Did you know that in the 1950s, the US government carved out a secret underground city that could survive a nuclear attack? It’s called an "underground Pentagon", and very much like Area 51, it is one of the government's most classified projects.

This military complex and nuclear bunker is located near Blue Ridge Summit, Pennsylvania, 768 feet below the ground. It’s protected by 23.5 ft thick 30-ton doors built on top of springs to survive the shock from a blast. Raven Rock has five buildings with 15 floors big enough to live and work. The base has everything it needs to keep running, like a cafeteria, a barbershop, water generators, and even a medical center.

SubTropolis

Below Kansas City, Missouri, lies the world's largest underground business complex. SubTropolis is a structure located inside a mine north of the Missouri River. It was carved out of limestone some 135 to 185 feet underground and covers a total of 55 million square feet.

Kansas City Chiefs founder Lamar Hunt built this subterranean city in the 1960s. It has offices, storage space, and even factories. Over 1,600 people work here every day, largely because SubTropolis remains cool all year, making it an ideal location for businesses. Fun fact: some of Hollywood’s most beloved masterpieces are kept here, including the original film reels of Gone with the Wind and The Wizard of Oz.

Underground Atlanta

Underground Atlanta is a historic spot in downtown Atlanta, Georgia. It was built in the late 1800s, right after the Civil War, as a commercial district centered around the railroad. In the 1920s, viaducts were built and the streets were raised, creating a second level of streets, buildings, and shops.

During Prohibition, the abandoned underground space served as the best spot for speakeasies and juke joints. For decades, people forgot about the hidden city, but in the 1960s, it was brought back to life as a fun place for music bars and nightlife.

Under America’s most populous city, there's a whole hidden world. For example, beneath Little Italy and the Public Library, there are secret vaults. Beyond the subway millions of people use daily, there is City Hall station, opened in 1904 and closed in 1945. It's a hidden gem with stained glass and mosaics that you can still visit by staying on the 6 train past the last stop.

But that’s not all! There are trading tunnels in SoHo and old cattle tunnels in the Meatpacking District. Also, in 1897, there were mail tubes built around the city to send letters between post offices that operated until the 1950s. Some of these underground spaces go as deep as 800 feet!

A large part of the land in the northern hemisphere is Permafrost, so it makes sense that there is a research facility specially built to study it. The Permafrost Tunnel in Alaska is the best place to learn about frozen soil that's over 40,000 years old.

The long tunnel was dug from 1963 to 1969 to study how to build and mine in frozen environments. Inside the facility, scientists study ice, ancient plants, and even bones from animals like mammoths. The tunnel shows different layers of earth, uncovering frozen ground from different time periods that help scientists anticipate what might happen as the world gets warmer.

The Greenbrier Bunker in White Sulphur Springs, West Virginia, is a secret underground facility beneath a luxury hotel that has hosted numerous US presidents and famous guests. It was built during the Cold War to protect the US Congress in the event of a nuclear attack. The bunker was designed to house all 535 members of Congress and their staff for a long time.

This classified underground facility remained a secret until 1992, when a Washington Post article exposed it. Today, visitors can take tours to see special rooms, blast doors, and decontamination areas.

Would you attend a concert underground? If you travel to Tennessee is totally possible! The Caverns, formerly known as Bluegrass Underground, is a very cool spot in Grundy County, Tennessee. Lying deep in a cave 333 feet underground, this concert venue with natural acoustics is the perfect place for live music.

People come from all over to hear a variety of performances, especially Bluegrass music. The Caverns can accommodate up to 1,200 people standing up and are equipped with state-of-the-art sound and lights. The cave's cool and quiet atmosphere makes the experience extra special!

Beneath the neighborhood of Crystal City, near Washington, DC, lies a network of shops, restaurants, and offices. It opened in 1976 and was designed to feel like an old shopping village with cobblestone streets and antique glass windows.

The underground space covers 150,000 square feet and connects several buildings. It's a popular spot for office workers and visitors, especially when the weather is bad. Unfortunately, in 2024, the shops closed, ending their retail era. Yet, the underground walkways and connections to the Metro remain open for pedestrians.

In the 1920s, during Prohibition, people had to find ingenious ways around the restrictions on selling and consuming alcohol. That's why they built about 11 miles of underground tunnels right under Los Angeles.

Many of these subterranean sites are now closed, but you can still find a few hidden entrances around the city. You can even go on a tour to explore the tunnels and learn about their secret history.

After a big fire in 1904 destroyed Havre’s business district in Montana, many shops moved underground. They used the old steam tunnels to stay safe from fires and bad weather. For years, the tunnels were busy with people and stores, such as saloons, drugstores, laundromats, and even a brothel. But today it is completely silent.

Fortunately, you can still visit what is left of this hidden city to see old shops and learn how people stayed safe and worked over 100 years ago. It's like going back in time!

Cheyenne Mountain Complex

One of the safest places in the world is right here in America, more specifically in El Paso County, Colorado. Hidden inside a mountain, Cheyenne Mountain Complex was built in the 1960s to protect the US military from nuclear attacks.

The bunker stands under 2,000 feet of solid Granite, making it super strong and safe. It was once the command center for NORAD (North American Aerospace Defense Command). The complex has blast doors that weigh 25 tons each and can withstand a nuclear blast. It also has its own power, water, and food supply. People could survive there for months!

A Sicilian immigrant called Baldassare Forestiere spent 40 years digging and building a series of subterranean structures by hand in Fresno, California. Inspired by Roman catacombs and old wine cellars, he created around 65 rooms, tunnels, and courtyards to escape the hot summer sun.

The Gardens have fruit trees, grapevines, fishponds, and even a chapel. Some of the trees are more than 90 years old! Today, Forestiere Underground Gardens is a Historical Landmark you can visit if you want to discover a true underground paradise.

A meatpacker from Troy sparks a nickname

In 1812, while the country was at war with Britain again, soldiers stationed near Troy, New York, needed to eat. A local businessman named Samuel Wilson, who ran a meatpacking company with his brother Ebenezer along the Hudson River, won a contract to supply barrels of beef and pork to the army.

Wilson stamped every barrel "U.S." for United States, but around town he was already known by a friendlier name, Uncle Sam, for being an honest and generous employer to the many workers who passed through his docks. Soldiers saw the initials, heard the nickname, and started joking that their rations came courtesy of "Uncle Sam" himself. What started as a joke stuck, and local newspapers quickly picked it up, marking the first step in Uncle Sam’s story.

2

A patchwork figure before the patriotic suit

Before Uncle Sam wore his familiar star-spangled coat, he looked more like any other fisherman.

The earliest known drawing of him appeared in the New York Lantern in 1852 , decades after Samuel Wilson first earned the nickname back in Troy. In that cartoon, he had no top hat, no red and white stripes, nothing close to what you would recognize today. Early illustrators dressed him in rustic, everyday clothes, sometimes patchwork, because he was meant to represent the common American, not a polished symbol of government sitting in an office. It took years of cartoonists experimenting, borrowing bits from other figures and dropping others, before Uncle Sam’s look settled into anything close to consistent.

3

The Civil War gives him his iconic aesthetic

During the Civil War, Uncle Sam needed to do more than represent the country. He needed to rally it. Editorial cartoonists of the era, most famously Thomas Nast at Harper’s Weekly , reworked him into someone sharper and more commanding , trading the rustic patchwork look for a tall, lean man with a top hat and striped trousers.

Nast used Uncle Sam to speak for the Union cause and to argue for keeping the country unified, at a time when families followed the war through newspaper cartoons the way we now follow headlines on our phones. This version of Uncle Sam, dignified rather than folksy, laid the groundwork for the figure who would later stare down at millions of Americans from recruitment posters, decades before that poster was ever drawn.

4

Uncle Sam becomes a tool of political satire

By the turn of the 20th century, Uncle Sam had developed a new side: he could make a political argument without saying a word.

As the United States expanded overseas after the Spanish-American War, cartoonists used his body, clothes, and size to debate what that expansion meant. Around 1900, in J.S. Pughe’s cartoon "Declined with thanks," an oversized Uncle Sam gets measured for an ever bigger suit, a visual joke about the country’s growing territorial expansion. The joke was visual, but the issue was serious. Uncle Sam had become a flexible political weapon, useful both to supporters and critics of American power. The character could literally grow as the nation grew, making him ideal for newspaper satire.

5

A British general points the way first

Here’s the twist most people don’t know about: That famous pointing finger, the one every American associated with Uncle Sam, was not originally American at all.

In 1914, as Britain entered World War I, illustrator Alfred Leete created a recruitment poster showing Lord Kitchener, Britain’s Secretary of State for War, pointing directly at the viewer above the words: "Britons: Join Your Country’s Army." The poster ran on magazine covers and street corners across the country and became one of the most talked-about images of the war’s early days. A few years later, on the other side of the Atlantic, an American artist would study that same commanding pose and realize it was exactly what his own country needed to put on paper.

6

An artist paints himself into history

That American artist was James Montgomery Flagg, a well-known illustrator commissioned by the Committee for Public Information to create a recruitment poster for WWI in 1917.

The plan was simple: echo the Kitchener pose with an American face. There was just one problem: the model scheduled to sit for the painting never showed up that day. Rather than waste the afternoon, Flagg propped up a mirror in his studio and used his own reflection, adding a goatee and white hair to age himself into the role of Uncle Sam. The result, "I Want You for U.S. Army," turned out to be the defining image of Uncle Sam for generations, all because one artist got impatient and decided not to wait around for someone else to show up.

7

A single poster printed over four million times

Numbers rarely tell a full story, but this one comes close. Between 1917 and 1918, Flagg’s Uncle Sam poster was printed more than four million times, plastered across train stations, storefronts, and town squares nationwide, often right next to enlistment tables.

It pushed Americans to sign up for service, to buy Liberty Bonds, and to see the war as something that involved them personally, not just the soldiers overseas. Few pieces of American graphic design have ever reached that scale of distribution, and fewer still have stayed recognizable a century later. If you have ever seen a Halloween costume, a magazine cover, or a protest sign featuring that pointing finger, you have already seen Flagg's poster still at work.

8

Uncle Sam trades his rifle for a baseball bat

Not every wartime appearance of Uncle Sam involved a battlefield. Illustrators found plenty of other uses for his familiar face between 1917 and 1918, some of them surprisingly playful.

J.C. Leyendecker drew him swinging a baseball bat under the slogan "Get in the Game," nudging Americans toward the war effort through a sport nearly everyone already loved on weekend afternoons. Flagg himself created a gentler image of Uncle Sam with his arm around a horse, part of a campaign asking Americans to support the care of military animals overseas. These lighter, unexpected adaptations remind us that propaganda during that era was not only about urgency; it also leaned on familiarity and warmth to make its point stick.

9

Pearl Harbor brings the same face back

When Japan attacked Pearl Harbor in December 1941, the country needed a rallying image fast, and rather than starting from scratch, officials reached for something already proven.

Flagg’s 1917 interpretation was dusted off and reprinted by the millions once again, this time for WWII enlistment drives and home front civil defense campaigns. The same stern face that had once urged an earlier generation to sign up was now doing the job all over again for their sons, appearing on posters in recruiting offices, factories, and post offices nationwide. By the 1940s, he was more than a wartime recruiting figure. He was a shorthand symbol for the federal government and the country itself.

10

From wartime symbol to modern canvas

Uncle Sam did not retire once the World Wars ended. In the decades since, he has become something closer to a blank canvas that each generation paints over with its own concerns.

During the Vietnam era, protest artists twisted his familiar pose into pointed criticism of the very government he once represented so simply, using his own famous finger to accuse instead of recruit. Political cartoonists continue to reach for him today, whether the topic is an election, a policy debate, or a national controversy, counting on readers to instantly recognize who he stands for. Few American symbols have proven so adaptable, stretched and reshaped again and again across more than two centuries, yet somehow always recognizable the moment that pointing finger appears.
