Expiatory chapel to Marie Antoinette

She was held here, separated from her family and watched 24/7 for the last 2 or so months of her life (there were a bunch of royalist plans to break her out, but they all failed). After the Restoration, Louis XVIII mostly tried to keep all factions happy by officially not looking back at the Terreur and the deaths of the Revolution, but he did commemorate the death of Louis XVI, Marie Antoinette and other royals in various ways. For example, by making January 21 (the anniversary of the death of Louis XVI) a national holiday.

This chapel was not done by the king but by the Minister of Police. It’s much more radical than the relatively mild official memorials, elevating the dead king and queen almost as though they were martyred saints.
