The technical and scientific objects and documents of the Centre Historique Minier are still not well known to the general public, even though they have played a leading role in the technological progress and knowledge of the mining industry.

Unusual in form and design, they reflect the technical expertise that has enabled mining to develop. During a trip to Lewarde, the public has the privilege of discovering all their specificities.
