What You'll Learn

Lizard people and aliens
Denver International Airport has been the subject of numerous conspiracy theories since its opening in the mid-1990s. One of the most prominent theories revolves around the existence of "lizard people" and aliens, allegedly living in underground tunnels beneath the airport.
The theory of lizard people and aliens at Denver Airport stems from several factors, including the airport's unique features, construction delays, and rumours of secret societies. The airport has a large network of underground tunnels, a train system connecting concourses, and a long-defunct automated baggage system. Some believe that these tunnels serve as underground bunkers, possibly built by or hiding lizard people and alien lifeforms. The idea of bunkers is further fuelled by the existence of unusual murals by artist Leo Tanguma, which depict man-made environmental destruction and genocide, as well as the airport's dedication marker, which mentions a group called the ""New World Airport Commission," a name similar to the alleged secret society, "New World Order."
Adding to the intrigue, the airport has embraced and even capitalised on these conspiracy theories. They have featured advertisements and posters that playfully allude to the theories, such as signs with giant lizards in construction gear, apologising for noise and attributing it to "really big drills to get to the underworld." The airport has also hosted events like a conspiracy-themed costume party and a screening of "Close Encounters of the Third Kind."
The theories suggest that the lizard people and aliens are connected to secret societies, such as the Freemasons, Illuminati, or the New World Order, who may have built the airport as a safe place for the world's elite during the apocalypse. The airport's massive size, delays, and cost overruns during construction have further fuelled speculation.
While these theories may seem far-fetched, they have persisted and even grown in popularity, with some people taking them very seriously. The airport's playful engagement with these conspiracies has only added to the allure, making Denver International Airport a hotbed of intrigue and fascination for conspiracy theorists and curious travellers alike.

Secret tunnels
One of the most popular conspiracy theories about Denver International Airport is the existence of a network of secret tunnels beneath the airport. These tunnels are rumoured to be full of lizard people, leading to underground bunkers, and connected to a headquarters for the New World Order. The airport's remote location, swastika-shaped runway configuration, and various symbols of Nazism or fascism have further fuelled these theories.
The conspiracy theories surrounding the Denver Airport's secret tunnels first emerged due to the airport's delayed opening, large budget overrun, and mysterious construction. The airport went over budget by $2 billion and opened 16 months behind schedule. Additionally, a multi-million-dollar automated baggage system failed to work as designed, leading to speculations about the true intent and scale of the construction.
Contractors who worked on the airport reported seeing evidence of bunker entrances and unexplained tunnels. The airport's own marketing campaigns have played into these theories, with signs featuring giant lizards dressed in construction gear, jokingly apologizing for the noise and large drills needed to reach the underworld.
Adding to the intrigue, an "alien" drawing was discovered on the walls of the tunnels, and blurry footage of "lizard people" has surfaced on conspiracy websites. Some even speculate that a tunnel connects the airport to NORAD, located nearly 100 miles to the south near Colorado Springs. However, the feasibility of this tunnel is questionable, as it would be highly costly and take a significant amount of time to construct.
The existence of secret tunnels at Denver International Airport remains a popular conspiracy theory, with the airport embracing and even encouraging these theories as a form of publicity.

Cursed horse statue
Denver International Airport, also known as DIA, is the subject of numerous conspiracy theories. One of the most prominent theories revolves around a 32-foot-tall, bright blue statue of a horse with glowing red eyes, nicknamed 'Blucifer' by the locals. The statue, officially named 'Blue Mustang', was created by El Paso-born artist Luis Jiménez and has become a symbol of the airport. However, it is also regarded as a "cursed horse statue" by many conspiracy theorists.
The story behind the creation of the statue adds a layer of intrigue and fuels its reputation as a cursed horse statue. Commissioned in 1993, the sculpture took nearly 13 years to complete. Tragically, in 2006, an accident occurred during the creation process, resulting in a large piece of the statue falling on Jiménez and causing his death. After this incident, the statue was finished by Jiménez's staff, sons, and other professional artists, and it was finally installed at the airport in 2008.
The statue's appearance also contributes to its ominous reputation. With its veiny texture, permanent fighting stance, and neon red eyes that seem to glow like burning coals at night, the horse statue has an intense and unnerving presence. Some have described it as a "veiny horse in a permanent fighting stance," enhancing the sense of unease it evokes.
Adding to the mystery, the Blue Mustang statue has been associated with conspiracy theories about secret societies, such as the Freemasons, the Illuminati, and the New World Order. These theories suggest that these secret societies influenced the construction of the airport and that the horse statue may be a symbolic representation of their power or a harbinger of doom. The airport's remote location, unusual architecture, and high construction cost have further fueled these conspiracy theories.
The Denver International Airport has embraced its reputation for intrigue, often incorporating the conspiracy theories into its marketing campaigns. While some may find these theories entertaining, others take them very seriously, seeking meaning and security in these wild ideas. Regardless of one's beliefs, the Blue Mustang statue, with its troubled history and imposing presence, remains a distinctive feature of the airport, captivating the imaginations of travellers and conspiracy theorists alike.

Freemasons and the New World Order
Denver International Airport has been the subject of numerous conspiracy theories since its opening. One of the most prominent theories suggests that the airport is under the control of the Freemasons, a centuries-old secret society, in collaboration with the New World Order, a group of global elites who seek to dominate international affairs.
The basis for this theory lies in several architectural and artistic features of the airport, as well as certain unusual circumstances surrounding its construction and operation. Firstly, a dedication plaque at the airport's south entrance bears the date March 19, 1994, and contains a time capsule and the symbol of the Freemasons, along with a reference to the enigmatic "New World Airport Commission". The existence of this commission is disputed, leading some to believe that it is linked to the Freemasons and their alleged agenda for a New World Order.
Adding to the intrigue, the airport features a 40-piece public art collection, including murals by artist Leo Tanguma, gargoyle sculptures, and a massive Mustang sculpture with glowing red eyes, which some interpret as apocalyptic or sinister in nature. Conspiracy theorists claim that these artworks contain hidden messages and symbolism related to the New World Order and the Freemasons. The murals, for instance, depict scenes of war and peace between people and nature, which some interpret as foretelling a biowarfare apocalypse that will culminate in the New World Order taking control.
Furthermore, the airport's construction and operational history have fuelled speculation. The airport's construction cost exceeded the initial estimate by $2 billion, and it opened 16 months behind schedule, leading to theories about hidden underground bunkers meant to house the global elite in case of an apocalyptic event. The existence of tunnels and multiple levels underneath the airport, along with reports of "strange markings" and "alien languages," have further intensified these beliefs.
It is important to note that while the Freemasons are a legitimate fraternal organization with historical ties to the airport's dedication, there is no concrete evidence to support their involvement in the airport's ongoing operations or decision-making. Additionally, the theories surrounding the Denver International Airport have been a subject of fascination and entertainment, with the airport itself embracing and poking fun at these conspiracies.

Art and murals
Denver International Airport (DIA) is known for its art and murals, some of which have sparked controversy and fuelled conspiracy theories. The airport features a variety of sculptures, murals and installations that are permanent fixtures.
Among the most famous and controversial artworks at DIA are two murals by local artist Leo Tanguma, titled "In Peace and Harmony with Nature" and "Children of the World Dream of Peace". These were commissioned when the airport was being built in 1994-1995 and are located in the east and west baggage claims outside of the Great Hall. Each mural is divided into two sections, separated by doorways, and explores themes such as environmental destruction, warfare, and peace.
"In Peace and Harmony with Nature" is said to resemble Mexican social realist murals and depicts a horrific scene of environmental destruction, with trees burning, animals in glass cages, and young people fleeing. The second half of the mural shows a diverse group of children and animals coming together around a futuristic plant, representing the rehabilitation of nature.
"Children of the World Dream of Peace" also features contrasting scenes, with the first half showing the tragic impact of war and destruction, and the second half depicting happy children from around the world celebrating world peace.
Tanguma's murals have attracted attention for their apocalyptic and disturbing imagery, with some interpreting them as references to secret societies, future mass extinctions, or the New World Order. However, the artist has stated that his intention was to reflect the beautiful and the wrong in society, exploring themes of peace, multiculturalism, and environmentalism.
Other artworks at DIA include "Notre Denver" by Terry Allen, which features two bronze gargoyles sitting inside suitcases at either end of the baggage claims area; "Mile High and Rising" by Marcus Akinlana, which celebrates the spirit of adventure and triumph of African Americans in Colorado; and "La Memoria de Nuestra Tierra" (Our Land Has Memory) by Baca, which represents the migration of Mexicans during the Mexican Revolution.
