Panthéon
The Foucault Pendulum is still there, swinging its slow, hypnotic arc beneath the dome — a replica of the 1851 demonstration that proved, publicly and without argument, that the Earth rotates. It's a good thing to stand under for a moment before you descend into the crypt, where Voltaire and Rousseau lie a few metres apart, Marie Curie has her own alcove, and Victor Hugo's name is carved into stone as though the Republic still can't quite believe it got him.
The Panthéon started life as a church dedicated to Sainte-Geneviève, patron saint of Paris, and ended up as France's secular temple to its own idea of greatness. The tension between those two identities — sacred architecture, secular purpose — gives the building a particular gravity that no amount of tourist traffic quite dissipates.
💛 What travellers fall for
People who return tend to do it for the crypt rather than the nave. Go down early, before tour groups arrive, and take time with the individual tombs — Jean Moulin, Louis Braille, Simone Veil. The dome panorama (April to October, €3.50 extra, around 200 steps) earns its keep on a clear morning with the Sorbonne spread out below.

Louis XV laid the first stone on 6 September 1764, commissioning architect Jacques-Germain Soufflot to build a new Church of Sainte-Geneviève on a site that had held a church of that name for centuries. Soufflot died in 1780 before seeing it finished; Jean-Baptiste Rondelet and Maximilien Brébion brought the work to completion in 1790.
The Revolution changed everything. In 1791 the National Assembly converted the building into a mausoleum for France's great figures, and Voltaire became the first major interment, carried through Paris by an estimated 100,000 mourners. The building oscillated between church and secular monument under Napoleon and Napoleon III before Victor Hugo's state funeral in 1885 settled the question permanently. Marie Curie arrived in 1995 as the first woman interred on merit; Simone Veil in 2018; Josephine Baker in 2021.
