Couleurs du passé/Couleurs du présent. La polychromie d’architecture chez Viollet-le-Duc / Colours of the Past/ Colours of the Present. The Polychromy of the Architecture of Viollet-le-Duc

Viollet-le-Duc has always been attentive to the polychromy of the medieval churches. This article proposes to dwell on the technique developed by the architect, with P. Mérimée and J.-B. Lassus, for the preservation and restoration of polychromy. In a second stage, this study focuses on the creation, by the same Viollet-le-Duc, of a new polychromy of architecture, in Pierrefonds in particular, and on the technical reflection that accompanies it.
