????Shihu Dock is an outer port dock at Quanzhou Bay, composed of Tongji Bridge and the dock built with natural reef rock. Between 713 and 741 (during the Kaiyuan period of the Tang Dynasty), maritime merchant Lin Luan built stone staircases on seafront slopes and used natural rocks to build a dock. Between 1086 and 1094 (during the Northern Song Dynasty), an official named Fu Jin built Tongji Bridge to connect seafront villages with the rock dock, thus forming up a coast-wise dock for ship mooring. It is a south-north L-shaped structure, with a total length of 113.5m, a width of 2.2m and a height of 2.41m, including a 70m-long bridge. The dock is crisscross paved with granite slabs layer by layer, presenting a masterpiece of early dock architecture that exhibits scientific design and remarkable durability. It was an important offshore dock of Zayton Port used as the infrastructure for both maritime trade and coastal defense during the Song and Yuan dynasties and has been in use to this day.
