The 'blue' in the name refers to the deep blue-grey color of the high-quality slate extracted from these specific deposits.
The mine is located in the heart of the historic Anjou slate basin, which provided materials for many of the region's prominent chateaux roofs.
Operations in the underground galleries ceased in the late 20th century, leading to its transformation into a preserved heritage site.
The descent involves a mining cage that mimics the authentic experience of the workers who once labored here.
The rock extracted here is considered some of the finest slate in France, characterized by its durability and fine grain.
La Mine Bleue is a former slate mine located in Segré-en-Anjou Bleu that offers visitors a descent 126 meters underground to explore historical mining tunnels. The site showcases the extraction techniques used to harvest Anjou slate, a rock formed over 450 million years ago. A trip to the mine begins with an industrial cage elevator ride, followed by a journey through the galleries via a miniature train. The subterranean environment maintains a constant year-round temperature of 13 degrees Celsius. Visitors observe the original work areas and equipment left behind by miners who operated the site. The museum portion of the visit documents the daily life, risks, and economic impact of slate mining on the local region. It stands as a rare example of a heritage site dedicated to the industrial history of the Blaison-Gohier and Segré slate basins.
