The History of La Conciergerie: Palace, Prison, Memorial
Seven centuries on the Île de la Cité — from the medieval seat of French kings to the Revolution's most feared prison, and the monument it is today.
Few buildings in Paris carry as many lives as La Conciergerie. It began as the Palais de la Cité, the medieval royal palace of the kings of France; it became a courthouse and the Revolution's most feared prison; and it is now a national monument on the UNESCO-listed Banks of the Seine. This concierge guide traces that story plainly, from the first kings on the island to the visitor experience you walk through today. We don't run the monument - we are an independent skip-the-line ticket service - but we help thousands of visitors understand what they're seeing before they arrive.
The medieval royal palace
The story begins on the Île de la Cité, the island in the Seine that was the cradle of Paris. From around the year 1000, the early French kings established their main residence here, on the site of an older Roman fortification, and over the following centuries the Palais de la Cité grew into the principal seat of royal power in France. The kings of the late 13th and early 14th centuries, above all Philip the Fair, raised the great halls and riverfront towers whose silhouette still defines the building today.
This was a working palace of government as much as a home: a place of councils, courts and a vast household. The grandest survival of that era is the Salle des Gens d'Armes, the Hall of the Men-at-Arms, built in the early 14th century and regarded as the largest surviving medieval hall in Europe. Below it, the kitchens were built to feed the palace's enormous staff. Together they give a vivid sense of the scale on which the medieval French monarchy operated from this island.
From palace to prison: the kings move out
The turning point came in the 1360s. After a period of unrest in Paris, King Charles V moved the royal residence away from the Île de la Cité to the Louvre and other palaces on the Right Bank. The old Palais de la Cité was not abandoned, however; it kept its role as the seat of royal administration and justice, home to the Parlement of Paris and the law courts. The very name 'Conciergerie' comes from the concierge, the royal officer left in charge of the palace after the king's departure.
With the courts came the prison. From the late 14th century onward, parts of the former palace were given over to holding cells, and over the following centuries the Conciergerie became one of the principal prisons of Paris. The Tour de l'Horloge on the riverfront, meanwhile, had since 1370 carried the first public clock in Paris - a reminder that even as the palace changed function, it remained a fixture of Parisian life, marking the hours over the Seine for everyone to see.
The Revolution and the Terror
The Conciergerie's most infamous era came during the French Revolution. From 1793 it served as the prison of the Revolutionary Tribunal, the court that tried those accused of crimes against the Revolution. Prisoners were held here in the days or hours before their trial and, very often, their execution - which earned the building its grim nickname as the antechamber of the guillotine. More than 2,700 prisoners passed through during this period, with around two-thirds of those tried condemned to death.
The roll of those imprisoned here reads like a history of the Revolution itself. Marie-Antoinette spent her final 44 days in a cell here in 1793. The revolutionaries Georges Danton and Camille Desmoulins were held here before their executions, and in the summer of 1794 so, at the very end of the Terror, was Maximilien Robespierre himself. The same corridors thus carried both the Revolution's victims and the architects of its bloodiest phase - a symmetry that gives the prison much of its lasting power.
From prison to national monument
The Conciergerie continued to serve as a prison long after the Terror, through the 19th century and into the 20th, before it was finally decommissioned and opened to the public as a historic monument. After the original cell of Marie-Antoinette was lost, a commemorative chapel had already been raised on its site in 1815 under the restored monarchy, and that act of remembrance set the tone for how the building would later be presented - as a place of memory as much as architecture.
Today the Conciergerie is a national monument and museum, and part of the UNESCO World Heritage inscription covering the Banks of the Seine in Paris. Visitors move from the medieval halls to the revolutionary prison spaces, with the included HistoPad tablet rebuilding both eras in augmented reality. It is a rare building that lets you stand inside the long arc of French history - royal power, revolutionary violence and modern remembrance - all within the same set of walls on a single island.
Frequently asked
What was the Conciergerie originally?
It was the Palais de la Cité, the medieval royal palace of the kings of France on the Île de la Cité. From around the year 1000 the early kings made it their main residence, and it grew into the principal seat of royal power, with great halls and towers built in the 13th and 14th centuries.
When did it become a prison?
After King Charles V moved the royal residence to the Louvre in the 1360s, the old palace kept its role as a courthouse and administrative seat, and from the late 14th century parts of it were turned into a prison. It became one of the main prisons of Paris over the following centuries.
Why is it called the Conciergerie?
The name comes from the 'concierge', the royal officer left in charge of the palace after the king moved out. The officer's role gave the whole building its enduring name.
How many prisoners were held here during the Revolution?
More than 2,700 prisoners passed through the Conciergerie during the Terror, when it served as the prison of the Revolutionary Tribunal. Around two-thirds of those tried were condemned to death, which is why it was called the antechamber of the guillotine.
Which famous people were imprisoned at the Conciergerie?
Marie-Antoinette spent her final 44 days here in 1793. The revolutionaries Danton and Camille Desmoulins were held here, and at the end of the Terror in 1794 so was Robespierre himself - meaning the prison held both the Revolution's victims and its leaders.
