The Panthéon is a building in the Latin Quarter in Paris. It was originally built as a church dedicated to St. Genevieve and to house the reliquary châsse containing her relics but, after many changes, now functions as a secular mausoleum containing the remains of distinguished French citizens.
Here’s the principal level, decorated with paintings on canvas marouflé illustrating the life of Saint Geneviève and the epic story of the beginnings of both Christianity and the monarchy in France.
The Foucault’s pendulum first installed inside Panthéon in 1851 and removed then reinstalled in 1995, this device demonstrated the Earth’s rotation.
Two more photos of Chenonceau castle that I visited last time.
