Canal du Midi
Occitanie
The Canal du Midi is a remarkable 240-kilometer long canal in Southern France, originally constructed between 1666 and 1681 under the supervision of Pierre-Paul Riquet and authorized by Jean-Baptiste Colbert during the reign of Louis XIV. It connects the Garonne River at Toulouse to the Étang de Thau near the Mediterranean Sea, forming part of the Canal des Deux Mers which links the Atlantic Ocean to the Mediterranean. This summit-level canal rises to the Seuil de Naurouze, its highest point at 189 meters altitude, overcoming significant engineering challenges including water supply from the Montagne Noire. With an average surface width of about 20 meters and a depth designed for navigation, it remains one of Europe's oldest operational canals. Its exceptional design and historical significance led to its inscription as a UNESCO World Heritage Site in 1996 and designation as an International Historic Civil Engineering Landmark in 2016. Today, the canal is a popular route for leisure boating and tourism, showcasing beautiful landscapes, historic locks like the Fonserannes, and charming towns such as Castelnaudary and Carcassonne along its course. The Canal du Midi is not only an engineering masterpiece but also a cultural symbol of the region's heritage and waterways.

History
Construction of the Canal du Midi began in 1666 following a royal edict by Louis XIV and was completed in 1681 under the direction of Pierre-Paul Riquet.
The canal was originally named Canal Royal en Languedoc but was renamed Canal du Midi during the French Revolution in 1789.
It was designed to facilitate wheat trade and inland navigation, overcoming the challenge of supplying water to its highest point, the Seuil de Naurouze, from the Montagne Noire.
Over the centuries, the canal has maintained its importance, later extended by the Canal latéral à la Garonne to connect the Atlantic and Mediterranean seas.
Its unique legal status was codified in the mid-20th century, and it is managed by the French state through Voies Navigables de France.
