An air raid shelter is an underground shelter from bombing. During the last war the sirens would go off to tell people the German bombers were coming and they would all grab their gas masks and the children and rush to the nearest air raid shelter. This might be a home made one in the garden or one made by the council in the local park or an underground railway station or, in the case of Stockport near Manchester, caves dug out of the rock under the town.
