A Las Vegas local describes the Underground Mansion, a 16,000-square-foot Cold War-era fallout shelter built by Jerry Henderson. The mansion, located 26 feet below an ordinary home, features unique amenities like an underground pool, a retro kitchen, and murals of Henderson's properties. Currently used as an event venue and production location, the site hopes to obtain historical status. Frankie Lewis, the historical caretaker, shares insights into the mansion's history, construction, and Henderson's vision. The Underground Mansion's goal is to preserve Henderson's legacy and offer community services. The venue will be included in the new travel guide "111 Places in Las Vegas You Must Not Miss" later this year.
