In 1978, a Las Vegas businessman built a bomb shelter for him and his wife to live in in case of Soviet attack.

Now, the estate, made up of two underground houses and an above-ground house with a garage and an acre of land, is listed for sale at $1.7 million. Amenities include a putting green, 360-degree mural, and an underground yard surrounding the place on all sides.
