Denver Fun Facts
1. Denver’s Elevation is Exactly One Mile High
Denver isn’t called the Mile High City for nothing! The city sits at exactly 5,280 feet (or one mile) above sea level, giving it a unique geographical distinction. You can even find a marker on the steps of the Colorado State Capitol denoting the exact one-mile elevation. Because of this altitude, Denver’s air is thinner, which means less oxygen and lower humidity, making for clearer skies and a dry climate that can surprise visitors.
One of the most fascinating Denver fun facts related to its elevation is how it affects everything from cooking to sports. Water boils at a lower temperature in Denver, which means baking requires adjustments for altitude. Athletes often train in the city to build endurance, as the lower oxygen levels make workouts more challenging. This advantage has even helped Denver’s sports teams, as visiting teams often struggle with the high altitude.
2. The Cheeseburger Was Trademarked in Denver
Did you know that Denver is home to the cheeseburger? In 1935, Louis Ballast, the owner of the Humpty Dumpty Drive-In, was awarded the first-ever trademark for the term “cheeseburger.” While the actual invention of adding cheese to a hamburger is widely debated, Denver takes pride in being the city that officially claimed it first. Today, you can find a commemorative plaque at the site where Ballast’s restaurant once stood, celebrating this delicious contribution to American cuisine.
This is one of the tastiest Denver fun facts, as the city remains a haven for burger lovers. From classic diner-style burgers to gourmet creations using Colorado-raised beef, Denver’s food scene continues to embrace its cheeseburger legacy. If you’re a foodie, exploring the city’s burger joints is a must-do experience when visiting.
3. The First Permanent Structure in Denver Was a Saloon
Denver was founded during the Pike’s Peak Gold Rush in 1858, and the very first permanent structure built in the city was not a government building or a home—it was a saloon! This reflects the city’s Wild West roots, as prospectors, gamblers, and fortune seekers flocked to the area in hopes of striking it rich. With a booming mining industry, Denver quickly became a hotspot for entertainment, attracting cowboys, outlaws, and pioneers alike.
This historical tidbit is one of the most exciting Denver fun facts, as the city still maintains a strong connection to its Old West past. Today, you can visit historic saloons like the Buckhorn Exchange, Denver’s oldest restaurant, which opened in 1893 and still serves up classic Western dishes. The city’s vibrant nightlife and brewery scene are a modern extension of its original frontier spirit.
4. The Denver Airport Conspiracy Theories
Denver International Airport (DIA) is not just one of the busiest airports in the U.S.—it’s also one of the most mysterious. Since its opening in 1995, DIA has been the subject of countless conspiracy theories, ranging from secret underground bunkers to hidden Illuminati symbols. The airport’s unusual design, strange murals, and the ominous 32-foot-tall “Blue Mustang” statue with glowing red eyes have fueled speculation for decades.
Among the strangest Denver fun facts is how the airport embraces these theories. DIA has leaned into the mystery by putting up tongue-in-cheek signs and even dedicating sections of its website to addressing the rumors. Whether you believe in the conspiracies or not, DIA’s bizarre history makes it one of the most talked-about airports in the world.
5. The Capitol Building’s Dome is Covered in Real Gold
The Colorado State Capitol is one of Denver’s most striking landmarks, and its dome is covered in real gold leaf. This feature was added in 1908 to commemorate Colorado’s gold rush history, paying tribute to the miners who helped shape the state’s economy. The building itself is made from Colorado white granite, making it not only historically significant but also architecturally stunning.
One of the most dazzling Denver fun facts about the Capitol is that visitors can tour the building and even step onto the observation deck beneath the golden dome. From there, you get breathtaking panoramic views of the Rocky Mountains and downtown Denver, making it a must-visit spot in the city.

Sitting in one of these seats gives you a unique perspective—both literally and figuratively—on the game.
One of the coolest Denver fun facts about Coors Field is how the high altitude affects baseball. Because of the thinner air, baseballs travel farther, making Denver one of the best cities for home runs. The stadium even stores baseballs in a humidor to counteract the altitude’s impact on the game!
