The Yanguan fish-scale stone seawall is located in the park of the famous tide-watching resort, about 1,000 meters away from the Zhan’ao Tower. The fish-scale stone seawall was built to prevent the tide disaster of the Qiantang River. It was built more than 1,700 years ago. During the reign of King Qian (疒占) of Wu and Yue in the Five Dynasties, a large number of masons were recruited to build the seawall on a large scale. Since then, it has been repaired in successive dynasties. The fish-scale stone seawall is entirely made of neat rectangular stones in a ‘T’ shape and is stacked in sequence from bottom to top. To solve the technical problems caused by the scouring and dredging of the seawall body by the Qiantang River current, each stone is pasted and grouted with glutinous rice with strong stickiness, and then fastened with iron cramps and tenons. Iron ingots are used on the top of the stone seawall to prevent loosening. Earth mounds are added behind the seawall to protect it. Looking at the seawall body from the side, the layers are arranged like fish scales, neat, beautiful and firm. Therefore, it is called ‘fish-scale stone seawall’. Up to now, the fish-scale stone seawall still plays a very important role in water conservancy and is also known as the ‘Great Wall against the sea’. Opening hours: Open all year round from 08:00 to 16:30.
