Denver International Airport is a hotspot for wild conspiracy theories. People believe it’s a secret New World Order base, thanks to its weird Freemason plaque and underground tunnels. Some say it’s home to lizard people or even a portal to hell. The creepy murals? Supposedly predicting mass extinction. And don’t forget Blucifer, the demon-eyed blue horse that killed its creator. Whether it’s all a cover-up or just bad design choices, DIA remains one of the strangest airports in the world.
