The FT3 combat shelter was built in 1906 on the right bank of the Meuse River as part of the Verdun fortress system, designed to house 100 infantry soldiers. During the Battle of Verdun in 1916, it was converted into a command post (PC118) and changed hands multiple times between French and German forces. The shelter was heavily damaged by French artillery when occupied by German troops, particularly on its vulnerable masonry facade facing Verdun, rendering it unusable.
