Saranac, New York
To the naked eye, this is just a house with killer Adirondack views. But hidden below the surface is a 176-foot-deep missile silo, measuring 52 feet in diameter. In other words: a massive bomb shelter built to withstand a 200-pound-per-square-inch blast.
Certainly not an ordinary mountain getaway, the silo was constructed by the United States Air Force in 1958 and was an active Intercontinental Ballistic Missile launch facility from 1961 until 1965, when it was decomissioned.
See the inside of the silo on the next slide.
