Fort du Lomont

Fort du Lomont is a military fortification situated at 803 meters elevation on the Lomont mountain chain, featuring thick masonry walls and an outer perimeter spanning roughly 1.5 kilometers. The structure spreads across portions of three communes in eastern France.

This fortification was built between 1875 and 1878 by the Adrien Hallier company as part of the Séré de Rivières defensive system. A gunpowder magazine was excavated into the rock in 1889 to support the artillery operations at the site.

The fort functioned as a communication relay point between mountain fortifications, with signal systems connecting it to neighboring positions across the high ground.

The fort sits atop a mountain ridge and requires hiking to reach it, with the path and terrain varying in difficulty depending on the approach route. Visitors should bring appropriate footwear and weather gear due to exposure at the elevated location.

The northern section contains a substantial artillery battery that dominates the ridgeline and reveals the fort's strategic positioning. The powder magazine carved directly into the bedrock demonstrates the specialized engineering techniques used in late 19th-century military construction.
