Fort du Bourcet, Military fortification in Corenc, France

Fort du Bourcet is a military fortification situated on a hilltop between 415 and 478 meters (1,360 and 1,570 feet) in elevation near Grenoble. From this position, it commands views over the Isère Valley and controls approach routes to the city.

Construction took place between 1875 and 1879 as part of a defensive belt around Grenoble designed to protect against invasion. It was built during a period when France sought to strengthen its eastern borders.

The name honors Lieutenant General Pierre Joseph de Bourcet and his military expertise, chosen by the War Minister in 1887. The fort reflects how the region valued strategic defense and military innovation during that era.

The fort is a private, inhabited property, so the grounds and the restored T-shaped barracks are not open to visitors; the site is seen from the outside. The lower Batteries Basses lie at 415 m and the upper parts at 478 m, reached by paths on the slope. The artillery platforms and the annex battery on the right are overgrown with vegetation.

The barracks' right wing held two adjoining magazines: one segmental-vaulted store for 816,480 cartridges, and a longer barrel-vaulted one for 115,600 kg of black powder, a large quantity for sixteen rampart guns and four mortars. The technical sheet calls it "fort de Bourcet", suggesting the contracted "du" came later.
