Tunnel 88

Tunnel 88 refers to an alleged underground facility located within the Cheyenne Mountain Complex in Colorado Springs, Colorado. While the Cheyenne Mountain Complex is a well-known hardened military installation primarily used by NORAD (North American Aerospace Defense Command) and US Space Command, the specific existence and purpose of "Tunnel 88" remains largely unconfirmed and is often associated with conspiracy theories.

According to unsubstantiated claims, Tunnel 88 is a deeper, more secretive level of the complex, potentially used for advanced research, clandestine operations, or as a secure refuge during a large-scale disaster. Some theories suggest it could house extraterrestrial technologies or serve as a command center for a shadow government.

Official sources from NORAD and the U.S. military do not acknowledge the existence of Tunnel 88. The details surrounding the alleged facility are primarily found on online forums, blogs, and speculative fiction, lacking credible documentation or corroboration. The numbering convention "88" itself has no known significance within official Cheyenne Mountain Complex schematics or published operational information. Therefore, the existence and activities allegedly associated with Tunnel 88 should be regarded as speculative.
