Overview
Since its opening in 1995, Denver International Airport (DIA) has been the subject of numerous conspiracy theories. Proponents point to its massive budget overruns, unusual artwork (including apocalyptic murals), and a dedication capstone mentioning the "New World Airport Commission"—an organization that does not exist.
Underground Bunkers
A popular theory suggests the airport sits atop a massive underground facility intended as a bunker for the global elite during a cataclysmic event. Airport officials have stated the tunnels were part of a failed automated baggage system.
