Fort des Adelphes

Fort des Adelphes is a five-sided military fortification located near Deyvillers featuring defensive ditches and artillery positions. The structure includes observation posts integrated into its ramparts designed for territorial defense purposes.

The fort was built between 1883 and 1885 as part of the Séré de Rivières defense system created to protect against threats from the east. Significant modernization works took place between 1907 and 1914 to upgrade its capabilities.

The fort represents French military engineering of the late 19th century, demonstrating the nation's response to territorial defense after previous conflicts.

The site is not open to public visits as it serves as a training facility for military personnel. You can view the exterior from a distance but cannot enter the grounds.

From 1990 to 2014, the fort operated as an electronic warfare station for the French Air Force. This later role demonstrates how the old fortification was adapted for modern military technology.
