context: the French Revolution, executions began again in the city center. On 4 February 1832, the guillotine was moved behind the church of Saint Jacques, just before being moved again, to the Grande Roquette prison, on 29 November 1851. On 6 August 1909, the guillotine was used on the junction of the Boulevard Arago and the Rue de la Santé, behind the La Santé Prison.

The device consists of a tall, upright frame in which a weighted and angled blade is raised to the top and suspended. The condemned person is secured with stocks at the bottom of the frame, positioning the neck directly below the blade. The blade is then released, to quickly fall and forcefully decapitate the victim with a single, clean pass so that the head falls into a basket below. The device is best known for its use in France, in particular during the French </s> the Palais de Justice. A number of problems with that execution (inappropriate behavior by spectators, incorrect assembly of the apparatus, and the fact that it was secretly filmed) caused the French government to order that future executions be conducted in private in the prison courtyard.

The final three guillotinings in France before its abolition were those of child-murderers Christian Ranucci (on 28 July 1976) in Marseille, Jérôme Carrein (on 23 June 1977) in Douai and torturer-murderer Hamida Djandoubi (on 10 September 1977)
