New York City has begun removing the vestiges of its Cold War history by taking down nuclear fallout shelter signs on schools and other buildings.

The city's government said the 1960s relics no longer present up-to-date information about where to find shelter during a nuclear missile or bomb attack. Many of the shelters are no longer functional.

The nuclear shelters that were set up during the Democratic administration of former President John F. Kennedy do not exist, despite the fading yellow radiation signs that hang above many of the public schools in the Big Apple, Reuters reported Wednesday.

The shelters were designated during the time of the Cuban missile crisis, when it was discovered that the former Soviet Union had been setting up nuclear missile sites in Cuba, threatening the United States.

Most of the shelters, which used to receive federal funding to stock with food and supplies, have been closed for decades. People seeking shelter at the sites in 2017 would find only locked doors.

Michael Aciman, spokesman for the city's Department of Education, confirmed that the fallout shelters in the city’s school system are not active.

The goal is to finish removing the signs from the school walls by Jan. 1, Aciman said.
