At the end of the 14th century it became a prison. Its history ended up tragically for the French monarchs, since the revolutionary terror reached its most violent peak there; it is in this place that Marie Antoinette and her children were locked up.
Every day of the year the prison can be visited; some of the main French prisoners were locked up there. You may be amazed at its curved cellars, belonging to gothic style, and at its historically and architecturally beautiful interiors.
