The Church of Scientology built a huge vault into a a mountainside in New Mexico, marked by huge aerial signpost of their symbol.

According to the Washington Post:

"Buried deep in these New Mexico hills in steel-lined tunnels, said to be able to survive a nuclear blast, is what Scientology considers the future of mankind," ABC's Tom Jarriel said in his report. "Seen here for the first time, thousands of metal records, stored in heat-resistant titanium boxes and playable on a solar-powered turntable, all containing the beliefs of Scientology's founder, L. Ron Hubbard."
