Caserne de la Cité

The Caserne de la Cité (lit.'City Barracks') is a public building on the Île de la Cité, Paris, France, on a prominent site facing Notre-Dame. It has been the seat of the Paris Police Prefecture since 1871.

Originally a barracks and headquarters erected in the 1860s for the National Guard (French: garde nationale de Paris), it has also hosted units of the Republican Guard (garde républicaine) from 1871 to 1929 and the headquarters of the Paris Fire Brigade (brigade des sapeurs-pompiers de Paris, a military unit that reports to the Police Prefect) from 1867 to 1938.

The building played a prominent role during the liberation of Paris in August 1944, when it served as a bastion and command center of the Resistance and the site of the formal surrender of German forces.
