Atlas Survival Shelters still produces the Anderson Shelter today. It was created in 1939 in England to protect the civilian population from aerial bombardment. This simple shelter measured 6 feet high, 4.5 feet wide and 6.5 feet long. They were buried 4 feet deep into the soil and then covered with a minimum of 15 inches of soil above the roof. Over 2.1 million were installed during WWII and are credited for saving hundreds of thousands of lives in England.
