Origin and history

The former stopping house of Fontainebleau, built in 1845 by the departmental architect of Seine-et-Marne, illustrates the Pennsylvanian prison model promoted under the Third Republic. Inspired by convents, his nave plan and his panoptic system (central rotonde for total surveillance) reflect the doctrine of solitary confinement, defended by Alexis de Tocqueville. With its 45 cells of 9 m2 spread over two floors, the prison was designed for chapel-oriented detention, symbolizing a moral and religious approach to reintegration.

As early as the 1880s, the prison, considered too small and dilapidated, was criticized for its inadaptation to prison needs. During the Second World War, German authorities used it to incarcerate resistance fighters: 39 detainees, who disappeared in 1944, were found buried near Arbonne-la-Forêt after the Liberation. Closed in 1990, the prison was classified as a historic monument in 1996 before sheltering, from 1995 to 2010, the National Prison Museum, now transferred to Agen.

The building, representative of 19th-century prison architecture, combines a 5 metre high wall with a centralized monitoring system. After its decommissioning, its collections (more than 10,000 documents over three centuries of prison history) are kept by the National School of Prison Administration. In 2016, the site was sold to a developer for conversion to housing, despite its protected status.

The museum project, which began in the Universal Exhibition of 1889, was implemented through national collections conducted between 1967 and 1982. Directed by conservative Catherine Prade (named in 1991), the museum exhibited items seized in prison (escape tools, historical documents) before closing for lack of means. A new prison history museum was opened in 2027.

Architects Mangeon and Trelat, authors of the plans according to the circular of 1841, also designed the prisons of Meaux and Coulommiers. The site, located 1 rue du Sergent-Perrier, remains a major testimony of the 19th century prison reforms, between repression and ideal rehabilitation.
