Origin and history

The Longuyon blast furnace, located in the municipality of the same name in Meurthe-et-Moselle (Great East region), is an industrial vestige dating back to the 17th century. This site, partially rebuilt in the 19th century (more precisely in the 2nd quarter of the 19th century), illustrates the importance of metallurgy in this historically steel-rich region. The remains still visible today, protected by a registration order in 1982, offer a material testimony of the techniques of production of cast iron before the industrial revolution.

The location of the blast furnace in the department of Meurthe-et-Moselle is part of a territory where iron ore mining and metallurgical processing have played a major economic role since the modern era. The reconstruction of the site in the 19th century coincided with a period of modernization of industrial infrastructure in Lorraine, then integrated into expanding production and transport networks. Although the sources do not specify the exact actors involved in this reconstruction, the inscription of the monument in 1982 highlights its heritage value as an example of early industrial architecture.

Today, the Longuyon blast furnace, whose only remains remain (including the Cadastral A 4), is a Historical Monument accessible to study or visit, although current practical information (opening, services) is not detailed in available sources. Its state of conservation and location, considered "a priori satisfactory" (note 6/10), make it a site of interest for technical and regional history, anchored in the landscape of Lorraine steel.
