An exceptional remnant of the Briare Canal, the Moulin-Brûlé lock staircase features four 17th-century lock chambers and the only swing bridge with a pivoting deck still standing on the canals of the Loiret.

History
Nestling in the Loing valley at Dammarie-sur-Loing, the Moulin-Brûlé lock scale is one of the most precious hydraulic testimonies to the history of French canals. This discreet but fascinating site offers visitors a direct insight into the technical prowess of river engineering in the Grand Siècle, far from the crowds that flock to the great châteaux of the Loire. The ensemble forms a veritable architectural palimpsest, superimposing the traces of four centuries of mastery over water. The four joined locks, built between 1604 and 1642 using a system developed by Hugues Cosnier, rise in successive tiers to overcome a significant difference in level. This series of locks was a pioneering technique in its day, and foreshadowed the great hydraulic engineering works of Europe. Enlarged and lengthened around 1830 to meet the demands of growing commercial traffic, these locks were finally replaced by a new reach below around 1885-1890, leaving the site in a particularly moving state of temporal suspension. What really sets the Moulin-Brûlé apart from all the other sites on the Briare Canal and its neighbouring canals is the presence of the only swing bridge with a pivoting deck still preserved on all three canals studied. Built in 1887, shortly before the site was abandoned, this ingenious metal structure rotates around a vertical axis while raising its deck slightly to allow the tow rope to pass through without breaking the traction of the horses or men. It's a remarkably ingenious detail, almost poetic in its pragmatism. The lock-keeper's house, built as an extension of this history, adds a human dimension to the site. Altered several times in the 19th century, it has preserved a partly buried lime kiln, a likely reminder of the craft activities that once kept the canal banks alive. Much of the site has now been reclaimed by riverside vegetation, giving it an intimate, bucolic atmosphere that will appeal as much to those with a passion for the history of techniques as to those who enjoy walks along the water.
Architecture
The Moulin-Brûlé lock scale belongs to the type of joint locks, a system consisting of several consecutive lock chambers separated by short intermediate reaches, or even directly adjoining each other. The four locks are set on a gentle slope, their local limestone walls forming a mineral corridor that runs alongside the towpath. The original arched gates, made of oak wood reinforced with ironwork, have been replaced over the centuries by more modern equipment, but the 17th-century masonry remains visible in the lower sections of the lock chambers. The widening and lengthening of the 1830s can be seen in the stonework: the more regular courses and lime renderings characteristic of the building sites of the first half of the 19th century stand out from the more irregular and robust masonry of the Grand Siècle. The lock-keeper's house, which has also undergone several alterations, has a modest, functional layout typical of service accommodation on the royal canals. As an outbuilding, the semi-buried lime kiln, with its partially preserved barrel vault, bears witness to the additional craft activities that were essential for maintaining the canal. The 1887 swing bridge is the technical centrepiece of the complex. Made of wrought iron and cast iron, its deck rests on a central axle mechanism that allows horizontal rotation while inducing a slight vertical lift of around forty centimetres. This mechanical subtlety - rare for a rural road structure - testifies to the level of sophistication achieved by canal engineers at the end of the 19th century, anxious to reconcile the practicality of towing with the fluidity of navigation.
