What different types of shelters were there in World War 2?

Answer 1

Underground tube stations were often used as Public shelters and places such as church halls and other public buildings were used. The latter two didn't give much protection from falling bombs but feeding and toilet facilities were available to the people. If individual families had a garden, they were supplied with an 'Anderson' shelter for home assembly. This was basically sheets of curved corrugated iron which would be half buried in a back yard. Firstly a hole would be dug and the sheets assembled in the hole. The earth that had been excavated to make the hole would then be back filled on top of the 'ark' giving a degree of protection unless it was a direct hit.
