The Château de Blâmont is a castle built at the end of the 13th century in the French commune of Blâmont, in the département of Meurthe-et-Moselle. It underwent successive alterations and extensions in the 13th, 14th and 17th centuries which have made it one of the most beautiful medieval castle ruins in Lorraine, thanks to the preservation of five towers. Château de Blâmont is listed as a monument historique by the French Ministry of Culture.
