A change in plans

Image: Alexey Komissarov

Can a color be a worldwide celebrity? It seems so! This is the case of the famous "international orange" of the Golden Gate Bridge in San Francisco, California.

It's hard to imagine this iconic bridge in any other color. But believe it or not, it was once about to be painted in another hue.

The original idea was to paint the Golden Gate Bridge black with yellow stripes to make it visible to ships and planes. However, the sharp vision of consulting architect Irving Morrow changed the plans. When he saw the reddish color of the primer used on the iron, he realized that this color would work much better and would also give the imposing structure an original touch.

Too good to be true?

We all know that incredible creatures and breathtaking landscapes await us in Yellowstone. You probably also know that this amazing area that covers more than 3,400 square miles in parts of Wyoming, Montana, and Idaho was the first national park in the United States. Not only that, it was actually the first national park in the entire world!

But, while it's totally famous and celebrated today, there was a time when only a few knew about this place. Early explorers who walked Yellowstone in the 19th century wrote detailed journals about what they saw and experienced there, but when they returned, they found that people didn't believe their stories. We have to admit that those skeptics had a point; such a beautiful place seems out of this world!

Capitol's subway

Nobody can deny the metro system is great. Its speed and efficiency allow thousands of people around the world to get to their homes and jobs every day. Did you know that the members of the U.S. Congress have their own subway system right underneath the Capitol building?

That's right! Under the impressive structure that houses U.S. Representatives and Senators lies an entire subway system. This allows workers there to access different parts of the complex in a matter of seconds. It must make things easier on busy days, don't you think?

The final detail

But not all of the Capitol's surprises are underground; some are in plain sight. We're talking about the spectacular dome that crowns the famous neoclassical building in Washington, D.C. While the dome is a symbol of our country today, there was a time when the Capitol Building didn't have this gracious final detail.

The construction was considered completed in 1800. However, one last touch was still needed. In 1824, the first and smaller dome arrived, made of wood. Finally, it was replaced in 1866 by the impressive dome we see today, which stands an incredible 288 feet high and is made of cast iron, brick, stone, and copper.

A misspelling?

The Liberty Bell must be one of the most recognized icons of the United States. Preserved as a symbol of our Independence, everyone can visit the famous bell at the Independence Hall in Philadelphia, Pennsylvania.

In addition to its well-known history and its famous "crack," this bell has even more hidden details to discover. When you read the inscription on the Liberty Bell, you'll be able to read "Pensylvania" instead of "Pennsylvania." While you could think that those in charge of inscribing the bell weren't paying attention, it wasn't actually a misspelling; it was one of the accepted spellings for Pennsylvania in those days.

Hollywood(land)

Whether in person or through the screen, we all had the chance to see the legendary Hollywood sign over Mount Lee in Los Angeles, California.

But, while this landmark is recognized around the world today, it didn't always look as we see it now. The Hollywood sign had several changes throughout its history. It was first erected in 1923 as an advertisement for a real estate development. At the time, it read "Hollywoodland" and even had lights, illuminating the entire area at night.

Many things happened in our country before 1949, when the last four letters were removed, leaving just the current "Hollywood."

Good things take time

As we grow older, we understand one truth: good things often take time. While patience seems to be in short supply these days, it was certainly in abundance for those who built the impressive Mount Rushmore National Memorial, one of our most famous attractions.

The construction of this imposing monument that features the faces of George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln began in 1927 and took 14 years to complete. Carving four 60-foot-tall heads on a granite hill is no easy task. But, on top of that, some budget difficulties slowed down the process even more.

Mount Rushmore's secret door

Mount Rushmore National Memorial has more secrets to disclose! Although not visible to the naked eye, there is a particular detail among the heads of Washington, Jefferson, Roosevelt, and Lincoln. Want to know what it is?

If you haven't heard about it, this might surprise you: there is a small door right there on Mount Rushmore. Mysteries everywhere! The door leads to a chamber known as the "Hall of Records." According to the plans of sculptor Gutzon Borglum, this spot would hold important documents and objects of our history.

Time capsule

Besides being the tallest human-made monument in the United States and also the tallest arch in the world, the famous Gateway Arch in St Louis has much more to offer.

During its construction in the 1960s, a curious detail was placed inside its iconic metal structure. At the base of the monument, you can find nothing less than a time capsule!

The capsule, which contains various artifacts and relics from our country's history and culture, was thought to give future generations an idea of what the world and the United States were like in those days.

19th-century graffiti

At 555 feet tall, the Washington Monument is one of the most imposing in our country. But besides its height, this landmark also possesses a couple of surprising facts.

It might seem that graffiti is a modern artistic expression that has only been around recently, but this isn't the case, and the Washington Monument is proof of that. At the structure's base, there is a series of graffiti made in the 19th century, during the Civil War.

That's right! Many people and soldiers passing by at the time left signatures, dates, and patriotic messages inscribed on the famous obelisk, and some of them are still visible!

"Here’s Johnny!" - The Tonight Show Starring Johnny Carson

The Tonight Show is one of the longest-running and most influential programs in television history. The late-night show premiered in 1954, but Johnny Carson took over in 1962 and became the face of the show for three decades. It was Ed McMahon, Carson’s longtime sidekick and announcer, who gave birth to the iconic introduction: "Heeeeeere’s Johnny!" The phrase took hold so firmly in American culture that it was referenced endlessly across other shows and media, most famously parodied to terrifying effect by Jack Nicholson in Stanley Kubrick’s The Shining (1980).

"What’chu talkin’ ’bout, Willis?" - Diff’rent Strokes

It’s impossible not to picture Gary Coleman’s face when you hear "What’chu talkin’ ’bout, Willis?" The line, uttered by Arnold (Coleman) to older brother Willis (Todd Bridges), became so famous that it’s still used today to express confusion, even by young people around the world who don’t know it comes from the NBC sitcom Diff’rent Strokes (1978–1985). The catchphrase helped catapult Coleman to international fame, but it was repeated so often that, by the later seasons, he admitted he sometimes refused to say it.

3

"Ayyyyyy!" - Happy Days

Yes, the power of a catchphrase can be so strong that some of the most memorable ones are just one consonant-free syllable. A perfect example is the signature line of Arthur Fonzarelli, A.K.A. Fonzie, or "The Fonz," from Happy Days (1974–1984). Played by Henry Winkler, Fonzie was the coolest guy on TV, so all it took was a leather jacket, a thumbs-up, and an "Ayyyyy!" to make him immortal.

4

"Dy-no-mite!" - Good Times

Actor Jimmie Walker rose to fame playing J.J. Evans on the American sitcom Good Times (1974–1979). His clever and energetic character had a trademark: "Dy-no-mite!", his exclamation of excitement, approval, or surprise. The line became so famous that it appeared everywhere, from T-shirts to posters, and for many viewers, it’s the thing they most remember about the show.

Although the line was undeniably a hit, the actor admitted in later interviews that he wasn’t entirely sure it would take off. Who could have predicted what was coming?

"I love it when a plan comes together!"- The A-Team

"I love it when a plan comes together!" was the iconic catchphrase delivered by George Peppard’s character in The A-Team (1983–1987). At the end of many episodes of the action series, Lieutenant Colonel John "Hannibal" Smith would light or just hold his cigar as he delivered the line, signaling that his plans (usually elaborate, risky, and a little over the top) had worked out perfectly. Over time, the phrase became part of popular culture and is still used today whenever everything falls into place.

6

"Book 'em, Danno" - Hawaii Five-O

"Book ’em, Danno" was the iconic line delivered by Jack Lord’s character, Detective Steve McGarrett, to his partner Danny "Danno" Williams (played by James MacArthur) on Hawaii Five-O (1968–1980). The utterance often came at the end of an episode when the bad guy had finally been caught. It became hugely popular and turned into a cultural shorthand for "case closed" in the 1970s.

7

"Lucy, you got some 'splaining to do!"- I Love Lucy

Desi Arnaz and Lucille Ball played the ultimate sitcom couple, Ricky and Lucy Ricardo, on I Love Lucy (1951–1957). Whenever Lucy got caught up in one of her classic schemes or hilarious misunderstandings, Ricky would step in to deliver some version of "Lucy, you got some ‘splaining’ to do!"

Even though the line was never delivered exactly the same way, Ricky would always demand an explanation in similar terms, with variations like "Lucy, something needs ‘splaining’" or "What needs ’splainin’?"

"Is that your final answer?" - Who Wants to Be a Millionaire?

Maybe it’s just nostalgia, but it’s hard not to feel the tension when you hear "Is that your final answer?" That classic line from Who Wants to Be a Millionaire? originated with Chris Tarrant, the original host of the British version, which debuted in 1998. But it was Regis Philbin, host of the American version (which premiered in 1999), who helped the phrase achieve worldwide fame.

The question added a moment of suspense, often making contestants second-guess themselves. Over time, its impact went far beyond the game, becoming an indisputable part of the cultural lexicon

9

"Live long and prosper" - Star Trek

You may remember Leonard Nimoy’s voice as Spock delivering his signature "Live long and prosper" in the original Star Trek (1966–1969). As a traditional Vulcan greeting, the line was often paired with the iconic hand gesture, where the fingers split to form a "V" shape. The phrase went on to transcend generations, which makes it even more surprising that it wasn’t part of the original script; it was Nimoy who came up with both the gesture and the phrase for the show.

10

"Norm!" - Cheers

Cheers (1982–1993) is one of those shows that’s hard to forget, and anyone who’s seen it will instantly remember the shout of "Norm!" This was the familiar greeting from the bar’s staff and regulars every time Norm Peterson, played by George Wendt, walked through the door. Norm is one of the few characters to appear in all 275 episodes of the series, so that moment became a beloved and frequent (very frequent) ritual.

Olympic National Park

Let’s kick off our ranking with Olympic National Park, located in the state of Washington. The park was designated as a National Park in 1938 during Franklin Roosevelt's presidency.

What makes this National Park so remarkable? Well, it has three distinct ecosystems : the temperate rainforest (which is the only one in the contiguous United States), the rugged coastline, and glaciated peaks. This variety of landscapes brings a rich biodiversity to the area that is definitely worth visiting!

Joshua Tree National Park

We know it’s in the name, but did you know Joshua Trees aren’t actually trees ? They belong to a subgroup within the yucca species. These plants can live for over 150 years, and you can find them in this park, among other places.

Similar to Olympic National Park, this park features three separate ecosystems: a part is within the Colorado Desert, it also includes California juniper, the San Bernardino Mountains, and the Mojave Desert where you’ll find the famous Joshua trees.

If that wasn’t enough reason to pay a visit, you have to know that this park has one of the darkest skies in Southern California, providing an excellent opportunity to spot the Milky Way galaxy!

3

Grand Teton National Park

Image: Michael Kirsh

Located in Wyoming, this National Park is home to what is believed to be the youngest mountain range in the Rocky Mountains: they are only between six and nine million years old!

In Grand Teton, you’ll find incredibly tall mountain peaks (the highest reaching 13,770 feet) and a wide variety of wildlife, including grizzly bears, gray wolves, coyotes, moose, and more.

Established in 1929, the park was later combined with the Jackson Hole National Monument, in 1943. Today, the town of Jackson Hole, located to the south of Grand Teton is the main hub of activity in the area. And, if you visit, you can actually make it a two-for-one trip because it's only 10 miles away from Yellowstone National Park, which will be featured later in this list!

4

Acadia National Park

Image: Raphael Assouline

Acadia National Park receives over 3.5 million visitors each year, and that has secured a position in this ranking. The park features granite mountains, rocky coastlines, ponds, lakes, and all kinds of plants and wildlife. It is an Atlantic shoreline beauty!

The park was first named Sieur de Monts National Monument by President Wilson in 1916. In 1919, it was renamed Lafayette National Park, but that wasn’t the end of it. In 1929, the name officially changed to Acadia National Park, honoring "Arcadia," a region in Greece that is pretty similar to the park!

5

Yosemite National Park

Image: Jota Lao

Although it is not one of the top three most visited national parks in our country, the park’s popularity is undeniable because it was the one park that paved the way for the National Park System as we know it today. The establishment of this area as a national park is largely credited to John Muir, a Scottish naturalist who recorded the beauty of the area and raised awareness around it.

Today, Yosemite covers an area of 759,600 acres and is home to granite cliffs, giant sequoias, mountains, glaciers, streams, and waterfalls. It is predominantly classified as wilderness and is, of course, a protected area.

Rocky Mountain National Park

This national park is a gem in Colorado and the 4.5 million visitors it receives each year is a testament to that. The park boasts rugged mountain terrain, alpine lakes, and dense forests—making it simply breathtaking.

It was established in 1915, and it is home to Longs Peak , which stands at an impressive 14,259 feet, and the famous Trail Ridge Road, the highest paved road in the country! Besides, this park is home to over a thousand types of wildflowers and 280 species of birds, just to mention a few details that make it an incredible place in America!

7

Yellowstone National Park

Image: Nicolasintravel

Yellowstone National Park is a true icon of the American West, and with over 4 million visitors each year, it’s easy to see why. The park lies across Wyoming, Montana, and Idaho, and it showcases wilderness at its best: geysers, hot springs, rivers, and canyons co-exist within the area. It is also home to the famous Old Faithful , the visitor’s favorite: an ever-erupting geyser!

Yellowstone holds the honor of being the very first national park in the world, having been established in 1872. The idea of preserving this vast and unique landscape for future generations was revolutionary at the time, and it laid the groundwork for the global national park movement. Have you had the chance to visit it yet?

8

Zion National Park

Image: Jamie Hagan

This deserted wonderland is located in Utah and it is known for the towering red sandstone cliffs and deep canyons as well as the glowy rock formations .

Established in 1919, it was Utah’s first National Park, and it is home to over 100 miles of trails. Car access to the park is limited, so there are plenty of hiking trails within the area. Moreover, this park is home to the second largest freestanding arch in the world which is 287 feet in length.

If you visit the park, you will surely make a stop at the Zion Lodge. But, did you know this is not the original construction? The original structure was struck by a fire in 1960, so the one you see today is actually a second version of it!

9

Grand Canyon National Park

Image: Michael Kirsh

You probably thought this was the most visited park in our country, but there’s another that holds that title! As for the Grand Canyon, it still is incredibly popular, and receives over 6 million visitors every year!

Located in Arizona, the Grand Canyon stretches 277 miles long and a mile deep. It was established in 1919 and it is only second in the ranking due to the powerful and awe-inspiring sights. That’s why it is one of the Seven Natural Wonders of the World .

Across the canyon, visitors can enjoy the Colorado River, where water carves layers of rock that have been in the area for millions of years. No words can capture its beauty, you just have to visit it to understand it.

10

Great Smoky Mountains

To close our ranking, we present the most visited National Park in America: the Great Smoky Mountains. Did you guess it right? Even if you did, you would have never guessed the number of visitors right: a shocking 13 million visitors a year ! Now, the reasons? Almost as many as its visitors.

The National Park was established in 1934, but the mountains that are housed in it were formed millions of years ago. It spans the borders between North Carolina and Tennessee and it is best known for its mist-covered mountains, lush forests, and the remarkable biodiversity of plants and animals.

With 800 miles of hiking trails, among which you’ll find the Appalachian Trail, preserved historic buildings, and peaceful retreats, it’s no surprise that the number one park on our list is also a favorite among visitors. Do you agree?
