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

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

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

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

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

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

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

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

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!

Marlon Brando vs. Frank Sinatra

Frank Sinatra and Marlon Brando are names that hardly go unnoticed anywhere in the world. These stars of music and cinema crossed paths during the filming of Guys and Dolls in 1955, and it didn’t take long for a clash of egos. Brando’s method-acting style often conflicted with Sinatra’s more traditional approach, while Sinatra saw Brando’s performance as pure pretension. Their very different ways of thinking and working led to a long-standing animosity that lasted for years and, according to some sources, included everything from insults to threats.

2

Betty White vs. Bea Arthur

It’s hard to believe that these two women, who played best friends on The Golden Girls (1985-1992), couldn’t stand each other in real life. Apparently, Bea Arthur, who was more reserved, was often irritated by Betty White’s cheerful, outgoing humor. According to people who worked on the set, the two actresses didn’t get along at all, but they remained totally professional, and we have to admit that, on this side of the screen, you’d never know it.

3

Joan Crawford vs. Bette Davis

Joan Crawford and Bette Davis were divas of Hollywood’s Golden Age, both highly successful and Oscar winners. Ironically, it was their similarities that led to one of the most famous feuds in the industry, as professional competition slowly turned into personal resentment. In 1962, they finally worked together on What Ever Happened to Baby Jane? , and according to reports, fights, insults, pranks, and even acts of sabotage were constant throughout filming.

4

Debbie Reynolds vs. Elizabeth Taylor

Love triangles don’t exist only in fiction. And that’s what happened between Debbie Reynolds and Elizabeth Taylor. The two were close friends before Elizabeth had an affair with Debbie’s husband, singer Eddie Fisher. The scandal ended Reynolds’ marriage in the late 1950s and dominated headlines and magazine covers.

Surprisingly, it didn’t end there. Years later, Reynolds reached out, and the two actresses reconciled. Their bond was sealed when they worked together on These Old Broads (2001), a comedy written by Carrie Fisher, one of the daughters Reynolds had with Eddie Fisher.

5

Johnny Carson vs. Joan Rivers

American late-night television wouldn’t be the same without Johnny Carson and Joan Rivers. Carson was the king of TV, hosting The Tonight Show for 30 years, while Rivers was a frequent guest host. Their friendship ended when Rivers accepted her own competing show on Fox. Carson reportedly never forgave her and banned her from The Tonight Show for the rest of his life.

6

Sylvester Stallone vs. Arnold Schwarzenegger

Sylvester Stallone and Arnold Schwarzenegger are undeniable icons of action cinema, which boomed in the 1980s and 1990s. But the battles weren’t just on screen; they spilled into real life. The two actors developed a long-running rivalry fueled by intense professional competition to be seen as the ultimate action star and land the biggest roles. They often criticized each other on TV and clashed at public events, but over the years, tensions eased, and these rivals eventually became close friends.

7

Madonna vs. Elton John

The music world is not immune to feuds. In fact, one of the most famous rivalries unfolded in pop music between two giants of the genre: Madonna and Elton John. The fight began in the early 2000s, when Elton publicly criticized the Queen of Pop, accusing her of lip-syncing. Although the tension lasted for years, there is good news: in 2025, the British singer apologized to Madonna, and the two reconciled, announcing it in a post on her Instagram.

8

Richard Gere vs. Sylvester Stallone

The Terminator wasn’t Stallone’s only rival. The star of Rocky also had a major feud with Richard Gere that nearly turned into a real fistfight. Tension began while filming The Lords of Flatbush (1974), when Stallone reportedly felt Gere was showing off in his role and openly criticized him. Things boiled over during a lunch break in a car, when Gere splashed mustard on Stallone, who reacted by elbowing him and throwing him out of the vehicle. The incident ultimately led to Gere being let go from the film.

9

Magic Johnson vs. Larry Bird

Two NBA superstars collided in the 1980s. We’re talking about Magic Johnson and Larry Bird, who had different playing styles and approaches to the game and were constantly compared by the press and the public. This intense on-court rivalry eventually jumped off the court, creating real personal tension between them. Over time, however, both stars lowered their guard, grew closer, and ultimately formed a strong friendship.

10

Sarah Jessica Parker vs. Kim Cattrall

Although Carrie and Samantha were best friends on Sex and the City , the actresses behind them didn’t share that bond in real life. The rivalry reportedly began during filming, as they never got along. Kim Cattrall openly criticized the pay gap between Sarah Jessica Parker and the rest of the cast, and these professional tensions gradually turned personal. Cattrall later stated, "We were never friends," and after the series ended, their relationship did not improve.

Hidden bunker

Beneath the East Wing sits the Presidential Emergency Operations Center (PEOC), a heavily fortified bunker created during World War II for President Franklin D. Roosevelt. It was expanded during Harry Truman’s massive White House renovations from 1948 to 1952 and became one of the safest locations in Washington, D.C.

The bunker became widely known after the September 11, 2001, attacks, when Vice President Dick Cheney and senior officials were rushed underground by the Secret Service. It was eventually dismantled in October 2025 when the entire White House East Wing was torn down by work crews to make way for a new, modernized underground command center and a large State Ballroom

Indoor swimming pool

An indoor swimming pool was installed in 1933 by Franklin D. Roosevelt, who used swimming therapy to help manage the effects of polio. The pool was considered extremely modern for its time, with underwater lighting and advanced filtration systems .

Harry Truman, John F. Kennedy, and Lyndon Johnson all used the pool regularly. In 1970, President Richard Nixon ordered the space converted into the White House press briefing room, though the original pool structure remains hidden underneath the floor today.

3

Dentist office

Very few people realize the White House has had its own dental office since the Hoover administration in the early 1930s. The facility was placed in the basement so presidents could receive emergency treatment without leaving the building .

Historic photographs from March 10, 1948, show the office fully equipped before the Truman renovation began. Barack Obama later joked in an interview that he was surprised to discover "the whole chair" and dental setup hidden beneath the White House. The practice is still fully operational and in use today.

4

Private movie theater

The White House once contained its own private movie theater inside the East Wing. Created during Franklin Roosevelt’s presidency in the 1940s, the room was converted from a cloakroom into a screening space during wartime renovations .

Presidents have used the theater for both entertainment and diplomacy. Ronald Reagan frequently screened westerns there, while modern presidents have previewed major Hollywood releases before public premieres. The theater was demolished in October 2025 alongside the rest of the East Wing to make way for a new state ballroom.

5

Almost demolished during the Truman era

By the late 1940s, the White House had become dangerously unstable, physically speaking. Floors sagged, walls cracked, and parts of the building were close to collapse after decades of expansions and poor structural support .

President Harry Truman ordered a complete gut renovation from 1948 to 1952. The interior was almost entirely dismantled while the exterior walls were temporarily held in place with steel supports. The Truman family lived across the street at Blair House during the reconstruction.

6

Escape route for the Cold War era

During the Cold War, secret underground passageways and emergency routes were reportedly added beneath the White House complex to prepare for nuclear threats . Many details remain classified even today.

The reinforced underground network connected secure areas beneath the East Wing and surrounding government buildings. These emergency systems were especially strengthened during the Truman renovation as fears of atomic attack grew in the early 1950s.

7

The attic was used as wartime storage

During World War II, unused areas of the White House attic were used as storage for emergency supplies, documents, and wartime materials . Security concerns dramatically increased after the attack on Pearl Harbor in 1941.

The upper levels of the mansion were also used to protect historic furnishings and archives during renovation projects and wartime precautions. Many visitors never realize the White House includes hidden utility and storage spaces above the famous state rooms.

8

Secret floral workshop

The White House maintains a hidden floral design workshop operated by an official team of florists. They prepare thousands of flower arrangements each year for state dinners, diplomatic receptions, and holiday events.

The operation works behind the scenes to coordinate flowers with historic rooms, national traditions, and visiting foreign leaders . Designers often work overnight before major ceremonies so arrangements appear fresh for televised events and tours.

9

Forgotten rooms and artifacts

The White House contains dozens of lesser-known rooms rarely seen by the public, including old service areas, storage rooms, and spaces left over from earlier renovations . Some hidden corners still preserve traces of earlier administrations.

Historic artifacts are also stored throughout the mansion and its underground levels, including furniture, paintings, and decorative objects removed during renovations. Some pieces date back to the early 1800s and are noted in and out of public rooms over time.

10

Multiple underground levels

Most visitors never realize the White House extends far below ground level. In addition to the main floors, the complex includes sub-basements, mechanical systems, secure communications areas, kitchens, storage facilities, and emergency infrastructure.

Historians estimate the White House contains roughly 55,000 square feet and six levels in total . Much of the underground structure was reinforced with concrete and steel during the Truman renovation to improve security and stability.
