Ferrier of Tannerre-en-Puisaye, Ancient iron mining site in Tannerre-en-Puisaye, France.
The site extends over 30 hectares of forest land, featuring multiple excavation pits and slag heaps reaching heights of 15 meters.
During the Gallo-Roman period, this location operated as the largest iron production facility in Roman Gaul, processing metal through low furnaces.
The medieval fortress Motte Champlay was constructed on the mining grounds in the 10th century to protect the road leading to Paris.
Guided tours explain the iron reduction process through demonstrations in low furnaces, with information panels positioned along designated paths.
The industrial exploitation of iron slag continued until 1982, when authorities designated the site as a protected historical monument.
