This all comes from an article at the Daily Mail, where you can see many more photos. Seems that not only do the Scientologists have an underground vault behind a substantial building in remote New Mexico, but they also have a massive geoglyph that will guide people to it post-apocalypse / alien invasion – and a landing strip.

While no one knows the definite meaning of the pair of overlapping circles, each with a diamond in them, it is believed to have been trademarked by the Church of Technology, a branch of Scientology.

The aerial pictures taken from a helicopter show the house-like structure that covers the entrance to the vault.

Green and beige, the house is built against a flat, stone buttress that blends into the mountain itself.

Down a paved path is a mile-long landing strip, water storage units as well as several RV trailers. The entire complex of buildings and temporary structures sits atop 50-60 acres nestled in the heart of the New Mexico desert 20 miles west of the nearest town of Las Vegas.

During a recent flyover, the compound appeared uninhabited, except for a solitary dog walking the grounds. 

Tim Gallagos, ex-police chief of the Las Vegas, New Mexico, Sheriff’s Department, was given a tour of the vault by church officials in the late 1990s.

He is believed to be the only non-Scientologist to have ever visited the site.

He told MailOnline that within the stone walls are several machines for copying the works of Hubbard.

He explained: ‘They were transferring writings, speeches and videos. This vault is like a giant time capsule and they told me all the scriptures are being kept there.’

In his book The Church of Fear – Inside the Weird World of Scientology, he reports how he was told the vault ‘houses the lectures of church founder L Ron Hubbard on gold discs locked in titanium caskets sealed with argon. The cathedral is H-bomb proof, protected by three 5,000lb stainless steel airlocks.’

He adds: ‘Experts say the weird signs on top of the mountain will guide Clears, [high-ranking Scientologists] returning from space to find Hubbard’s works after a nuclear Armageddon wipes out humanity.’
