With your prepaid admission voucher in hand, make your way to the Île de la Cité, home to the Conciergerie on the banks of the Seine. Your skip-the-line access ticket gives you the right to proceed directly inside the former Paris Seat of Justice, past the waiting crowds.
Learn about the transformation of the Conciergerie throughout history, from Royal Palace to Justice of the French monarch to Revolutionary Tribunal. See the cell where Marie-Antoinette was imprisoned, among other famous prisoners during this time.
Just a few steps away is the 13th-century Sainte-Chapelle, a French Gothic chapel that has recently been restored. Your ticket also gives you skip-the-line access to this monument, which features more than 1,000 scenes from the Old and New Testaments.
Both monuments are yours to explore independently after your express entry, and you can visit them in any order you choose.
