For the visionary French architect Eugène-Emmanuel Viollet-le-Duc (1814–1879), to draw was not merely to represent the world—it was to understand, dissect, and reimagine it. Today best known for restoring some of France’s most iconic medieval monuments, including Notre-Dame de Paris, Viollet-le-Duc was also a prolific draftsman who placed drawing at the center of his wide-ranging practice. With pen and pencil, he scanned the anatomy of cathedrals, mapped geological formations, and gave life to an imagined past. This online exhibition is a companion site for the first major exhibition in the United States dedicated to this towering figure of modern architecture—and the first to explore the primacy of drawing in his transformative career.
