Its story
For centuries, ancient kings dreamed of connecting the Atlantic to the Mediterranean. It wasn’t until the 17th century that a man from Béziers found the key to solving this problem in the waters of the Black Mountains.
Its construction, under King Louis XIV, was just as monumental as its tumultuous history that went on for more than three centuries. Over 15 years, with the help of 12,000 men and women, 240 kilometers were dug from Toulouse to Marseillan.
Once it was finished, local products from across the region could be transported to Paris: grain, salt, wine, pink marble, etc. From 1730 to 1858, the canal experienced its glory days: its regularity, comfort, safety and speed (4 days from Toulouse to Sète) commanded admiration.
But the life of the canal du Midi would never be clear sailing… It became filled with silt, which required Vauban to step in. In the 19th century, the canal then faced competition from trains, which almost proved fatal…but not quite!
The last transport boats were quickly replaced by recreational boats, mainly from Great Britain, which gave a second life to the canal through river tourism.

Pierre-Paul Riquet, creator of the canal
His nickname was “the Moses of the Languedoc.” It is to Pierre-Paul Riquet, a self-taught bourgeois from Béziers, that we owe the construction of the canal du Midi. His genius and perseverance enabled him to carry out the work of a lifetime.
Pierre-Paul Riquet showed his ingenuity in discovering how to supply water to the canal “connecting the two seas.” Drawing on his extensive knowledge of the land, he unlocked the potential of the Black Mountains’ abundant waters!
During the 15 years of construction, this simple tax farmer responsible for collecting and administering the salt tax (gabelle) in Haut Languedoc demonstrated his genius, perseverance and skill to King Louis XIV and his superintendent, Jean-Baptiste Colbert. Riquet even went so far as to dig the Malpas tunnel, against the king’s advice, just to prove that it could be done! Driven by his desire to restore former titles of nobility, he proved to be something of a workaholic and a talented builder.
Pierre-Paul Riquet died on October 1, 1680 in Toulouse, without having seen the completion of his work… There were only 4 kilometers of the canal left to build. His most impressive works were produced in the final years of his life: the Répudre Aqueduct navigable water bridge, (the first of its kind in the world!), the majestic 25 meter-high water staircase in Fonseranes and the unlikely Malpas tunnel.
Château de Bonrepos
It is here, north of Toulouse, that Riquet conducted his first experiments to find the best water supply system for the future canal du Midi.
UNESCO classification
In 1996, the canal du Midi was classified as a World Heritage Site by UNESCO, thus confirming its exceptional universal value!
The canal du Midi is the only French landmark on the list to meet four of the ten required criteria:
- “to represent a masterpiece of human creative genius”
- “to exhibit an important interchange of human values”
- “to be an outstanding example of a type of building, architectural or technological ensemble”
- and “to be an outstanding example of a traditional human settlement.”
The canal du Midi is considered the largest civil engineering structure with no less than 350 components, including 63 locks, 126 bridges, 55 aqueducts, 7 canal bridges, 6 dams, 1 spillway and 1 tunnel!
The canal du Midi is classified in its totality, i.e. for its public river domain and feeding system as well as its landscapes. This includes its famous plane trees, which are a valuable part of the canal’s heritage and biodiversity.
Travel
on the canal du Midi
The canal du Midi is a waterway like no other. This symbol of human achievement has revolutionized river transport in the Languedoc area. As a UNESCO World Heritage Site, the canal du Midi is now a major tourist attraction in the Occitanie region. Climb aboard and set sail!
Going with the flow
Visiting the entire canal du Midi takes a considerable amount of time. You could easily spend your whole holiday discovering all it has to offer. But you can also choose to visit just certain parts of the canal. Whatever your preference, there are many must-see locations along the canal du Midi. These include: the Port de l’Embouchure in Toulouse, the Seuil de Naurouze watershed, the Grand Bassin of Castelnaudary, the Orb Aqueduct, the Fonseranes Locks, the Somail, the Malpas Tunnel, and more.
"The canal joining the seas is without doubt the most beautiful and most noble construction of its kind ever undertaken. I would have preferred to have created it, than all that I have done and all that I will do."
