The First Construction Dates from Roman Times

On Ile de la Cité there’s a castellum or palatium since the 4th century AD. The Palatium occupied an area of ​​around one hectare. This space housed the Praetorian Tribunal and was temporarily the home of the two Roman Emperors Julian and Valentinian.

During the following centuries, the Franc Kings had a traveling court, and they stayed in Palais de la Cité during their trips to Paris. It was King Huges Capet, the first Capetian king, who in the 10th century established the Curia Regis (the Royal Council) and various departments of its administration in Palais de la Cité.

The Conciergerie Owes its Splendid Gothic Architecture to King Philippe Le Bel

Conciergerie Building

It is mainly to King Philippe Le Bel (1268-1314) that the building owes its Gothic architecture and turrets. At the time, the palace was considered one of the most beautiful in Europe!

King Philip commissioned the Grande Salle the largest Gothic civil hall in Europe – where the king gave justice and hosted sumptuous receptions and banquets.

Conciergerie Meaning

Years later, King Charles V (1338-1380) decided to move his court outside the ramparts of Philippe Auguste in the current Marais. The Palace Guard, which had become an honorary and occasional residence, was entrusted to the Concierge, a high figure in the kingdom. The Concierge was appointed by the king to ensure order, the police, and register the prisoners.

The Conciergerie in Paris owes its name to this Concierge of the Palace, and the name was extended to all the buildings guarded by the Concierge.

The Conciergerie is France’s Oldest Prison

By the end of the 14th century, King Charles VI (1368-1422) converted the Conciergerie into a state prison, where many prisoners awaited trial and execution. In the Conciergerie prison, the richest had their own cell with a bench, while the less fortunate were crammed on the floor.

The Conciergerie Hosted the Revolutionary Tribunal

During the French Revolution, the Conciergerie was the scene of the sessions of the Revolutionary Tribunal, during which nearly three thousand people were sentenced to death.

One of the most famous prisoners was Queen Marie-Antoinette, who spent her last days before being beheaded in one of these cells. For some time, visitors to the Conciergerie could see Queen Marie-Antoinette’s cell, the ‘décor’ of which had been reconstructed.

During the renovation of the museum, this reconstruction was removed to make way for a chapel.

The Conciergerie is Next to One of the Most Visited Places in Paris

Sainte Chapelle Paris

Tour César – The Caesar tower. Built on Roman foundations, it is so named in memory of the presence of Romans in Paris.

Tour d’Argent – The silver Tower. This tower kept the royal treasure.  

Tour Bonbec – Good Word Tower. This tower was the place where the ‘question’ (torture) was practiced, which made the tortured confess (bonbec or good beak = good word).

The Conciergerie Clock is the Oldest in Paris

The 47m Tour de l’Horloge is decorated by the oldest clock in Paris. Working since 1371, the Conciergerie clock is stunning, and it had the purpose of helping Parisians regulate their activities during the day and night.

A Latin inscription is found below the clock: ‘MACHINA QUAE BIS SEX TAM JUSTE DIVIDIT HORAS, JUSTITIAM SERVARE MONET LEGESQUE TUERI’ which is translated in English by ‘This mechanism which divides time into perfectly equal twelve hours helps you to protect justice and defend the law’.

A Peek Inside the Conciergerie, Paris

People visiting the Conciergerie Paris will be amazed by the impressive 14th-century rooms and halls built in Gothic Style


Commissioned by King Philippe le Bel, this is the biggest Gothic hall still existing in Europe. Its dimensions are impressive: 68,80m x 27,4m x 8,5m.

Located on the ground floor, the level for the King’s staff and service, it was used as a refectory by the King’s numerous servants and men at arms (up to 2,000 people). Four huge fireplaces heated the hall, and the vaults originally had windows that illuminated the space.

Don’t miss the capital depicturing the history of Héloïse and Abélard.


This also impressive hall was used by the Royal Guard. Later it was used as the anti-chamber to the Grande Salle, where the King gave justice.

When the King left the Palace, the Concierge installed here the dungeons for the prisoners without resources.


Commissioned by King Jean Le Bon, these kitchens were used to prepare the food for the King’s staff.
