The U4 blast furnace is a unique place in France which can be visited and discovered during openings times. Through the various visits, the public will be able to perceive and understand the operation of the factory and grasp, through the testimonies of Mécilor guides, the life of the factory in its technical, historical and human dimensions.

You can visit the Blast Furnace U4 freely, with a guide or audioguide. 

An exhibition created by Mécilor guides will allow you throughout the year to discover the history and the manufacturing process of cast iron.
