The Trèbes locks are a flight of locks composed of three basins. Built around 1674, it is located downstream from the port of Trèbes at the exit of the town in the direction of the village of Marseillette. Taking advantage of the significant drop in the flight of locks, intense milling activity was established on the left bank of the lock. A first upper mill was built at the end of the 17th century. It is crossed by a diversion of the Canal du Midi which ensures its operation; it is described as having four millstones with a stable and a shed. A transformation of this first mill was carried out in 1867 to make it a mill with 6 millstones. This new building, later enlarged in the 1930s, consists of a basement and 4 floors at its highest point. It has today been converted into a restaurant.
