A canal listed as a UNESCO World Heritage Site
The Canal du Midi is considered a masterpiece of French engineering, linking Toulouse to the Mediterranean via a waterway running for almost 250 kilometres. The Canal du Midi is now much appreciated by boating tourists, hikers and cyclists. The cycle route beside the canal is still being developed at time of writing.
The Canal du Midi in figures
- 240km in length
- over 14 years in the making (1666 - 1681)
- 350 architectural works constructed, including 63 locks, 126 bridges, 55 aqueducts and 7 canal-bridges
- 12,000 workers were employed on the canal at the height of its construction, these workers using pickaxes and their bare hands to excavate 7 million m3 of earth and gravel.
- Opened to traffic: 1681
An idea from the Roman Empire
The idea of a canal connecting the Mediterranean to the Atlantic was already considered in Roman times. It was an important aim for the Romans to try and move men and supplies from the Med to northwest Europe without having to go all the way round the Iberian Peninsula to reach the Atlantic. Such a route would have allowed them to control their colonies in northwest Europe more easily, both militarily and politically. The technical issues and astronomic costs of such a project thwarted those who wished to turn the dream into reality, from Roman Emperor Nero to 17th-century French king Henri IV.
The oldest canal in Europe still in operation
It was only thanks to the exceptional skills of Pierre-Paul Riquet, in the 17th century, that the project became a reality. Plans for the canal began to take shape in 1662. After some 14 years of work, it was completed in 1681, due to the labours of over 12,000 men and women.
In 1857, the Canal Latéral à la Garonne linking Bordeaux to Toulouse was constructed, allowing boats to cross all the way between the Mediterranean and the Atlantic, avoiding the vast detour around the Iberian Peninsula.

For almost two centuries, the Canal du Midi flourished, used for transporting people and merchandise. The trip by canal between Toulouse and Sète (on the Mediterranean) could last up to four days for passengers and eight days for merchandise.
Up until the arrival of the railway line in the middle of the 19th century, the canal was not subjected to any real competition. With trains, transport by waterway declined slowly, with passenger transport being abandoned to train transport by the end of the 19th century, then freight transport by waterway coming to an end in 1989. Since then, the Canal du Midi, which also serves to irrigate the fields round and about, has been saved by boating tourism (with c.100,000 users a year) and by numerous hikers and cyclists appreciating it.
SOS platanes
Les platanes qui bordent le canal du Midi sont menacés de disparition… Le chancre coloré est un champignon microscopique qui se loge à l’intérieur du platane et bloque ses canaux de sève. Ainsi, il parvient à tuer cet arbre en très peu de temps, entre 6 mois et 5 ans.
La maladie se propage par contact : soit par les racines (très imbriquées), soit par blessure due au frottement des bateau ou au passage de promeneurs à vélo.
La propagation est rapide et malheureusement sans remède. Il n’existe à ce jour qu’une seule solution pour l’endiguer : abattre et brûler les arbres touchés. D’où les campagnes d’arrachage en cours le long du canal. D’autres variétés d’arbres sont peu à peu replantées pour se substituer à ces derniers.
QUELQUES CONSEILS POUR ÉVITER LA PROPAGATION DU CHANCRE COLORÉ
- Ne pas blesser les arbres
- Ne pas graver l’écorce avec un objet pointu
- Eviter de déposer les vélos contre les arbres
- Eviter de s’arrêter sous les arbres secs
- Rester prudent à l’approche des zones de chantier et respecter la signalisation
- Emprunter les déviations mises en place
