Grand Châtelet, fortress and prison, headquarters of the Prévôt de Paris
The Grand Châtelet was a fortress and later a prison located on the Île de la Cité in Paris. The structure served as an administrative center and jail complex for centuries before being demolished in 1802.
The Châtelet stood as a fortification from the 11th century onward at this strategic location. Over time it transformed into a prison and administrative building until it was demolished during Paris's urban redesign under Napoleon.
The building no longer exists, but the site on the Île de la Cité can be visited and is easily accessible by public transport. The location provides context for understanding the area's past.
The Châtelet was notorious as one of Paris's darkest prisons, where thousands were held in terrible conditions. Its demolition marked a turning point in the city's modernization and reflected a shift in justice practices.
