What does Morrison shelter look like?

A Morrison shelter is a type of air raid shelter designed for use during World War II. It typically consists of a rectangular structure made of steel and reinforced concrete, with a flat roof that can double as a surface for sitting or sleeping. The interior is equipped with wooden benches for seating, and the design allows for ventilation while providing protection from bomb blasts. It was intended for use in backyards or gardens, accommodating several people at once.
