History of the monument
Louis XV promised a new church to Saint Geneviève and commissioned Jacques-Germain Soufflot. Completed on the eve of the Revolution, it became a Panthéon for major figures in 1791, then alternated between religious and civic use during the nineteenth century. The Republic gradually fixed its memorial role.
How to read the architecture
Soufflot combined a classical portico, Greek-cross plan, light Gothic-inspired structure and triple dome. Nineteenth-century murals, Foucault’s pendulum and the crypt add scientific and republican narratives to the former church. Dome reinforcements also reveal the limits of structural ambition.
Plans, archives and documents
Soufflot’s plans, the Sainte-Geneviève vow, 1791 decree, Foucault’s 1851 experiment and decisions for funerals and pantheonisation document the changing meaning. Read not only crypt inscriptions but who was admitted, when and by which political decision.
The most coherent route
Read portico and dome from Place du Panthéon, trace the four arms and pendulum in the nave, select the murals, then descend to the crypt. Treat panorama access as a separate option when open. Pair with Saint-Étienne-du-Mont, Luxembourg Gardens and the Latin Quarter.
Photography without losing the visit
Begin with a broad view that places the monument on its urban axis, then select two architectural or decorative details. Respect interior restrictions, worship and residents. A useful photograph also records scale, material and the relationship to the surrounding district.
Hours, tickets and access
Hours, security, free or paid access and temporary closures vary with ceremonies, weather, works and season. Check the official source below that morning, buy only from authorised ticketing and allow time for controls.
What to notice before leaving
Return to the façade or starting viewpoint after the interior: chronology, materials and symbols will now read more clearly. Use the related sites below to build a local route rather than crossing Paris between timed reservations.
