The Hunchback of Notre Dame, Victor Hugo’s other famous novel, is set in Notre Dame Cathedral in Paris in the 15th century. The hunchback, Quasimodo, is the cathedral’s bell ringer and he spends most of his life within the confines of the church.
Access to the towers of Notre Dame Cathedral is from the outside of the church in Rue du Cloitre Notre Dame. Visits to the tower start at 10am, but it is a good idea to go earlier as there is often a long queue. It is a long climb to the top (387 steps), but worth it for the close up view of the gargoyles.
