The Ministère de la Culture's notice

Le site est constitué d'une écluse à sas édifiée au 17e siècle, refaite probablement à l'identique en 1823 (tête amont) et en 1845 (tête aval) et d'une maison éclusière. Il s'agit d'une écluse à aqueducs ménagés dans les bajoyers, dont les vannes sont actionnées par un système de crémaillères. Les trous d'évents en pierre subsistent. Les portes en bois à balanciers ont été refaites en 1993.

The site consists of a chamber lock built in the 17th century, refurbished probably identically in 1823 (upstream head) and in 1845 (downstream head) and a lockhouse. It is a lock with aqueducts created in the lock walls, whose gates are operated by a rack and pinion system. The stone air-vent holes remain. The wooden doors with balance beams were refurbished in 1993.
