Called "the most interesting home in the world" by Robin Leach, the Hammargren Home is in Las Vegas. Lonnie Hammargren, a retired brain surgeon, former Nevada Lieutenant Governor and Honorary Consul to Belize, owns this house, which is actually three homes that form one large compound. The first of the three is a planetarium and celestial observatory, the second is a replica of the "House of the Governor" at a Mayan site at Uxmal, and the third is inspired by Frank Lloyd Wright's designs in Hollywood.
