In 1961, President John F. Kennedy sent out a letter to American citizens warning them about the threat of nuclear war. His solution: fallout shelters.
"We owe that kind of insurance to our families and to our country," his letter read. "The time to start is now. In the coming months, I hope to let every citizen know what steps he can take without delay to protect his family in case of attack. I know you would not want to do less."
Congress allocated $169 million to find locations in public and private buildings that would protect communities from nuclear attacks. One of these shelters was built under Oyster-Adams school in Washington, DC. After the Cold War, it remained untouched for decades.
In the basement, three steps lead to a green door. Behind the door, you will find the fallout shelter.
