Barrage de Poses, Navigation dam and lock system on Seine River in Poses, France
The dam structure extends 235 meters across the Seine River, featuring six water passages and metal beams with concrete cladding.
Engineer Édouard Caméré designed and constructed the dam between 1878 and 1881, with its official inauguration taking place on July 3, 1887.
The Seinoscope observation chamber provides visitors with underwater views of migratory fish species through three glass windows beneath the water level.
Seven lock keepers manage the site operations continuously, processing approximately 40 boats daily through the lock system.
A hydroelectric power station added in 1991 contains four turbines generating 8 megawatts of electricity using the water flow.
