Le Fer en Héritage(s) is a substantial Lorraine heritage exhibition set inside the Abbaye des Prémontrés in Pont-à-Mousson, a town whose modern story is deeply linked to iron, foundries and industrial work. Built around the centenary of Camille Cavallier, the exhibition follows the region’s iron from its geological origins in the minette lorraine through extraction, steelmaking, technical innovation and the rise of major industrial families and companies. Its strongest value is regional: this is not a generic art display, but a readable portrait of how Lorraine’s landscapes, towns, labour culture and economic memory were shaped by mines, blast furnaces, workshops, archives and workers’ lives. The abbey setting gives the subject extra weight, connecting monumental heritage with the industrial heritage that still defines much of Lorraine’s identity.
