The Fort de Bicêtre is a military structure built between 1841 and 1845 during the reign of Louis-Philippe during a time of tension between France and England, in the Paris suburb of Kremlin-Bicêtre. The fort is part of the Thiers Wall fortifications of Paris, built under a program of defensive works initiated by Adolphe Thiers. The fort served as a prison for those involved in the French coup of 1851.
