The Conciergerie is the main vestibule of the old City Palace or the Palace of the Cité, which was the residence and seat of French royal power from the 10th to the 14th century and which stretched over the site of the Palais de Justice in Paris. Currently, the building extends over the Clock Dock, on the Ile de la Cité, in the 1st arrondissement of Paris. It was converted into a state prison in 1392, after the abandonment of the palace by Charles V and his successors.
The prison occupied the ground floor of the building, bordering the Clock Dock and the two towers; the upper floor was reserved for Parliament. The prison of the Conciergerie was considered like the anteater of the death, during the time of the Terror (French Revolution). Few of them were free. Queen Marie-Antoinette was imprisoned in the Conciergerie in 1793, leaving from there to die in the guillotine.
This monument is managed by the Center of National Monuments, which was awarded as a donation by a decree of April 2, 2008.
