Made it back to Paris from Versailles at around half-past six and headed to the Panthéon, unfortunately, it was already closed when we arrived. The Panthéon is a church and mausoleum, a Neoclassical structure originally built by Louis XV for St. Genevieve. Pierre & Marie Curie, Voltaire, Alexandre Dumas, and many other French personalities are resting here. It was modeled after the Pantheon in Rome.
With nothing else planned for the evening, we just sat and people watched. The surrounding buildings in front of Place du Pantheon, I believe, are parts of La Sorbonne.
Dinner at the flat: store-bought caprese and a quiche from a neighborhood patisserie.
