Located to the west of Ploegsteert, on the right hand side on the way out of the town, on the Rue de Romarin.
This concrete shelter is marked on trench maps as being next to a light railway, it was one of three marked on the map at that location.
A typical British style of concrete over elephant iron lining and has a door at each end and these entrances had additional side walls for protection however, these have been knocked over.
The shelter was probably used to store ammunition and stores for the artillery batteries located in this area.
