La Mine bleue

The slate mine extends 126 meters below ground and features large extraction chambers where miners once worked to extract valuable stone materials.

The mine opened in 1916 through the Ardoisières angevines de Saint-Blaise company and reached peak production of 620 tonnes per month in September 1935.

The underground galleries preserve the mining heritage through exhibitions of tools, personal belongings, and documentation of miners' daily routines from the 1930s.

Guided tours last two hours and require visitors to navigate approximately 200 steps while maintaining a constant temperature of 13 degrees Celsius.

Modern elevators transport visitors deep underground to explore the preserved mining chambers where slate extraction techniques from the early 20th century remain visible.
