The first construction of the Precious Belt Bridge, a Chinese stone arch bridge located at the intersection of the Grand Canal and Dantai Lake, about 2.5 kilometer southeast of Suzhou in present Jiangsu Province, China, dates back to the CE 816, during the middle Tang Dynasty.

According to written accounts, the bridge derives its name from the local prefect Wang Zhongshu, who in a selfless act had sold his precious belt in order to help finance its construction.

Since then, it has been reconstructed several times.

The current structure of the Precious Belt Bridge is a Ming Dynasty era reconstruction of 1446, during the reign of the Zhengtong Emperor.
