First a palace then Marie Antoinette prison

Conciergerie is a former royal palace and prison in Paris, France, located on the west of the Île de la Cité. It is part of the larger complex known as the Palais de Justice, which is still used for judicial purposes. Hundreds of prisoners during the French Revolution were taken from La Conciergerie to be executed on the guillotine at a number of locations around Paris.
By 1391, the palace had been converted to a prison for both common and political criminals. Wealthy prisoners were given the best accommodations in the former palace while petty thieves were made to sleep in dark, rodent-infested rooms where they often succumbed to diseases such as the plague.
