Officially opened on February 28, 1995, the Denver International Airport is the largest international airport in the United States, and the second largest international airport in the world. But with its grand size comes a grand theory of its true nature and function.
There are several conspiracy theories relating to the airport's design and construction. Murals painted in the baggage claim area have been claimed to contain themes referring to future military oppression and a one-world government.
In the mid-1990s, Philip Schneider gave lectures about highly secretive government information concerning "deep underground military bases" that were constructed by the United States government, and said that one of these bases exists about two miles underneath the Denver International Airport. Author Alex Christopher claimed to have worked in the tunnels under the airport, and described what appeared to be vast holding areas for prisoners, strange nausea-inducing electromagnetic forces, and caverns big enough to drive trucks through, presumably to be filled with helpless political prisoners.
Conspiracists have pointed to unusual words cut into the floor as being Satanic, Masonic, or just some impenetrable secret code of the New World Order. There is a dedication marker in the airport inscribed with the square and compasses of the Freemasons, along with listing the involvement of the two Grand Lodges of Freemasonry in Colorado, and mounted over a time capsule sealed during the dedication of the airport.
The Freemasons participated in laying the “capstone” (the last, finishing stone) of the airport project. Conspiracists claim that this is a futuristic “keypad” with some unknown purpose. Theorists also note the capstones' engraved inclusion of an organization called the 'New World Airport Commission,' which is believed to denote the facilities' direct association with the fascist New World Order power structure.
