Chenglang Weir

Chenglang Weir

Chenglang Weir is located at the confluence of the Fenghua River and Nantang River on the north side of Chenglang South Road in Haishu District, Ningbo. In August 2003, it was designated as one of the third batch of municipal-level cultural heritage protection sites in Ningbo. Initially built in the first year of the Kaixing era of the Southern Song Dynasty (1259), it has been renovated in various dynasties, with the current structure mainly reconstructed during the Qing Dynasty. During the Song and Ming Dynasties, it was known as “Zhenglang Weir,” “Zhengjia Weir,” and “Zheng Shiba Lang Weir.” In the Southern Song Dynasty (1259), it was rebuilt under the supervision of Wu Xiong, originally as an earthen weir and later reconstructed as a stone one. The weir is built with strip stones, featuring a sluice gate on the dam. The upper part has been replaced with reinforced concrete and equipped with tracks. On the north bank of the weir, there is a management building constructed in 1959. Currently, the weir is submerged underwater for preservation.

Chenglang Weir is an important historical hydraulic transportation hub in Ningbo, providing physical evidence for the study of ancient water conservancy projects in the city.
