Among its many record-breaking achievements, America has one lesser-known record that also deserves attention.

Our country is home to the largest office building in the world. Want to know which one? The world's largest office building by floor area is the United States Department of Defense, also known as the Pentagon.

Ok, but how big is it? Located in Arlington, Virginia, and famous not only for its size but also for its distinctive five-sided design, the building has a total floor area of approximately 6.5 million square feet.

People in New York

We all know that New York City is packed with people. In fact, it's the most populous city in our country. But how many live there?

As of 2024, around 8.8 million people call NYC their home. That's a huge number on its own, but it might be even more impressive when you consider that NYC's population surpasses that of 40 US states, including Montana, New Hampshire, and Mississippi, to name a few. In other words, NYC has more residents than each of those 40 states individually.

After all, New York City is famously known as "the city that never sleeps" for a reason!

Many versions of the flag

Image: Chris Hardy

The US flag is one of our most beautiful and beloved symbols and also one of the most recognized worldwide. With its distinctive stripes, stars, and classic red, white, and blue colors, it is an unmistakable icon. But did you know it has undergone several changes over the years?

The US flag has not just had 1, 2, or 3 versions; in fact, there have been 27 official versions! Each of these versions served an important purpose, reflecting some key changes throughout our history. For example, whenever a new state joined the Union, an additional star was added. This is how we arrived at the 50 white stars you see in the upper left corner of our beautiful flag. The current version was made official on July 4, 1960.

No official language

Image: Ben Duchac

While English is the most widely spoken language in the United States, the country does not have an official language at the federal level.

This might surprise some people, given that English is the primary language for most Americans and is used for government and legal purposes.

On the other hand, many other languages are spoken here as well. For instance, Spanish is the second most spoken language, though it is used considerably less than English. And that's not all; Chinese, Filipino, and French also have a notable number of speakers in the US!

The fastest-speaking states

Image: Chris Liverani

We all have that friend who speaks so fast it's hard to keep up, even if you know them well. Would you like to know how fast Americans speak?

Fortunately, there's not just data on the languages we use but also on how quickly we speak in our daily lives. And it turns out that a few states lead the pack in this speed race.

According to the Smithsonian Institution, Oregon, Minnesota, and Massachusetts are the states where residents speak the fastest . So, if you know someone from those states, why not give it a try and see if you can keep up with their speedy conversations?

Most airports in the world

Image: Alex Underwood

Americans seem to love air travel, and there's a good reason for that: the US holds the record for the most airports in the world!

This isn't just a coincidence. The vast size of our territory— yes, we're one of the largest countries in the world—requires fast, safe, and efficient ways to travel to all corners.

With thousands of airports of all kinds spread across the country, it's no wonder that so many movies feature airport scenes or are even filmed inside airplanes, right?

Alaska's price

Image: Joris Beugels

We have the great advantage of having the gorgeous state of Alaska as one of the 50 states. Beyond its natural beauty, it holds another impressive distinction: it's the largest state by area, covering approximately 663,300 square miles.

As you may know, Alaska was purchased in 1867 when US Secretary of State William H. Seward sealed a deal with Russia to acquire the territory. However, what some people may not know is just how affordable it was: the purchase cost $7.2 million, which means we acquired Alaska for about 2 cents per acre! To put it in perspective, adjusted for inflation, that $7.2 million would be equivalent to about $140 million today.

The first national park in the world

Image: Nicolasintravel

The United States is home to some of the most spectacular and diverse national parks in the world. And not only that, but we also have the honor of being the country that established the world's very first national park.

Inaugurated on March 1, 1872, Yellowstone National Park became the Earth's first national park. This event marked a turning point, leading to the creation of many other national parks and protected areas both in America and around the globe.

The incredible Yellowstone spans approximately 3,472 square miles , primarily in Wyoming, with portions extending into Montana and Idaho. Have you had the chance to visit it?

A special feature on Washington National Cathedral

Image: Ryan Arnst

The Washington National Cathedral offers many attractions for visitors, starting with its beautiful Gothic-style architecture. However, it also holds some secrets and fun facts within its walls.

Construction began in 1907 and took 83 years to complete. The wait was well worth it, as the Washington National Cathedral is now the sixth-largest in the world! And here's a fun fact: its famous Space Window features a real piece of moon rock at its center. Amazing!

Additionally, there's also a quirky feature that some visitors overlook: on the Cathedral's façade, there's a gargoyle with the face of none other than Darth Vader! This Star Wars character was added to the building's northwest tower in the 1980s after a children's design competition. A curious touch, isn't it?

Miles of bookshelves

Image: Roman Kraft

The Library of Congress is much more than a beautiful complex of buildings. Located on Capitol Hill in Washington, D.C., this famous landmark was established over 200 years ago in 1800 . Since then, it has preserved and protected countless documents, treaties, and books that reflect and constitute our nation's history.

Adding to our list of world records, the Library of Congress holds the title of the largest library in the world. It boasts an incredible 164 million items, which translates to 838 miles of bookshelves. That's enough to cover the distance from Atlanta, GA, to New York City, NY!

John Adams

Image: Mark Olsen

Middle name: Quincy

Our sixth president, John Quincy Adams, was the son of the second president, John Adams. He was named "Quincy" after his maternal great-grandfather, John Quincy, and later signed his initials as "JQA" to avoid confusion with his father. A strong mind clearly ran in the family.

2

William Harrison

Image: STEPHEN POORE

Middle name: Henry

William Henry Harrison, the ninth president, was named for both his grandfather and uncle. Sadly, his presidency was the shortest in history, just one month after he caught pneumonia giving a long speech in the rain.

3

James Polk

Image: Daniel Weiss

Middle name: Knox

James Knox Polk carried his grandfather’s name with pride. Born in North Carolina in 1795, he expanded the nation’s territory by more than a third during his single term, finally stretching the U.S. from coast to coast. Quite an accomplishment for one presidency.

4

Ulysses Grant

Image: Jake Blucker

Middle name: Ulysses

Fun fact: "Ulysses S. Grant" wasn’t his real name. He was born Hiram Ulysses Grant, but a paperwork mix-up at West Point changed it forever. The "S" came later as a nickname, "US" Grant, something that fit a general far better than "H.U.G." ever could.

5

Rutherford Hayes

Image: Matt Koffel

Middle name: Birchard

Rutherford Birchard Hayes got his middle name from his mother’s maiden name. Born in 1822, he lost his father before birth but grew up to become the 19th president. He’s remembered for restoring faith in the presidency after a rough patch in American politics.

6

Grover Cleveland

Image: Manisha Raghunath

Middle name: Grover

Stephen Grover Cleveland dropped his first name early in life and stuck with Grover. It worked out well for him: he’s the only president in history to serve two nonconsecutive terms, making him both the 22nd and 24th president. That’s a comeback story.

7

William Taft

Image: Jake Blucker

Middle name: Howard

William Howard Taft’s middle name honored his grandmother’s family, the Howards. He remains the only person to ever serve as both U.S. president and Chief Justice of the Supreme Court. That’s two of the toughest jobs in one lifetime.

8

Woodrow Wilson

Image: STEPHEN POORE

Middle name: Woodrow

Born Thomas Woodrow Wilson, he eventually dropped his first name and went by Woodrow instead. It sounded distinguished, and clearly, it worked for him. As our 28th president, he guided the nation through World War I and helped shape modern international relations.

9

Warren Harding

Image: Oz Seyrek

Middle name: Gamaliel

Warren Gamaliel Harding, born in Ohio in 1865, left his mark on American vocabulary by coining the word "normalcy." He wanted life to return to normal after World War I. His middle name, likely biblical, matched his calm, reassuring image.

10

Calvin Coolidge

Image: John Holm

Middle name: Calvin

John Calvin Coolidge, our 30th president, was named for his father but went by his middle name from childhood. Known as "Silent Cal," he led with few words and steady leadership during the Roaring Twenties.

11

Herbert Hoover

Image: Niko Vassios

Middle name: Clark

Herbert Clark Hoover shared his middle name with his father, Jesse Clark Hoover. Born in Iowa in 1874, he was a self-made man long before entering politics. Sadly, his presidency became synonymous with the Great Depression, but he remained known for his work ethic and humanitarian efforts.

12

Harry Truman

Image: Mike Gattorna

Middle name: S.

Harry S. Truman’s middle initial doesn’t stand for anything at all. His parents couldn’t decide between his two grandfathers, Solomon and Shippe, so they settled on "S." It’s a fitting story for a man known for making tough choices, including some of history’s most remembered.

13

Gerald Ford

Image: John Matychuk

Middle name: Lynch / Rudolph

Gerald Ford had two middle names in his lifetime. He was born Leslie Lynch King Jr., but after his mother remarried, his name was changed to Gerald Rudolph Ford Jr., in honor of his stepfather. He’s also the only president who never won an election but took office after Nixon’s resignation.

United States flag

For years, Americans loved telling the story of Robert G. Heft , the Ohio high school student who supposedly designed the modern 50-star flag as part of a class project in 1958. According to the tale, his teacher gave him a B minus, only to change it after President Dwight Eisenhower selected his design for the nation.

But real history turned out to be more complex. When Alaska and Hawaii officially joined the U.S. in 1959, the government received roughly 1,500 proposals for a new flag. In 2022, writer Alec Nevala-Lee dug deeper into the records and found that the final version was actually credited to the U.S. Army Institute of Heraldry, not a teenager from Ohio. The current version first flew in 1960 and has now lasted longer than any other American flag design. Those 13 stripes still honor the original colonies, while the 50 stars honor the states.

National anthem: "The Star-Spangled Banner"

You’ve probably sung it hundreds of times, but did you know that "The Star-Spangled Banner" didn’t begin as a song? Our national anthem started as a poem written during one of the most dramatic moments in early American history.

In September 1814, lawyer Francis Scott Key watched from a ship as British forces bombarded Fort McHenry near Baltimore, Maryland. The darkness was heavy, but at dawn, Key spotted the American flag still waving over the fort. That moment inspired him to write a poem called "Defence of Fort M’Henry," and the melody that kept matching in his head for the poem was borrowed from an old British drinking song called "To Anacreon in Heaven," from 1775. Ironic, considering the circumstances. The song became widely popular across the country, but it became the official national anthem in 1931, under Hoover’s presidency.

Pledge of Allegiance

For generations of Americans, the school day began the same: standing by a desk, hand over heart, facing the flag. But the Pledge of Allegiance has changed since it was first written in 1892 by Francis Bellamy for a nationwide Columbus Day Celebration.

The original version didn’t even mention the U.S. by name. Children simply said, "I pledge allegiance to my flag." Years later, in 1923, the words were changed so that every school kid, native or immigrant, would think of "the flag of the United States of America" when reciting it.

National bird: bald eagle

The first relevant appearance of the bald eagle wasn’t as the national bird; it was in the design of the Great Seal. This was in 1782, when the first committee appointed to design the task suggested this bird. The committee was formed by John Adams, Thomas Jefferson, and Benjamin Franklin, who was the only one who thought of the bald eagle as a bird of "bad moral character." Jefferson and Adams, instead, thought the bald eagle represented strength and independence, which seemed perfect for a young country trying to stand on their own. Moreover, the bird was unique to North America at the time, which made it feel distinctly American.

While it has appeared on the Great Seal, currency, and documents since that year, it was only in 2024 when it was designated as the national bird by an Act of Congress under Biden’s administration.

5

National motto: "In God We Trust"

Many Americans assume that E pluribus unum is still our national motto, but in 1956, that changed. The modern motto "In God We Trust" first appeared during one of the country’s darkest moments.

In 1864, as the Civil War tore the nation apart, several religious leaders urged President Lincoln to recognize God on American currency. Many believe the nation needed a symbol of faith and stability during such uncertain times. That same year, the motto appeared for the first time on a two-cent coin. But it was during the Cold War in the 1950s that the words took on new importance and officially became the national motto in 1956 when President Dwight D. Eisenhower signed the law.

6

Great Seal of the United States

The seal is printed on passports, official government documents, and even the back of the one-dollar bill. It features a complex design, and every detail on it means something.

The story of the Great Seal begins on the 4th of July, 1776, when the Continental Congress recognized that the new nation needed a seal to sign official documents. But that was just the beginning. Six years and three committees later, in 1782, Charles Thomson, Secretary of the Continental Congress, designed the seal we know today. The olive branch and the arrows held in the eagle’s talons denote the power of peace and war. The eagle faces the olive branch, but gazes toward the arrows, meaning it’s ready to defend. The 13 stars honor the colonies, and the escutcheon represents the eagle’s courage, along with the motto E pluribus unum, which was the official motto at the time.

7

National march: "The Stars and Stripes Forever"

Today, no Independence Day is complete without the bass of "The Stars and Stripes Forever," but its origin goes back to 1896. The national march began during a difficult trip across the Atlantic.

In 1896, composer John Philip Sousa was traveling home from Europe after learning that his close friend and business partner, David Blakely, had suddenly died. As Sousa paced the deck of a ship, a melody kept playing in his mind. By the time the ship reached New York, the entire march had taken shape. Inspired by the American flag waving as he returned home, Sousa later added the title we know today. But it was on December 10, 1987, that the march was named the "Official March of the United States of America" under Reagan’s administration.

National mammal: American bison

Long before highways crossed the country, bison herds thundered across the American grasslands from Texas all the way to Canada. But in the late 1800s, hunters began massively exterminating them to the point of extinction. Oddly enough, that’s when Americans began paying attention to them. Bison started appearing everywhere: on state flags like Wyoming’s, official seals, coins, and giant statues in cities across the country.

President Roosevelt became a big defender and helped create the American Bison Society in 1905 to protect the remaining herds. More than a century later, in 2016, Congress officially named the bison the national mammal of the U.S. and, today, more than 400.000 bison once again roam American grasslands.

9

National floral emblem: rose

Roses have been part of American life for generations. In 1986, President Ronald Reagan signed Proclamation 5574, declaring the rose the national floral emblem of the United States. This choice was highly practical since roses are grown in all fifty states and have been cultivated in American gardens since the nation’s inception. Reagan noted that Americans have long used the rose to "speak the language of the heart," making it a fitting symbol for the country.

10

National tree: The Mighty Oak Tree

The oak tree didn’t become America’s national tree through congressional debate alone. In 2004, the National Arbor Day Foundation opened the decision to the public, and Americans of all ages cast votes for their favorite tree over four months. From the start, t he mighty oak was the frontrunner, earning more than 101,000 votes and beating out redwoods, maples, and pines.

The choice came from the symbolism behind it. Oaks are some of the most widespread trees in the country, with more than 60 species stretching across the states. Besides, it carries roots in American history: The USS Constitution earned the nickname "Old Ironsides" because its oak hull was strong enough to repel British cannonballs during battle. Strong, enduring, the oak was a perfect match.
