Notre Dame de Lorette, also known as Ablain St.-Nazaire French Military Cemetery, is the world's largest French military cemetery. It is the name of a ridge, basilica, and French national cemetery northwest of Arras at the village of Ablain-Saint-Nazaire. The high point of the hump-backed ridge stands 165 metres high and - with Vimy Ridge - utterly dominates the otherwise flat Douai plain and the town of Arras.
The ground was strategically important during the First World War and was bitterly contested in a series of long and bloody engagements between the opposing French and German armies. It was the focal point of three battles of Artois (1914-1915). The Battles of Artois were as costly in French lives as the better-known Battle of Verdun. As with numerous other sites across France, Notre Dame de Lorette became a national necropolis, sacred ground containing the graves of French and Colonial fallen, as well as an ossuary, containing the bones of those whose names were not marked.
In total, the cemetery and ossuary hold the remains of more than 40,000 soldiers, as well as the ashes of many concentration camp victims. The basilica and memorial buildings were designed by the architect Louis-Marie Cordonnier and his son Jacques Cordonnier, and built between 1921 and 1927. The first small building was raised in 1727 by the painter Nicolas Florent Guilbert, who had made a successful pilgrimage to Loreto (Italy), to shelter a statue of the Virgin Mary. It was destroyed in 1794, rebuilt in 1816 and transformed in 1880.
Redipuglia is the largest Italian Military Sacrarium. It rises up on the western front of the Monte Sei Busi, which, in the First World War was bitterly fought after because, although it was not very high, from its summit it allowed an ample range of access from the West to the first steps of the Karstic table area.
The monumental staircase on which the remains of one hundred thousand fallen soldiers are lined up and which has at its base the monolith of the Duke of Aosta, who was the commanding officer of the third Brigade, and gives an image of a military grouping in the field of a Great Unity with its Commanding Officer at the front. The mortal remains of 100,187 fallen soldiers lie here, 39,857 of them identified and 60,330 unknown.
