Gateway Arch’s time capsule

The Gateway Arch, the 630-foot-tall monument located on the west bank of the Mississippi River in St. Louis, Missouri, is famous for being the world's tallest arch. But few people know about the secret hidden at its peak.

In 1965, before the final piece of the stainless steel arch was put in place, a time capsule containing the signatures of 762,000 St. Louis students and residents was welded into the keystone. Just one more fun fact added to the mystique of this midwestern icon!

Have you ever wondered where Hollywood's golden age films are preserved? Well, as it happens, they are not in the basement of some Tinseltown studio but more than 650 feet below the surface in a facility in Hutchinson, Kansas. Established in 1959, Underground Vaults & Storage specializes in storing a wide range of valuables, including paper documents and client records.

In addition, this site is a precious resource for the entertainment industry. Underground Vaults & Storage preserves—under optimal temperature and humidity conditions—film copies of classic cartoons, television programs like Friends , game shows, soap operas, and even the original reels of cinematic masterpieces like The Wizard of Oz and Gone with the Wind .

A ‘Big Basket’ building

Who says a building has to look traditional to be iconic? Why settle for an ordinary office building when you can work inside a basket? That's what the executives of the Longaberger Company, an American manufacturer and distributor of handcrafted maple wood baskets, thought when they relocated to Newark, Ohio, in 1997.

Their headquarters was designed as a seven-story building, a perfect replica of the company's top-selling product, the Medium Market Basket. The massive handles are attached to the structure with copper and wooden rivets, and the gold-leaf-plated tags each weigh 725 pounds. Though the building was a novelty, the company eventually abandoned it, and it is now listed for sale.

Empire State Building Wedding Club

Popping the question on top of the Empire State Building has become a cherished tradition in the United States. Thousands of couples travel from all over the country to get engaged at one of New York City's most iconic buildings. But did you know that you can also celebrate a wedding there?

Every February 14, a few lucky couples are granted the unique opportunity to exchange wedding vows at the building's 86th Floor Observatory. Since 1994, hundreds of couples have said "I do" at this breathtaking location, celebrating Valentine's Day at America's most romantic landmark.

A supernatural castle

Creativity, ingenuity, and perseverance can achieve extraordinary feats. Such is the case with Coral Castle, a massive limestone structure built by self-taught engineer Edward Leedskalnin in the early 20th century.

Located just north of Homestead, Florida, sits this construction built with stones larger than those at Stonehenge. Leedskalnin, who invested more than 28 years in this project, claimed that he raised it single-handedly using reverse magnetism and supernatural abilities. The truth is he probably used pulleys and other tools, but that doesn’t make it any less of a unique and original building that is a fascinating tourist attraction to this day.

Walt Disney's utopian city

Image: Paul Moody

Walt Disney was a visionary, and thanks to his infinite imagination today we have the most endearing characters and the best amusement parks in the world. But did you know that Disney originally envisioned his famous EPCOT Center as the blueprint for a larger utopian society?

EPCOT stands for Experimental Prototype Community of Tomorrow. Had Disney’s dream come to fruition, 20,000 people could have lived in a real, futuristic city complete with residential areas, shopping malls, factories, recreational parks, and a state-of-the-art multimodal road system to connect it all. Unfortunately, after his death in 1966, the company felt his original vision was a bit impractical. Instead, they created a theme park that captures the spirit of its creator, a permanent celebration of human achievement, from culture to technological innovation.

Secret codes

The CIA is a mysterious organization, so it's no wonder that there is a sculpture hiding secrets sitting right in the courtyard of the George Bush Center for Intelligence in Langley, Virginia.

Named "Kryptos," this large copper sculpture was installed in 1990 and holds a series of four encrypted messages. Only three of these codes have been cracked, while the fourth remains one of the most famous unsolved cryptograms in the world.

The paper house

It seems that the 1920s was a time of inventiveness, innovation, and originality in architecture. During this decade, the United States built the most impressive skyscrapers and, as we've explored, even a massive limestone castle. But a house made of paper? It seems almost impossible, doesn’t it?

Well, we are about to prove you wrong. In 1924, a mechanical engineer called Elis Fritiof Stenman built a summer cottage made almost entirely out of pasted, coated, or rolled-up newspapers. The only exceptions were the framework, floorboards, and shingles. The house is located in Rockport, Massachusetts, and, believe it or not, is still standing and can be visited.

Race into the sky

The Chrysler Building on the East Side of Manhattan in New York City was once the world’s tallest building, holding the title for 11 months. But did you know that it almost didn't make it? Industrial pioneer Walter Chrysler, who commissioned the project, wanted his building to be taller than the Eiffel Tower. Originally designed to be 925 feet tall , the imminent construction of other taller skyscrapers forced architect William Van Alen to revise his plans.

This competition for the title of the world’s tallest building became known as the " Race into the Sky ." To beat his opponents, Van Alen ordered a 125-foot spire to be built in secret. It would only be attached to the roof after the rival buildings were finalized. When it was finished in May 1930, the Chrysler Building reached 1,046 feet, making it the tallest man-made structure in the world at the time. Unfortunately, less than a year later, the Empire State Building would claim that honor.

Did you know the world's only undersea research laboratory is located in the United States? Sixty-six feet below the surface of the ocean off the coast of Florida lies Aquarius Reef Base, an underwater lab where researchers work for up to ten days at a time.

Aquarius is dedicated to the study and preservation of coral reefs, fish, and aquatic plants. The facility is currently operated by Florida International University and contains sophisticated state-of-the-art lab equipment.

Give me the time of day

A bridge that tells time? We are not kidding! When it’s not being used by pedestrians and cyclists to cross the Sacramento River in Redding, California, the Sundial Bridge at Turtle Bay serves as a giant timepiece.

The bridge's 217-foot support tower points north, and its shadow can be used to calculate the time. Designed by renowned Spanish architect Santiago Calatrava, it was completed in 2004. So now you know, if your watch breaks or your cell phone dies on your way to Turtle Bay Exploration Park, you don't have to worry, the Sundial Bridge will always tell you the time of day!

The Capitol Subway System

Few people know that a network of subway cars runs beneath Washington’s labyrinthine Congressional headquarters. The first Capitol Subway System opened on March 7, 1909, and has been transporting politicians seeking shelter from the weather—and curious onlookers—for more than a century.

The rails stretch for nearly a mile, connecting the United States Capitol to several congressional office buildings. While the public can ride the trains, the subway is restricted to congressional members and staff during votes.

Empire State Building

We’ll begin with what’s perhaps the most famous skyscraper in "The City That Never Sleeps". The Empire State Building speaks to the magnificence and grandeur of New York City: After all, it is named after the State of New York’s official nickname, "The Empire State".

At the time of its construction, the Empire State Building was the tallest building in the world, a title held for almost 40 years. Its exquisite Art Deco design and innovative architecture have turned it into an instantly recognizable icon. Perhaps more famously, it has been featured in unforgettable pictures like "Sleepless in Seattle" and "King Kong". Be honest: Whenever you see a picture of this building, can’t you almost see a humongous ape perched atop its antenna?

Flatiron Building

Image: Vidar Nordli-Mathisen

For many, the most remarkable feature of this iconic building is its unusual name, which comes from its also rather unusual shape. The Flatiron is considered a New York City institution, and its history is almost as inspiring as its groundbreaking design.

In its early years, the Flatiron was known by the derisive nickname "Burnham's Folly", since detractors believed that architect Daniel Burnham’s design was a laughable idea. History would prove Burnham right though, since the Flatiron is still one of the most instantly recognizable skyscrapers in the world.

Willis Tower

For any Chicagoan who might be reading this, we know that you probably still call this building the "Sears Tower", but we thought it would be appropriate to include the official new name of this iconic skyscraper. Located in the heart of the "Loop", the Willis Tower is a 110-story, 1,451-foot building that has truly earned its place in Chicago’s skyline.

Since its opening in 1973, Willis Tower has proudly held the title of the world’s tallest building for close to 25 years. Regardless, this juggernaut is still an American landmark and one of Chicago’s most visited tourist attractions.

Transamerica Pyramid

While most pictures of San Francisco’s skyline are usually dominated by the Golden Gate Bridge, visitors of "The City by the Bay" are frequently dazzled by this unusual yet breathtaking building. Completed in 1972, the Transamerica Pyramid was San Francisco’s tallest building until 2018, when it was surpassed by the Salesforce Tower.

Without a doubt, the most striking aspect of this building is its groundbreaking design: Just like San Francisco’s carefree spirit of independence, this building seems effortlessly innovative. It has been compared to other revolutionary designs, most notably to "the Shard" building in London.

Columbia Center

Image: Anthony Alexander

Formerly known as "the Bank of America Tower" (or BOAT for short), the Columbia Center was constructed in downtown Seattle in the early ‘80s: At the time, this imposing black skyscraper was the highest building on the West Coast. While most of this skyscraper is leased for private usage, it does house the highest public viewing area west of the Mississippi River.

The Columbia Center’s design produces a rather interesting effect: Since the building is composed of 3 separate segments joined by 2 setbacks, viewers from the street might believe the Columbia Center is made from 3 different towers set side to side.

The Chrysler Building

Image: Anthony Fomin

As you probably expected, many iconic skyscrapers from "The City That Never Sleeps" will be featured in this article. The Chrysler Building is an art-deco masterpiece located at the intersection of 42nd Street and Lexington Avenue, which holds the distinction of being the world’s very first supertall skyscraper.

This building was commissioned by (and named after) Walter Chrysler, head of the Chrysler Corporation, and its construction was marked by a friendly competition with the Empire State Building for the title of the world’s tallest building. In that sense, the Chrysler Building’s remarkable 1,046 feet height gave it this impressive title, albeit only for 11 months.

Wells Fargo Plaza

If you ever find yourself taking a stroll through Downtown Houston, you’ll definitely come across a gorgeous all-glass skyscraper. You can’t miss it: After all, the Wells Fargo Plaza is the tallest all-glass building in the entire Western Hemisphere, standing at an impressive 992 feet.

This skyscraper was formerly known as the Allied Bank Plaza and in, 1988, it was renamed to the First Interstate Bank Plaza. However, when in 1996 First Interstate Bancorp was bought by Wells Fargo, this skyscraper changed its name once again to the Wells Fargo Plaza we all know.

John Hancock Center

Image: Jonathan J. Castellon

Founding Father John Hancock truly deserves all the praise it can receive from the American people, so it stands to reason that he should have his name honored by a 1,128-foot supertall skyscraper. Located in the iconic "Magnificent Mile", the John Hancock Center was for a while the tallest building in Chicago, surpassed by the previously mentioned Willis Tower.

This skyscraper was completed in 1969 and it has remained a Chicago staple ever since. It houses several restaurants and offices, as well as approximately 700 condominiums. Interestingly, the John Hancock Center is the background on which the 1988 horror film "Poltergeist III" takes place: Posters for this film featured this skyscraper, with a menacing lighting bolt crossing the night sky behind it.

Bank of America Plaza

Just like the Empire State and the Chrysler buildings, the Bank of America Plaza is another wonderful example of Art Deco architecture located between Midtown and Downtown Atlanta. This gorgeous skyscraper is instantly recognizable thanks to its unusual color palette, and it holds the distinction of being the tallest building of any U.S. state capital.

If you are lucky enough to visit "the City in a Forest", try to visit the Bank of America Plaza at night. You’ll quickly notice that the stunning golden spire at the top of the building (which is actually shaped like the Plaza itself) glows alongside a gorgeous pyramid of girders, in a lovely orange hue that tries to resemble old street lights.

Home Insurance Building

We’ll end this article by honoring an iconic skyscraper that, while it is not still standing, lives on in the proud history of our country. Standing at 138 feet, the Home Insurance Building might not seem remarkably tall by today's standards but, at the time of its construction in 1885, this Chicago historical landmark became the world’s very first skyscraper.

Due to a decrease in its occupancy, the Home Insurance Building was demolished in 1931, alongside 5 other buildings, to make way for the site on which the Field Building now stands. However, this landmark’s legacy still stands, earning its well-deserved place in history as the father of the skyscraper.

Franklin D. Roosevelt, the 32nd president of the United States, delivered a phrase in his first inaugural address that would be remembered forever. On March 4, 1933, at the height of the Great Depression, he proclaimed, "The only thing we have to fear is fear itself," with the aim of inspiring a nation in crisis to embrace courage and hope.

"Ask not what your country can do for you…"

The Cold War, international tensions, and civil rights struggles were shaking the nation when John F. Kennedy delivered his unforgettable inaugural address on January 20, 1961. Calling on Americans to take personal responsibility and contribute actively to the nation, he gave one of the most famous lines in American history: "Ask not what your country can do for you—ask what you can do for your country."

"Speak softly and carry a big stick…"

F.D. wasn't the only Roosevelt with memorable quotes. Before him, Teddy Roosevelt made his mark, but he was a bit blunter. The 26th president first said, "Speak softly and carry a big stick; you will go far" in a public speech in 1901. With that line, he described his approach to foreign policy, which later became known as "Big Stick diplomacy."

"A house divided against itself cannot stand"

Abraham Lincoln gave us iconic words even before becoming president. In 1858, while accepting the Illinois Republican Party's nomination for the US Senate, he declared, "A house divided against itself cannot stand." The Civil War had not yet begun, but the nation was already deeply divided. This powerful line helped elevate Lincoln's reputation, paving the way for his election as president in 1860.

"We choose to go to the Moon"

As expected, John F. Kennedy appears more than once on this list. This time, with a phrase that would kick off one of the greatest achievements in US and human history: the moon landing. During a speech at Rice University on September 12, 1962, in Houston, Texas, he said: "We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard." And history proved him right.

"Mr. Gorbachev, tear down this wall!"

Ronald Reagan also gave the world memorable quotes, including this famous one addressed to Soviet leader Mikhail Gorbachev during a speech at the Brandenburg Gate in West Berlin on June 12, 1987. Two years later, the Berlin Wall was brought down by the citizens themselves.

"The buck stops here"

Displayed in his office, Harry S. Truman had the phrase: "The buck stops here." After assuming the presidency following Franklin D. Roosevelt's death, Truman had to face critical decisions at the end of World War II. The famous line reflected his belief in taking personal responsibility for decisions rather than shifting blame.

"Liberty, when it begins to take root…"

Washington shared this idea in 1785 in a letter to Alexander Hamilton, shortly after the end of the American Revolutionary War. In it, he clearly expressed his vision for the young nation, whose principles would be rooted in the power of liberty and freedom.

"If your actions inspire others to dream more…"

John Quincy Adams, the 6th President of the United States, gave us one of the most inspiring quotes: "If your actions inspire others to dream more, learn more, do more, and become more, then you are a leader." Thus, he defined leadership as a moral responsibility, one that motivates and uplifts others.

"Happiness and moral duty are inseparably connected"

In his 1796 Farewell Address, George Washington captured the guiding principles of his presidency with this phrase. For the first US president, fulfilling moral duties and, above all, acting with integrity were inseparable from true happiness.
