Gazing down Boulevard Carnot, imagine a bustling street lined with vibrant flowers. This wasn’t always Boulevard Carnot. It was once called Rue des Fleurs, a much narrower, less grand thoroughfare. In 1906, a dramatic transformation began, reshaping not just the street but the very heart of Lille. Boulevard Carnot emerged, wider and more imposing, stretching from the Place du Théâtre to the old city walls. This wasn’t just a cosmetic change. It was part of a grand vision to connect Lille to Roubaix and Tourcoing with a magnificent 50-meter wide avenue, complete with rapid tram lines.
Boulevard Carnot quickly became a symbol of Lille’s modernization and ambition. This ambitious project came at a cost. Several historic streets, like Rue des Oyers, Rue des Suaires, and Rue du Bois Saint-Étienne, vanished. The Place des Guingnants met the same fate, making way for the new boulevard. The area around Boulevard Carnot also boasts a rich academic history. The former convent of the Récollets, founded in 1249, housed the central school, which later became the municipal college of Lille. In 1852, after significant renovations, it was designated the “Lycée Impérial”.
This building, facing Boulevard Carnot, played a crucial role in the development of science in Lille. In 1854, Louis Pasteur himself established the Faculty of Sciences within its walls, sharing the space with the preparatory school of medicine and pharmacy. This marked a significant moment for Lille, placing it on the map of scientific innovation. The Faculty of Sciences eventually outgrew its home on Boulevard Carnot. In 1894, it relocated to the Saint-Michel district. The original building then became Collège Carnot in 1964. It continues to educate students to this day.
Boulevard Carnot was more than just an educational hub. It also served as a vital transportation artery. The southern end of the boulevard was the terminus for the Lille-Roubaix-Tourcoing tramway, a revolutionary system designed by Alfred Mongy and inaugurated in 1909. The tramway looped around the opera house, a striking visual element that further enhanced the boulevard’s grandeur. In 1983, this terminus was moved underground to Lille-Flandres station, connecting to the metro. The modern Boulevard Carnot still echoes its past. As you stroll along its wide sidewalks, remember the vanished streets, the bustling tramway, and the scientific breakthroughs that once filled the air. Boulevard Carnot is a testament to Lille’s ambition, a street that whispers tales of transformation, innovation, and connection.
