Centre hospitalier Théophile Roussel - Saint Germain Boucles de Seine

At the time of its creation, the establishment was intended to replace the Parisian Peitite Roquette prison, which housed young offenders. In 1902, it was transformed into an 'école de préservation' (a juvenile detention centre for girls), the first of its kind in France, and was named after Théophile Roussel.

In 1974, it became a public mental health institute specialising in juvenile and adult psychiatry.

Guided tours of this historic place are often available on Journées Européenes du Patrimoine (European Heritage Days), sometimes supported by exhibitions and films.
