Pantheón

This is where many famous French people are buried, mostly intellectuals like Voltaire, Rousseau, Marat, Victor Hugo, Émile Zola, Jean Moulin, Marie Curie, Louis Braille. Looking at all their crypts gets kind of boring, but it is interesting place to visit. One really cool thing about the building is that it houses an experimental device built by Léon Foucault to demonstrate the earth's rotation and it still works!
