The Basilica of Saint Genevieve became the Panthéon under the French Revolution, and was formerly a lighthouse and a cave. Famous for its dome, an admirable blend of balance and harmony, this building is also well-known for its interior décor.

The Panthéon was the first building that visitors arriving in Paris from the provinces or from abroad would see, and from which it was possible to take in the entire city in one complete and exceptional view.
