The Napoleon quarry (Ferques, France)

In the Ferques / Marquise region there are some large quarries. In Marquise you have rather softer limestone, while in Ferques you will find the harder marble. One of the most famous (and the largest in France) are the "Carrières du Boulonnais". This one is located along the D231 where they have created a nice viewpoint. From there you have a view of the big "Carriere Napoleon". The pictures below make it clear what can be seen: one big hole in the bottom of the Earth. This is where marble is mined that was used in numerous city halls, churches, hotels, etc. worldwide. "Napoleon" here refers to a well-defined type of marble. More than 85% of the production is for export. A spectacular viewpoint you must have seen if you are in the area.

Company visits are available from June 2025. See this web site.
