Lezennes: Quarry History and Lac Bleu

For travelers interested in history and culture, Lezennes is best explored through its underground quarries. They bring together an almost thousand-year history of stone extraction, geological features, a local biography, and former cultivation. If you are looking for a hotel in Lezennes, this theme gives the town a distinctive cultural profile. Highlights include Lac Bleu, stalactites, Lezennes stone, and traces of its use in Lille.

Lac Bleu and geological features

Lac Bleu is an underground lake in the underground quarries of Lezennes. It formed when groundwater flooded some of the passages. Stalactites also form in the galleries: droplets of water deposit calcite on the ceilings. The lake and stalactites thus represent different natural processes within the quarries—flooding in some passages and the deposition of calcite by droplets. In addition to their historical and cultural significance, the quarries are also part of Lezennes’ natural heritage.

From Lezennes stone to buildings in Lille

The quarries have an almost thousand-year history. Lezennes stone was extracted here and used in numerous buildings in Lille. These include the Citadel, the Palais Rihour, the Hospice Comtesse, the Vieille Bourse, and the Porte de Paris. This connection spans the journey from local extraction to the use of the material in buildings in the city of Lille. For travelers interested in architecture and the origins of building materials, it offers an additional perspective on Lezennes’ history: the town’s name is also linked to buildings beyond its own quarry area.

Isidore Court'Orelle and work in the quarry

A local biography offers a glimpse into quarry work: Isidore Court'Orelle was a young quarry worker. He learned to extract white stone in the Catiches typical of the region. The town’s history therefore includes not only the stone that was extracted, but also the work involved in quarrying it. In 2000, the town of Lezennes created its own giant figure, Isidore Court'Orelle. These two associations—the young worker and the town’s giant figure—give the name a historical as well as a cultural context in Lezennes.

Cultivation in abandoned passages

The quarries were used for more than just extracting stone. Around 1860, Isidore Court'Orelle grew Barbe de capucin, a winter salad, in abandoned passages. The cultivation of mushrooms and Barbe de capucin is also associated with the underground quarries. Their history therefore encompasses several uses: stone extraction shaped the town’s long past, while abandoned passages were also used for cultivation. The winter salad also anchors this history in a specific local tradition.

Tours and travel planning

Since 1999, the Lezennes municipal council and its Comité de la Pierre have organized quarry tours as part of the Journées du Patrimoine. If you would like to include a tour in your trip, check the program for the relevant Journées du Patrimoine. Together, Lac Bleu, stalactites, stone extraction, architectural history, and former cultivation offer different ways to explore Lezennes’ heritage. When choosing your destination, you can decide whether geology, the history of stone, or local culture is of greatest interest to you.
