Canal de l’Ourcq

Have you ever wondered why Paris has such a rich history with canals? You see, the Canal de l’Ourcq is the longest of the Parisian canal network, stretching 97 km from Paris to Mareuil-sur-Ourcq. The Canal de l’Ourcq is a key part of the Parisian canal network. This network, consisting of the canals Saint-Denis, Saint-Martin, and of course, the Canal de l’Ourcq, is vital for the City of Paris. While today it primarily serves as a source of non-potable water for the capital, its beginnings are rooted in a much more challenging quest: to provide drinking water to Paris. The city, at the time still struggling with water shortages, needed a solution to quench the thirst of its ever-growing population. This pressing need led Emperor Napoleon Bonaparte to commission the construction of the Canal de l’Ourcq. The canal’s primary function wasn’t just to transport water, but also goods. It was a critical artery for the transportation of wood and grain from the northeast of Paris to the capital itself. The construction of the Canal de l’Ourcq began in 1802, spanning over 20 years. The project was led by the renowned engineer Pierre-Simon Girard, who also played a key role in Napoleon’s campaign in Egypt. The canal’s engineering marvels include a unique two-sloped design and six locks. During its construction, the canal crossed the Seine at the basin of the Arsenal and further merged with the Oise River near Pontoise. The canal’s innovative engineering solved the problem of water stagnation, ensuring that the water transported for drinking was clean. In 1813, the canal saw its first boat journey, carrying goods from Claye-Souilly to the Villette basin. Today, the Canal de l’Ourcq stands as a testament to Napoleon’s vision and innovation. You stand today next to a historical watercourse, an important landmark in Paris, a testament to the city’s remarkable journey.
