English City of Coventry Sustains Devastating Bombing from German Luftwaffe

There were public shelters in most towns, but many people built Anderson shelters in their gardens so that they had protection if they were unable to get to the public shelter. Anderson shelters were made out of corrugated iron and were very strong. A hole was dug in the garden, then the shelter was placed in the hole and it was covered with earth. An air-raid siren warned people when a raid was about to begin.
