The world is mourning the fire-ravaged Notre Dame cathedral in Paris. Built over a 200-year period between 1163 and 1345, the cathedral has periodically lapsed into disrepair over the centuries. Here are photographs taken in the 1860s, when photography was a new medium and the cathedral’s spire had been recently restored.
The Prints and Photographs Division also has one of Viollet le Duc’s books about his restoration of Notre Dame, which included providing the new spire. The entire book is online.
