The Dujiangyan Irrigation System represents ancient China´s superb science and technology and is a milestone in the world history of water harnessing and irrigation technology advancement.
Built around 256 BC, Dujiangyan is the world´s only and oldest diversion project without a dam. Still in use, it feeds a grid of irrigation canals watering 670,000 hectares of farmland in Sichuan, turning the province into the country´s famous "land of rice and fish" since ancient times.
The weir. The experience and discourse on water control chiseled in the temple is the ancient Chinese people´s scientific summary on conquering nature, and is of great importance to the construct of water control.
Anlan Bridge: It is 500m long and bestrides the inner and the out rivers. The Anlan rope bridge is one of the famous bridgeworks in ancient China. Made of local material, the bridge is refinement in structure. Taking wood as pockets and bamboo as hawsers, the bridge, covered with board, is hung over the river. It is very interesting for visitors to step on the bridge and have a view of the river, which seems as if a boat is flying through the fierce billows.
