Batterie des Roches, Military fortress in Pont-de-Roide-Vermondans, France.

Batterie des Roches is a Séré de Rivières fort on a hilltop at 615 m, its north and west sides protected by a cliff and its east and south sides by two moats overlooked by the ramparts. The site holds the battery entrance, barracks, bakery, powder magazine, an optical post for signalling to Fort du Mont-Bart, a double caponnière and an underground magazine. The entrance wall of light tan stone carries an arched tunnel and a plaque dated 1877.

The fort belongs to the Séré de Rivières fortifications of eastern France and formed part of the Lomont defensive hub, where it was a key piece together with its annex batteries. It watched the Doubs valley, the Vesoul to Saint-Hippolyte road and the plateaus of Écot, Ecurey and Blamont, and blocked any southern bypass of Fort du Mont-Bart. Construction and land cost 954,867 gold francs, and the battery housed 246 men.

The fortress functions as a nature observation site where visitors can witness researchers tracking migrating birds during peak seasons. This dual role connects military heritage with contemporary wildlife studies.

The site is reached on foot from Pont-de-Roide-Vermondans; the fort stands at 615 m on a hilltop ringed by the Crêt des Roches regional nature reserve. Its north and west sides drop along a cliff, while two ditches cut on the east and south are overlooked by the ramparts. The site is now frequented by walkers.

The fort's optical post relayed signals to the Fort du Mont-Bart, one link in the Lomont defensive chain. Its garrison numbered 246 men: 6 officers, 16 non-commissioned officers and 224 soldiers, with a 10-bed infirmary. The site also held a bakery, a powder magazine and a double caponier.
