Fort de Tourneville, 19th-century military fort in Le Havre, France.

Fort de Tourneville is a fortification built between 1854 and 1860 on the upper town of Le Havre, 140 metres above sea level at 55 rue du 329e-Regiment-d'Infanterie. Its buildings now hold the municipal archives, the Tetris concert hall and recording studios, opened in September 2013, and an artists' nursery. The Tube, a teaching stage, occupies a former underground ammunition store dating from 1938.

Built between 1854 and 1860, the fort belonged to a defensive system with Fort Sainte-Adresse, Fort Frileuse and Fort des Neiges, which let Le Havre resist Prussian attacks from October 1870 to March 1871. In World War I it quartered the 359th Infantry Regiment; the German army then occupied it in World War II, followed by American troops. Infantry regiments used it as a barracks from 1890 to 1976, and the municipality bought it in 1983.

Building A holds the municipal archives and several learned societies: the Société philatélique havraise, the Centre havrais de recherche historique, the Société havraise d'études diverses, the Groupement généalogique du Havre and the Société normande d'études numismatiques. Building B houses artists in residence under the city's artists' nursery, along with the Akté theatre company and the Atelier de musique du Havre.

The fort stands on the upper town at 140 metres above sea level, at 55 rue du 329e-Regiment-d'Infanterie. Buildings A and B hold the municipal archives, artists' studios and cultural associations, while the Tetris concert hall opened in September 2013 on the west side. The Tube, a former underground munitions store, serves as a teaching stage on the east side.

The Tube, a performance stage for rehearsal, creation, training and broadcasting, occupies a former underground ammunition bunker sealed since 1938, on the fort's east side. The Tetris concert hall and recording studios opened in the fort's western enclosure in September 2013.
