The stone fortifications of Fort de Bois l'Abbé

Nestled at an altitude of 384 meters, Fort de Bois l'Abbé, also known as Fort Poniatowski, is part of the fortifications of Épinal, France. Constructed between 1883 and 1885 in the Séré de Rivières system, it is located 1,200 meters east of its larger neighbor, the Fort d'Uxegney. The stone construction provides an example of an un-modified position, and the fort remained relatively unchanged prior to World War I. Its initial arsenal encompassed four 120mm guns and two 90mm guns, with supplementary smaller arms.

In 1915, it was upgraded with 75mm anti-aircraft guns, although the larger guns had been removed. The fort lost strategic importance as its views were obstructed by the Bois de Souche, prompting the construction of smaller positions within the woods. These were not completed at the time of mobilization in 1914. Between 1900 and 1906, 'queue de cochon' or "pig's tail" infantry shelters were installed around the fort. By 1913-14, the fort was equipped with electricity from the local power grid. It functioned as a central bakery, supplying bread to Fort d'Uxegney and Fort de la Grande Haye.

During World War I, the German forces did not reach the vicinity of Épinal, sparing Fort de Bois l'Abbé from action. After the aerial bombardment of Épinal, concrete platforms were placed on the surface of the fort for 75mm anti-aircraft guns, but the guns were never installed. During the interval between World War I and World War II, the fort remained military property, serving as an ammunition depot. During World War II, it was utilized by the Germans to house their occupying forces and for ammunition storage.

Post World War II, the French army maintained an ammunition depot at Fort de Bois l'Abbé until 1960. After 1960, the fort was used by private tenants before being restored by the Association pour la Restauration du Fort d'Uxegney et de la Place d'Épinal (ARFUPE) beginning in 1995. The fort may be visited on special occasions.
