Barrage éclusé de Port-à-l'Anglais

The Port-à-l'Anglais complex is a lock and dam system on the Seine featuring two separate locks and three water control passages. This structure allows water levels to be managed while enabling boats to travel safely through this section of the river.

The first lock and dam were built between 1861 and 1864 as part of Napoleon III's infrastructure development program. A second lock was added in 1881 to handle increased river traffic.

The name comes from the Langlois family, who once ran a farm and port operation along this stretch of the river. Over time, 'Port à Langlois' became known as 'Port à l'Anglais'.

The complex can be viewed from both riverbanks, and adjacent pathways let visitors walk between Vitry-sur-Seine and Alfortville. Visit during daylight hours to see the locks operating and watch boats passing through.

In 2012, the facility received permission to generate hydroelectric power by installing turbines within its existing structure. This transformation turned it into both a working power plant and a functioning navigation system.
