When the popularity of Victor Hugo’s novel The Hunchback of Notre Dame drew attention to the church, the state hired architect and preservationist Eugène Viollet-le-Duc to restore it. His renovation, which lasted from 1844 to 1864, modified the cathedral: he added the spire, gargoyles, and griffins. Charles Soulier shows us the church’s front and some of the surrounding neighborhood, bustling with carriages and new construction.
