An excellent view of L'Ouvrage d'Ars - June 1955.
It is understood that the L'Ouvrage d'Ars was used as a supply warehouse during the mid 1950s. This appears to be supported with the lumber and other materials that are stored in the area that would eventually serve as an RCAF parking lot when the bunker was renovated and used as the COC.
