A secret bunker hidden deep within the deserts of New Mexico is reported to be the "alien space cathedral" of the Church of Scientology, according to the author of a new book on Scientology. 

The site is marked by a large symbol etched onto the desert floor: two diamonds surrounded by a pair of overlapping circles, according to the British newspaper The Sun. A private airstrip, built to serve the controversial church's leaders, is within walking distance of the symbol.

The entire complex is located near Mesa Huerfanita, N.M., roughly two-hour's drive from Santa Fe, N.M., and three hours north of Roswell, N.M., site of numerous purported UFO sightings, according to The Sun.

The Sun report, penned by BBC journalist (and author) and Scientology debunker John Sweeney, claims the church designed the underground site to withstand a nuclear holocaust. Hidden within the complex's vaults are titanium caskets that hold gold disks inscribed with the original texts of Scientology founder L. Ron Hubbard, according to the Daily Mail. (MORE AT YAHOO.COM)
