The Paris parish of Saint-Gervais-Saint-Protais after a bomb attack in the First World War. During the Good Friday service on March 29, 1918, the bullet of a German so-called "Paris Gun", from the enormous range of about 130 kilometers, hit the roof of the church building, causing the collapse of the vault. There were 88 dead and 68 wounded. For almost five months, the French capital was fired by 800 shells of up to three of these "Paris guns". However, because of their low precision, they were ineffective in military respect and only led to damages in the civilian population.
