Visit the place where Marie Antoinette was imprisoned and also executed during the French Revolution. During all of its existence, it was somehow connected to justice and Judicature.
Nowadays, the lavishly embellished palace houses a museum. Part of the palace is also the Sainte-Chapelle - an imposing 13th-century Gothic chapel.
Free admission.
