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!

Permafrost Tunnel Research Facility

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.

The Caverns

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!

Crystal City Underground

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.

Los Angeles Prohibition Tunnels

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.

Havre Beneath the Streets

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.

Rachel Jackson: A "Bigamy" scandal (1820s)

In 1791, a young Andrew Jackson married Rachel Donelson. Both believed her first husband, Captain Lewis Robards, had successfully finalized their divorce. Apparently, Robards didn’t file the petition, making her marriage to Jackson technically bigamous. Once the divorce went through in 1794, they officially remarried.

During the 1828 presidential campaign, Jackson’s political opponents used this legal mistake against him. They branded Rachel a loose woman and a bigamist in pamphlets scattered across the country. The intense public shaming broke her spirit and deteriorated her health. She suffered a fatal heart attack just days before Jackson’s inauguration, leaving the newly elected president heartbroken and extremely bitter toward his political rivals for the rest of his life.

Grover Cleveland’s illegitimate child (1884)

Decades later, another personal bombshell rocked another presidential race. Republican opponents revealed that Democratic nominee Grover Cleveland, a bachelor praised for his integrity, had fathered a child out of wedlock with a widow called Maria Halpin ten years before.

Republicans paraded through the streets chanting, "Ma, Ma, where’s my Pa?" Instead of denying the affair or trying to bury it, Cleveland instructed his campaign managers to do something radical: "Tell the truth." He admitted to supporting the child financially. His honesty caught his opponents off guard and won over voters who were tired of such dirty political tactics.

3

The Crédit Mobilier scandal (1872)

This particular scandal stands as one of the most shameless corporate schemes of the Gilded Age. Stockholders of the Union Pacific Railroad formed a fraudulent construction company called Crédit Mobilier of America . Then, they hired themselves to build the transcontinental railroad at inflated prices, pocketing tens of millions of dollars in federal subsidies.

To prevent Congress from investigating their profit margins, Congressman Oakes Ames distributed discounted shares of the company’s stock to influential politicians, including Vice President Schuyler Colfax. When the press exposed the story in 1872, the revelation that lawmakers were bribing themselves tarnished the legacy of the Ulysses S. Grant administration.

4

The Whiskey Ring scandal (1875)

A few years later, another financial disaster hit the Grant administration. The Whiskey Ring was a widespread conspiracy involving distillers, distributors, and internal federal tax officials who stole millions of dollars in liquor taxes.

Using a complex web of bribes and falsified records, the ring defrauded the U.S. Treasury. The scandal reached the inner circle of power when President Grant’s own private secretary, Orville Babcock, was indicted as a ringleader. Grant provided a deposition in his secretary’s defense. While this saved Babcock from prison, it permanently damaged the president’s reputation.

5

The Teapot Dome scandal (1920s)

Until Watergate occurred, Teapot Dome was synonymous with political corruption. During the administration of Warren G. Harding, Secretary of the Interior Albert Fall took control of valuable federal oil reserves located at Teapot Dome, Wyoming, and Elk Hills, California.

Instead of opening these fields up for competitive bidding among energy companies, Fall secretly leased the drilling rights to private oil tycoons in exchange for more than $400,000 in bribes.

6

The Chappaquiddick incident (1969)

By the mid-20th century, the nature of political scandals shifted. Secrets began to involve personal crisis and tragic losses.

In July 1969, Senator Edward "Ted" Kennedy drove his car off a narrow wooden bridge on Chappaquiddick Island, Massachusetts. The vehicle overturned into a tidal pond, trapping and drowning his passenger, 28-year-old campaign worker Mary Jo Kopechne. Kennedy managed to escape but failed to report the fatal accident to the police for ten hours. Although he eventually pleaded guilty to leaving the scene of an accident, his delayed reaction ended his lifelong presidential ambitions.

7

The Pentagon Papers (1971)

In 1971, military analyst Daniel Ellsberg felt the moral obligation to leak a top-secret 7,000-page Department of Defense study detailing U.S. political and military involvement in Vietnam from 1945 to 1967.

Published by The New York Times , the papers exposed a disturbing truth: successive administrations had systematically lied to both Congress and the American public. The documents proved that the government had expanded the war and increased troop counts while knowing that the conflict was unwinnable. The Supreme Court eventually rejected the government’s attempts to block the leaks, making a victory for freedom of the press.

8

The Watergate scandal (1972–1974)

This is, probably, the ultimate American political scandal. In June 1972, five men were arrested breaking into the Democratic National Committee headquarters at the Watergate complex in Washington, D.C.

The break in itself was minor compared to the illegal cover-up orchestrated by President Richard Nixon and his collaborators. From paying hush money to instructing the CIA to block the FBI’s investigation, Nixon’s complicity was exposed via his own secret White House taping system. Facing impeachment and conviction by the Senate, Nixon became the first and only U.S. president to resign from office.

9

The "Keating Five" (Late 1980s)

During the Savings and Loan crisis of the late 1980s, five U.S. Senators—John McCain, Alan Cranston, Dennis DeConcini, John Glenn, and Donald Riegle—came under intense scrutiny.

The group was accused of intervening with federal banking regulators on behalf of Charles Keating, the chairman of Lincoln Savings and Loan, who had contributed to their political campaigns. Lincoln eventually collapsed, costing American taxpayers over $3 billion. Although the Senate Ethics Committee ultimately cleared the senators of corruption, they were publicly condemned.

10

The Bill Clinton–Monica Lewinsky affair (1998)

The 20th century ended with a scandal that blended personal infidelity with a constitutional crisis. In 1998, news broke that President Bill Clinton had an intimate relationship with a 21-year-old White House intern called Monica Lewinsky.

The affair turned into a legal battle when Clinton denied the relationship under oath during an unrelated sexual harassment lawsuit. The investigation led to Clinton’s impeachment by the House of Representatives on charges of perjury and obstruction of justice. The Senate ultimately acquitted him, yet he couldn’t bypass the media circus.

He was of French descent

While we think of Paul Revere as an early American icon, his roots lay across the Atlantic. His father, Apollos Rivoire, was a French Huguenot (a member of the French Reformed Church) who fled religious persecution and immigrated to Boston as a teenager.

To fit in his new home, Apollos Americanized the family name to "Revere". Paul was born in late 1734 or early 1735, the son of Apollos and a Boston local called Deborah Hichborn. Apollos was so interested in blending in that he never taught his children to speak and read French. In fact, a young Paul Revere even fought against the French as part of the colonial forces during the French and Indian War.

2

He was an accomplished artisan

Before he was a revolutionary, Revere was a master craftsman. He learned the art of silversmithing from his father and quickly gained a reputation as an accomplished artisan. He designed seals, coats of arms, plate engravings, and silver teapots.

Revere also used his engraving skills to create sharp political cartoons that mocked the British. His most famous artistic work was a sensationalized engraving of the 1770 Boston Massacre. It wasn’t entirely historically accurate, but it spread through the colonies, stirring up the anti-British sentiment that laid the groundwork for the Revolution.

3

He worked as an amateur dentist

When silversmithing work ran slow, Revere picked up a side hustle: dentistry. He started cleaning teeth and crafting dental prosthetics out of animal teeth and walrus ivory for the people of Boston.

This amateur dental career actually led to a major moment in American history. In 1775, Revere’s close friend, Dr. Joseph Warren, was killed at the Battle of Bunker Hill and buried in an unmarked mass grave by British soldiers. A year later, when the bodies were exhumed, the remains were unrecognizable. Yet, Revere was able to identify Warren’s body by recognizing the specific ivory tooth and custom wire bridge he had personally crafted for his friend. It’s widely considered one of the earliest documented cases of forensic dentistry in the United States.

4

He played a key role in early intelligence efforts

Long before the CIA existed, Paul Revere was working as a pioneer of organized American espionage. As a member of the Sons of Liberty, Revere wanted to track British movements closely. In 1774, he helped form a spy group known as "the mechanics" or the "Liberty Boys".

These men were Bostonian blacksmiths, artisans, and laborers who used their ordinary routines to watch British troops, listening for rumors of upcoming military actions. The spies would gather at the city’s historic Green Dragon Tavern to trade secrets and map out British movements.

5

Longfellow's inaccurate poem

If your knowledge of Revere comes from Henry Wadsworth Longfellow’s famous 1861 poem, "Paul Revere's Ride," you’ve been given a romanticized version of history. Longfellow wrote the poem nearly a century later, on the brink of the American Civil War, to stir up national pride.

In reality, Revere wasn’t a lone rider. The night of April 18, 1775, Revere set out with two other main horsemen: William Dawes and Dr. Samuel Prescott. As they triggered local alarms, dozens of other riders joined the effort. By midnight, more than 40 people were racing across the country, spreading the word. Furthermore, Revere never actually made it to his final destination of Concord. He was captured and briefly detained by a British patrol.

6

He didn’t even own a horse for his midnight ride

It’s hard to imagine the midnight ride without Revere’s faithful steed, but the truth is, Revere didn’t even own a horse when the fateful night arrived. Because he had to be quietly rowed across the Charles River, bringing a horse from Boston was out of the question.

Once he reached Charlestown, he had to find a ride. He ended up borrowing a horse from a sympathetic local merchant called John Larkin. Legend has it that this borrowed mare was named "Brown Beauty". Sadly, after Revere was captured later that night, the soldiers confiscated the horse, and she was never seen again.

7

He didn’t actually say THAT

"The British are coming!" is one of the most famous quotes in American history, but Revere never said it. The countryside was crawling with British soldiers, so his mission had to be very quiet. Yelling at the top of his lungs would have landed him in military prison before he even left town. Instead, he went door to door delivering the warning quietly to specific patriots.

Also, the phrase wouldn’t have made sense to the colonists. At the moment in 1775, the colonists still considered themselves British citizens. Instead, historical accounts indicate that Revere used the phrase, "The Regulars are coming out!" "Regulars" was the standard colonial term for the standing British army troops.

8

His military record wasn't outstanding

Although Revere was a phenomenal community organizer and courier, his transition into traditional military leadership didn’t go smoothly. During the war, he served as a major and later a lieutenant colonel in the Massachusetts State Artillery. His military career hit a disastrous low point in the summer of 1779 during the Penobscot Expedition in modern-day Maine.

The mission was a total failure for the Americans. In the aftermath, Revere was accused of cowardice, laziness, and disobedience. He faced a court-martial and spent several years fighting to clear his name. He was ultimately acquitted of all charges in 1782, but the incident permanently tarnished his dreams of military glory.

9

Fatherhood came early… and often

If you think managing a household today is stressful, consider Paul Revere’s domestic life: he fathered an astonishing 16 children.

He had his first eight children with his first wife, Sarah Orne. Following her death in 1773, he remarried a woman called Rachel Walker, with whom he had another eight children. They crammed this huge family into a small townhouse at 19 North Square in downtown Boston. Amazingly for the 18th century, 11 of his 16 children survived to adulthood.

10

Revere Copper Products, Inc. is still in operation

After the Revolution ended, Revere left politics and went back to industry with some success. He opened a hardware store, a foundry, and the first rolling copper mill in the United States.

In fact, his business supplied the copper used to protect the hull of the USS Constitution. He also cast nearly 1,000 church bells, many of which still ring across New England today. Amazingly, the company he founded, Revere Copper Products, Inc., is still in business. Paul Revere passed away in 1818 at the age of 83, leaving behind a legacy more industrious than a single night’s ride.
