seamlessly. The bridge spans 148 meters in length and 3 to 5 meters in width, standing majestically and beautifully like a rainbow lying across the waves. Its reflection shimmers in the water merging with the sky. The towering pavilions, surrounded by green fields, resemble a grand ship floating gently on a tranquil lake. As we approach the arched bridge, we can observe the exquisite craftsmanship of the pavilions atop it — towers within towers, eaves beyond eaves. Walking slowly across the bridge feels like strolling through elevated passageways in the sky. The Lujiang and Tachong rivers rush from afar, converge beneath the bridge, and then flow away powerfully. Stepping into the bridge’s pavilions, one can further appreciate its unique design, exquisite craftsmanship, and harmonious layout. The smaller pavilions are double-eave, pyramidal-roofed structures with upturned corners. The large central pavilion is a square, three-eave main tower with stacked and interlocking eaves. Climbing up, visitors can admire the finely carved lattice windows and screen doors inside, featuring intricate designs of flowers, birds, dragons, and deities. These details are sure to leave one in awe of the exceptional skill of ancient artisans.

Shuanglong Bridge is the largest and most artistically valuable multi-arch stone bridge among ancient bridges in Yunnan. It inherits the characteristics of traditional Chinese bridge architecture, blending engineering science with aesthetic design. It embodies the advanced techniques and ingenuity of the people of southern Yunnan. With its remarkable scale and artistic value, it stands out nationally and is a masterpiece in the history of ancient Chinese bridges, holding an important place in China’s bridge-building heritage.
