The Anderson shelter was a type of air-raid shelter used in the United Kingdom during World War II. Designed by engineer Sir John Anderson, it was made of corrugated steel and could accommodate up to six people. Families often installed these shelters in their gardens to protect themselves from bombings. The shelter was easy to assemble and cost-effective, making it accessible to many households. It was designed to be partially buried in the ground, providing additional protection. The Anderson shelter became a symbol of civilian resilience during the war, allowing families to feel safer during air raids.
