History
The mountains above Le Lavoir were the focus of an Italian invasion attempt during the Italian invasion of France in 1940. On June 20, Le Lavoir and Ouvrage Sapey fired on Italian forces in the vicinity of the advance post of La Roue, right on the border. The next day the Italian Superga Division infiltrated the area around Ouvrage Pas du Roc. Le Lavoir continued to fire on Italian forces through the day. On the 24th, Le Lavoir fired on Italian troops on the surface of Pas-du-Roc. An explosion in an 81mm mortar injured two of Lavoir's gunners. The armistice of June 25th put an end to action. Altogether, Le Lavoir fired 3818 shots, mostly on 24 June, the most of any ouvrage in the Marienne region.

After the 1940 armistice, Italian forces occupied the Alpine ouvrages and disarmed them. In August 1943, southern France was occupied by the German 19th Army, which took over many of the Alpine positions that had been occupied by the Italians until Italy's withdrawal from the war in September 1943.

In 1944, Le Lavoir was recaptured relatively easily on 13 September, along with the other strongpoints around Modane. The Maurienne positions had suffered little damage during the war and by the end of 1944 were partly repaired and placed into service. Immediately after the war, the Maurienne region was regarded as an area of medium priority for restoration and reuse by the military. By the 1950s the positions in the Southeast of France were restored and operational again. However, by 1960, with France's acquisition of nuclear weapons, the cost and effectiveness of the Maginot system was called into question. Between 1964 and 1971 nearly all of the Maginot fortifications were deactivated.
