Air-raid shelter

An air raid shelter is a place where people can go to stay safe from bombs during a war. It's like a big underground cave with thick walls made of concrete, brick, or metal so that the bombs won't be able to break through and hurt anyone inside. Inside the air raid shelter, there may be beds or benches for people to sit on, and supplies like food and first aid kits in case they have to stay in the shelter for a long time.
