Celebrating 30 years of UNESCO heritage on the Canal du Midi
Among the waterways that thread through the Languedoc in southern France, the Canal du Midi is widely regarded as a true jewel; its banks are lined with sunlit paths and filled with centuries of fascinating history and remarkable feats of engineering. In 1996, the Canal du Midi was added to the UNESCO World Heritage list, and in 2026, it will celebrate 30 years of this prestigious recognition. This milestone stands as a testament not only to its historical relevance but also to the extraordinary blend of beauty and ingenuity that defines it.
Through our self-drive boating holidays, we take pride in having played a part in the story of the Canal du Midi, which remains our most popular boating region. Every year, we help people experience just how relaxing, thrilling, and culturally enriching navigating its waters can be. If you’re dreaming of slowing down and savouring the South of France, book your escape today and see the canal from a new perspective.
In today’s article, we’ll revisit some of the key milestones in the history of the Canal du Midi and explore how it continues to inspire us, revealing its remarkable highlights.

Why did the Canal du Midi earn UNESCO status in 1996?
As mentioned earlier, among our canal boating regions in France, the Canal du Midi is the most sought-after. But what makes it so unique to earn a place on the UNESCO World Heritage list? To answer this question, we need to take a step back to the 17th century, when a man named Pierre-Paul Riquet dared to imagine the impossible.
Who designed the Canal du Midi? Pierre-Paul Riquet and the “impossible” engineering feat
Pierre-Paul Riquet wasn’t actually an engineer; he was the King’s tax collector. In the 17th century, France had a bold ambition: to link the Mediterranean Sea with the Atlantic Ocean, while avoiding the waters around Spain, which were then plagued by piracy, storms, and political conflicts. The idea of an inland waterway had existed for centuries, but no one had ever solved the core problem: “where to find enough water to supply a canal running through hilly terrain? Without a consistent water flow, the locks wouldn’t function, the levels would drop, and the canal would fail, hence its reputation as an “impossible project.”
Riquet, however, had a rare combination of practical intelligence, deep knowledge of the French landscape, and sheer persistence. He poured his fortune, energy, and conviction into a plan to capture water from the Montagne Noire and channel it to the canal’s highest point. The result was the Saint-Ferréol reservoir, an extraordinary achievement and the beating heart of the canal. With approval from Louis XIV in 1666, construction began: thousands of labourers, vast earthworks, and hundreds of locks, bridges, and tunnels. The project was completed in 1680, but sadly, Riquet never saw its inauguration, as he died shortly before the Canal du Midi was finished. Today, those same locks and bridges he built still guide boats with surprising smoothness, letting travellers experience his ingenuity firsthand.
The UNESCO designation and the canal’s ‘Outstanding Universal Value’
When the Canal du Midi was added to the UNESCO World Heritage list in 1996, it became one of France’s most celebrated cultural landscapes. UNESCO recognised the canal as an extraordinary feat of engineering, a project that brought together innovation and natural beauty.
The UNESCO designation was based on several Outstanding Universal Value criteria, but in simple terms, the canal earned its place for four main reasons:
- Human ingenuity: it’s a pioneering achievement in hydraulic engineering.
- Exceptional creativity: it’s a brilliant solution to some of France’s toughest geographic challenges.
- Technical innovations: its model influenced subsequent waterways across Europe.
- Living cultural landscape: it’s a place where heritage, nature, and everyday life coexist.
And all of this is undeniably true. Walking along the Canal du Midi today, you come across countless wonders, from characteristic stone bridges to historic locks and quaint villages perfectly integrated with the canal itself. The sense of harmony, enhanced by vineyards that slope gently downwards and quiet mornings filled only with the sound of cicadas, is why travellers, writers, and artists of every kind keep returning.
How to safeguard the Canal du Midi for the next 30 years
Protecting this iconic waterway is just as important as celebrating it. By looking after the canal, we ensure it continues to thrive, safeguarding its wildlife, its history, and the joy of exploring it slowly.
The principal ways the Canal du Midi is being preserved include:
- Replanting the plane trees.
- Maintaining and reinforcing historic locks, bridges, and banks.
- Encouraging slow, responsible travel.
Replanting the plane trees: a living legacy
In recent years, the canal’s iconic plane trees have faced a devastating threat: canker stain, a fungal disease that creates dark streaks in the wood, leads to branch dieback, and can ultimately kill the tree. Thousands of trees have been affected, altering the landscape that so many travellers from around the world have come to know and love. To counter this, a long-term replanting programme is underway, introducing a mix of resilient species selected to restore the historic avenues bring back the shade and beauty of the canal, and create a living legacy for generations to enjoy.
Protecting heritage: locks, bridges, and banks
Safeguarding the canal goes far beyond the trees. Conservation teams work tirelessly to:
- Maintain and reinforce locks, bridges, aqueducts, and banks, keeping these centuries-old structures safe and functional.
- Apply modern engineering solutions to respect the historic character while adapting to today’s environmental challenges.
- Manage water levels and protect biodiversity, with every intervention designed to honour the canal’s unique identity.
- Together, these efforts ensure that people can continue to experience the Canal du Midi as it has been enjoyed for centuries.
How are slow travel, responsible cruising, and self-drive boating protecting the canal?
Not everyone knows that ‘slow travel’ and responsible cruising encourage respect for the structures, waterways, and local communities. As canal boating holiday experts, we know our waterways inside out and are aware that exploring the Canal du Midi at a gentle pace has a real impact on its long-term health. Slow, self-drive boating puts less pressure on banks, wildlife, and the delicate water ecosystem. This allows boaters to enjoy their boating experience while keeping their footprint on the canal to a minimum.
At Emerald Star, sustainability is part of every journey we craft, from mindful navigation to guiding boaters on how to travel lightly, whether they’re new to boating or experts. Every self-drive boating holiday helps protect the canal, showing how adventure and stewardship can go hand in hand.
