Conspiracy Theories
Denver International Airport (DEN), often referred to as DIA, is the subject of numerous conspiracy theories. One of the most pervasive legends is that the airport was built by a secret society, such as the Freemasons, the Illuminati, or the New World Order, with ties to Nazism. The dedication marker at the airport's south entrance features a Freemason symbol and credits an organisation called the New World Airport Commission for building it, despite no evidence of such a group existing. The airport's runway configuration has also been said to resemble a swastika when viewed from above, and various symbols and markings have been interpreted as codes from secret societies or an unknown extraterrestrial language.
The airport's artwork has also fuelled conspiracy theories. Two murals by Leo Tanguma, "Children of the World Dream of Peace" and "In Peace and Harmony with Nature", have been interpreted as containing New World Order imagery and foretelling doomsday scenarios and biological warfare. Similarly, Alex Sweetman's photographic series, "Art Chronicles", includes a photo of dead sunflowers, which some believe hints at an apocalyptic message. The airport also features two gargoyles, "Notre Denver", which historically were added to buildings to protect against evil spirits, and a sculpture, "Blucifer", with demon eyes, which killed its artist during construction.
The large network of underground tunnels and the long-defunct automated baggage system have also sparked theories. Some believe the tunnels contain underground bunkers, hiding lizard people or alien life forms, serving as a safe place for the world's elite during the apocalypse. Others speculate that the tunnels lead to the North American Aerospace Defense Command (NORAD) located about 90 miles south of the airport. The airport's high construction costs, delays, and excessive land area have also led to suspicions of hidden agendas.
Denver International Airport has leaned into these conspiracy theories, hosting exhibitions and events celebrating the most notable theories.

Public Art
Denver International Airport (DIA) has a public art programme financed by a mandatory 1% capital improvement budget, resulting in a significant number of artworks installed throughout the airport. The artwork includes sculptures, murals, photos, sound art, and paintings.
One of the sculptures at the airport is a bronze statue of Denver native Jack Swigert, who flew on Apollo 13 as Command Module Pilot and was elected to the House of Representatives in 1982 but died of cancer before he was sworn in. The statue, dressed in an A7L pressure suit and posed holding a gold-plated helmet, is located in Concourse B and is a duplicate of a statue placed at the United States Capitol in 1997. It was created by Loveland, Colorado artist George Lundeen, who is also the sculptor of "The Aviator", a monumental bronze sculpture of Elrey Borge Jeppesen, for whom the terminal is named.
Denver International Airport also features four murals by the Chicano artist Leo Tanguma: "Children of the World Dream of Peace" and "In Peace and Harmony with Nature", which some believe contain alleged New World Order imagery as proof of the airport's links to a fascist secret society. The murals depict various macabre doomsday scenarios and allusions to biological warfare, but they were actually created to encourage world peace and a healthy relationship with the natural environment. However, they are currently in storage until construction on the Great Hall is completed in the summer of 2028.
Another artwork that has sparked interest is part of Alex Sweetman's "Art Chronicles", a photographic series documenting the construction of the airport. While many of the photo murals capture serene scenes, one photo of a field of dead, browning sunflowers has an unsettling feel. This has led some to speculate that it contains a hidden message about the apocalypse or secret societies.
Adding to the airport's intrigue are two small gargoyles, titled "Notre Denver", atop columns in the east and west baggage claim areas. Historically, gargoyles were added to buildings to protect those inside from evil spirits, and these gargoyles serve the same symbolic purpose. They have become a part of the airport's marketing campaigns, featuring in images with hashtags like #DENFILES, urging viewers to "Learn the truth at DENFiles.com".

History
Denver International Airport (DEN), often referred to as DIA by locals, is an international airport serving metropolitan Denver, Colorado, and the greater Front Range Urban Corridor. It is the largest airport in the Western Hemisphere by land area, covering 33,531 acres (52.4 sq mi; 135.7 km2). The airport is located 25 miles (40 km) northeast of downtown Denver and is closer to the City of Aurora than central Denver.
The history of Denver International Airport dates back to the transfer of land from Adams County to Denver in 1989, increasing the city's size by 50%. The airport replaced the former Stapleton International Airport, which was located much closer to downtown Denver. The construction of DEN sparked numerous conspiracy theories, including rumours that it was built by a secret society, such as the Freemasons, the Illuminati, or the New World Order. These theories were fuelled by various symbols and artworks throughout the airport, such as a time capsule to be opened in 2094, strange markings on walls, and murals with apocalyptic themes.
The airport officially opened for operations in 1995, but it faced significant delays and cost overruns during its construction, leading to speculation about its high cost and prolonged construction time. Over the years, DEN has continued to undergo expansions and renovations to meet the growing needs of travellers and partners. In 2015, a political campaign was launched by Mayor Michael Hancock to expand commercial development at the airport, which was previously prohibited by an intergovernmental agreement. The approval of these changes led to the start of a major interior renovation and reconfiguration of the Jeppesen Terminal in 2018.
Denver International Airport has also experienced several significant milestones in recent years. In 2016, Aer Lingus initiated the first nonstop service between Dublin and DEN, and Turkish Airlines introduced nonstop service between Istanbul and DEN. In 2021, the airport encountered a mechanical failure of its train system, prompting the exploration of supplementary transportation options. In 2025, DEN welcomed the Airbus A380 for regular commercial service, with daily flights to and from Munich International Airport operated by Lufthansa.
The airport boasts an extensive array of shops, restaurants, and amenities to cater to travellers' needs and preferences. It also features a diverse collection of artworks through Denver's public art program, including sculptures, murals, photographs, sound art, and paintings. The artwork showcases both local artists and themes that celebrate peace and environmental harmony. The airport is served by various transportation options, including the A Line commuter rail service to Denver Union Station, bus services, limos, and ride-sharing apps.
