Anhui Yuliang Dam

• The Yuliang Dam stands as a testament to ancient engineering, nestled in Yuliang Village just 1 kilometer south of Shexian County in Anhui, China. Initially erected in the Tang Dynasty, it underwent significant reconstruction in 1605 AD during the Wanli period of the Ming Dynasty. Spanning about 140 meters in length, this historical dam boasts a sturdy base of 27 meters wide, tapering to a 4-meter width at the top.
• Crafted from heavy bluestone slabs each exceeding a ton, the dam's construction features a unique interlocking technique. Silver pins are meticulously inserted, both interlayer and vertically, ensuring the structure's durability and integrity. At its heart lies a central drainage gate, a crucial element for water regulation.
• Serving more than just an agricultural purpose, the Yuliang Dam was pivotal for commerce, acting as the primary embarkation point for Huizhou merchants during the thriving Ming and Qing Dynasties. It not only controlled the flow of the upstream river but also smoothed the path for boat travel to the flourishing provinces of Zhejiang and Jiangsu.
