During World War I many French villages were destroyed, some never to be reconstructed because they were heavily damaged or because the nearby fields contain unexploded munitions, mines, explosives and artillery shells. French WWI soldier Edouard Marius Ivaldi died for France in one of these villages on April 30, 1917. After the war, his father Jean-Joseph searched for the remains of his son and started the grieving process. In 1919 he placed a wood cross on the spot where his son fell in combat in Champagne, eastern France, then in 1924 he placed a plaque with his son's name in the chapel of the Navarin Ossuary. Almost 100 years later, this place of private memory, its location unknown to visitors, has remained untouched over time.
