Notre-Dame Cathedral · Île de la Cité
The ironwork on the doors was so perfect, the craftsman was accused of a deal with the devil
When Notre-Dame was unveiled, its iron door hinges were so intricate and flawless that medieval Parisians could not believe they were the work of a human craftsman. Rumors spread that the blacksmith Biscornet had sold his soul to complete them. The hinges could reportedly only be opened after being blessed with holy water. Modern metalworkers still cannot fully explain how the work was achieved with 12th-century tools.
