The Briare Canal (, ) is one of the oldest in France. Its construction started in 1604. It was the first summit level canal in Europe that was built using , connecting the Rhone-Saône and Seine valleys. It is long and is part of the Bourbonnais route from Saint-Mammès on the Seine to Chalon-sur-Saône on the Saône.
From Briare to Buges, the canal rises through the first 12 locks some and then falls through the remaining 24 locks.
After Henri IV's assassination, Hugues Cosnier had to give up work in 1611. In 1638, Guillaume Boutheroue and Jacques Guyon applied to resume work, and received letters patent from Louis XIII for this purpose. They created with other nobles the Compagnie des seigneurs du canal de Loyre en Seine and work was completed by 1642.
Reservoirs were dug to supply the approximately 2000 cubic meters of water displaced at each lock. They include the reservoirs of Turfs, Chesnoy, Grand-rû, Tilery, Du Chateau, Cahauderie, Beaurois, the Bourdon reservoir, and the Moutiers reservoir on the Loing. The original source of water was the Étang de la Gazonne.
Shortages of water in the reservoirs and Loire valley often resulted in 2–3 months closure per year.
In periods of drought the canal's reservoirs were insufficient to keep the canal full of water, therefore in 1894 and 1895 a pumping station was built to pump water into the summit pound.
The Briare aqueduct built over the Loire in Briare between 1890 and 1896 by the engineer Abel Mazoyer is part of the Canal latéral à la Loire, and replaced the old line of that canal, built between 1820 and 1830.
