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.

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

Image: Daderot, Public domain, via Wikimedia Commons

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

Image: roberto_bellasio

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.

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!

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.

"Buffalo Bill" Cody

If we had to name the most famous cowboy in history , Buffalo Bill Cody would probably be a top contender. Throughout his lifetime, Cody greatly contributed to shaping the image we have of the American West.

Born in Iowa in 1846, he earned his nickname while working for the Union Pacific Railway, where railroad workers were amazed by his hunting skills. But history had bigger plans in store for Cody, and he would soon become an actor , traveling throughout the eastern United States performing plays based on stories of the Wild West for more than 30 years.

Eventually, poor business management and a certain change in popular interests led Buffalo Bill to ruin and he retired from show business just two months before his death in 1917. He was, however, mourned by millions of people who considered him a hero.

John Henry "Doc" Holliday

Image: Mehmet Turgut Kirkgoz

John Henry "Doc" Holliday was born in 1851 in Griffin, Georgia, into a wealthy family. He earned his Doctor of Dental Surgery degree in Philadelphia but was shortly thereafter diagnosed with tuberculosis and advised to live in the drier, hotter climate of the West.

In Dallas, Texas, he pursued his trade as a dentist but also discovered saloons and whiskey. Soon, realizing that gambling could be much more lucrative than dentistry, he began his professional gambling career.

The rest of his life was spent among crooks, gunfights, and jailmates in New Mexico, Arizona, and California. At only 36 years old, his lungs could not keep up with his gunslinging way of life and he finally met his death in 1887 in a hotel bed in Colorado. It is said that his last words were, "This is funny."

Butch Cassidy and The Sundance Kid

Image: yavuz pancareken

The lives of Butch Cassidy and The Sundance Kid became legendary pretty quickly. As early as 1903, their exploits inspired the first modern film —Edwin S. Porter's _The Great Train Robbery_— and since then, their adventures have not ceased to be portrayed by popular culture. In a way, they symbolize the definitive end of the romanticized Western era at the hands of 20th-century industrialization and urbanization.

Both cowboys were members of a gang known as "The Wild Bunch," which earned them a reputation as bank and train robbers. According to lore, after several years of crime and run-ins with the law, the bandits managed to escape to Latin America. Eventually, they were caught and killed in Bolivia in 1908. The fact that their graves were never found helped fuel the myth that they had, in fact, returned to the United States and lived in anonymity for many more years.

Jesse James

Image: Steve

Jesse James's life is one of the most emblematic of the Wild West. His criminal career began after his involvement with pro-Confederate guerrillas during the Civil War. Along with the Younger brothers, he created a gang with which they robbed banks, trains, stagecoaches, and stores from Iowa to Texas and from Tennessee to California.

It is believed that throughout the years they netted more than a quarter of a million dollars. Despite the gory nature of their heists and murders, the gang often had public sympathy.

Jesse's death is as controversial as his life. At only 34 years old, he was shot in the back by one of his gang partners, who hoped to obtain a state reward in exchange for his betrayal. The public was not happy with the government conspiring to assassinate a citizen, no matter how criminal, and the matter became a scandal, resulting in Jesse James's rise to mythical status.

Annie Oakley

From an early age, Phoebe Anne Oakley Moses, better known as Annie Oakley, took up hunting to help support her family. At the age of fifteen, she won a competition against the famous marksman Frank Butler, to whom she later married. Together, they appeared in several exhibitions across the country and, in 1885, joined Buffalo Bill's Wild West show.

Annie was able to open the edge of a letter, shatter glass balls thrown in the air, and hit dimes held between her husband's fingers or apples placed in her poodle's mouth by shooting from 30 paces away. Her life was so rich and fascinating that she was the inspiration for several movies and plays.

Billy the Kid

According to legend, Henry McCarty, better known as Billy the Kid, killed at least 21 people during his career as a notorious outlaw in New Mexico. However, he cemented his place in the pantheon of frontier legends not so much for his murders as for his personality and incredible marksmanship skills.

Born in the late 1850s in the Irish slums of New York City, McCarty had to reinvent himself as a gunslinger after the death of his mother when he was just a teenager. His life and the events surrounding his death at the hands of legendary lawman Pat Garrett were immortalized in numerous films, books, and songs. In fact, Billy the Kid holds the record as the most portrayed individual in cinematic history.

Lucille Mulhall

By 1900, split riding skirts allowed women to compete in rodeos without shocking Victorian-era audiences. But the truth is that women have been participating in exhibitions even in the early days of the Old West.

Lucille Mulhall is considered America's first legendary cowgirl. Born in 1885, Lucille grew up on her family's ranch in Oklahoma, where she acquired her incredible cattle-roping skills. She began performing in shows as a teenager and, throughout her career, competed in many rodeos, setting a few roping world records.

Belle Starr

Perhaps the most famous female gunslinger in the history of the West was Myra Maybelle Shirley Reed Starr, better known as Belle Starr. Born in Missouri in 1848, Belle had a fairly well-to-do childhood and was a bright student. However, when her family moved to Texas after the Civil War, the young girl stumbled upon the James-Younger gang. After falling in love with Cole Younger, she became a member of the gang.

That love affair didn't last long, but a few others followed, which led her to live outside the law for the rest of her life. Her alleged riding and gun skills increased her fame throughout the country, turning her into a legend.

Wyatt Earp

Wyatt Earp belonged to a large family whose members were famous for being gunfighters, gamblers, bison hunters, miners, and lawmen. While all were notorious Wild West characters, it was Wyatt's exploits that have gone down in history. His life is testimony to the ambiguity that prevailed at a time when there was no distinction between upholding the law and transgressing it.

After a long life traveling the American West as a deputy sheriff, bounty hunter, and saloon owner, in 1905 Wyatt settled permanently in Los Angeles, California. He became a film consultant in Hollywood, befriending producers, directors, and actors. It is even said that John Wayne took Earp’s stories as inspiration for some of the tough characters he portrayed on the big screen.

"Wild Bill" Hickok

Image: Turuncu Sakal

James Butler Hickok, better known as "Wild Bill," is a legendary folk hero thanks to the many stories that romanticized his life as a soldier, gunslinger, gambler, marshal, and actor. Over the years, his adventures have been retold numerous times in pop culture. The truth is that Hickok did more in his thirty-nine years of life than most who lived twice as long.

Since his birth in Illinois in 1837, he is said to have been involved in some of the most dramatic and, at the same time, most spectacular events in the history of the Wild West. His death, unsurprisingly, is also legendary. In 1876, while playing a game of poker in a saloon in Deadwood, Dakota Territory, a man named Jack McCall shot him in the back of the head. The cards he was holding at the time —two pairs of Aces and black Eights— became the well-known "dead man's hand."

Locomotive steam-engine for rail (Patent #1)

Image: National Archives at College Park - Textual Reference, Public domain, via Wikimedia Commons

Between 1790 and 1836, the United States granted 9,802 patents that were not awarded on their merits and didn’t have an identification number. The Patent Act of 1836, which established the official Patent Office, aimed to make the system more transparent. Among other reforms, it introduced a numbering system for easier identification.

This system started on July 13, 1836, and remains in effect today. United States Patent No. 1 was issued to John Ruggles —an inventor, attorney, and senator from Maine—for improvements in locomotive traction.

Anesthesia (Patent #4,848)

Image: National Library of Medicine

How did patients endure surgery before anesthesia? Before the discovery of an effective anesthetic, surgery was synonymous with excruciating pain. Many large hospitals placed their operating rooms in isolated and remote sections of the hospitals so patients’ screams couldn’t be heard. Alcohol, opium, and even hypnotism were tried as methods of pain relief, but these had little effect.

Fortunately, we no longer have to endure such experiences, thanks to a Boston dentist named William T. G. Morton, who—along with Charles T. Jackson—received the first United States patent for an anesthetic in November 1846.

Buoying vessels over shoals (Patent #6,469)

Image: invented by Abraham Lincoln. Issued by United States government Patent Office, Public domain, via Wikimedia Commons

This may be the most unique patent ever issued by the United States Patent Office: it is the first and only U.S. patent granted to an inventor who later became president. Although at least three presidents—George Washington, Thomas Jefferson, and Abraham Lincoln—were inventors, Lincoln is the only one who formally applied for and received a patent .

In 1849, he was awarded Patent No. 6,469 for a flotation device designed to lift boats over shoals and other obstacles in the water. While the invention itself had little bearing on his election, Lincoln’s inventive mindset and mechanical curiosity served him well during his presidency. Although the device was never commercially produced, his appreciation for innovation helped shape the nation's future.

Beehive (Patent #9,300)

Image: Bianca Ackermann

Beekeeping arrived in America with the early settlers, and by the end of the 18th century, bee colonies were widespread. However, early efforts met with only partial success.

The first U.S. patent for a practical and effective movable-frame beehive—which revolutionized traditional methods of beekeeping—was granted to American apiarist, clergyman, and teacher Lorenzo Lorraine Langstroth on October 5, 1852. His invention of the "bee space" laid the foundation for all modern beekeeping and hive management.

Elevator (Patent #31,128)

Image: Copie de gravure ancienne, Public domain, via Wikimedia Commons

The New York skyline would look very different today had it not been for the invention of the elevator. The man responsible for the forerunner of the modern elevator was American industrialist Elisha Graves Otis , who, on January 15, 1861, received the first U.S. patent for a safety-type passenger elevator.

The concept of vertical travel was not new. However, the first successful passenger safety elevator was installed in 1857 by Otis in the E. V. Haughwout & Company building, a department store in Manhattan. Otis also held patents for other inventions, including railroad trucks and brakes, a steam plow, and a bake oven. But it was the elevator with its safety feature that brought him fame and his sons great fortune.

Lock (Patent #31,278)

Image: Parastoo Maleki

The idea of the lock probably stems from the time man first acquired goods he wanted to safeguard from others. However, the first commercially successful modern lock and key system was invented by American mechanical engineer and metalsmith Linus Yale Jr., who received a U.S. patent in 1861.

Yale developed several types of locks, including the Yale Double Treasury Bank Lock, created at the request of the U.S. government. These designs brought him nationwide recognition, but the invention that made him truly famous was the pin-tumbler cylinder lock . Yale died just a few years after receiving his patent. However, every lock and key produced by the Yale & Towne Lock Company since then has proudly carried the Yale name.

Barbed wire (Patent #157,124)

Image: Lexis Chadwick

In an age of video surveillance, barbed wire might seem obsolete. Yet it was crucial to the settlement of the American plains in the late 19th century—and it remains widely used around the world today .

On November 24, 1874, Joseph F. Glidden, a farmer from Illinois, received a U.S. patent for the first commercially successful barbed wire . While several earlier patents had been granted for wire fencing, it was Glidden’s design that proved durable, affordable, and easy to mass-produce—making it the dominant form of fencing on the frontier**.**

Air conditioner (Patent #808,897)

Image: Prasopchok

On those hot and humid days of summer, we should all be thankful for the work of Willis Haviland Carrier, often called the father of air conditioning. For his efforts, he received the first U.S. patent for a modern air conditioning system on January 2, 1906.

Air conditioning is a complex process that involves refrigeration, dehumidification, air purification, and circulation. Before Carrier’s invention, various individuals had worked on these individual components. But it was Carrier, an American engineer, who successfully integrated them —focusing on the crucial relationship between temperature and humidity.

Airplane (Patent #821,393)

Image: John T. Daniels, Public domain, via Wikimedia Commons

Orville and Wilbur Wright are credited with achieving the first controlled, manned flight in history. For their pioneering work, they received the first U.S. patent for an airplane, issued on May 22, 1906.

Many had been intrigued by the idea of human flight before them. However, it was the Wright brothers who succeeded in building, flying, and promoting the world's first successful airplane —an invention that revolutionized transportation.

10

Bakelite (Patent #942,809)

Image: Call Me Fred

The modern plastics industry wouldn’t exist without Belgian-American chemist Leo Hendrik Baekeland , who received the first U.S. patent for a thermosetting plastic in 1909. Before him, others had attempted to produce synthetic resins but were unsuccessful.

Baekeland corrected his predecessors’ mistakes. The result was the first thermosetting resin —one that, once set, would not soften under heat. Bakelite was the first in a long series of resins that shaped the U.S. economy, paving the way for materials such as cellophane, acetate, vinyl, Plexiglas, acrylic, Formica, and polyester.

Frozen food (Patent #1,773,080)

Image: United States Patent Office (Clarence Birdseye, inventor)., Public domain, via Wikimedia Commons

Do you know where the name Birds Eye Frozen Food comes from? From its inventor! In 1930, American entrepreneur Clarence Birdseye received the first U.S. patent for this type of product.

Food preservation has been a concern since the beginning of time. Techniques such as salting, pickling, smoking, curing, canning, and later inventions like the icebox and home refrigerator have all contributed to preserving food.

However, one of the most successful methods was developed and commercialized by Birdseye. His process involved quick-freezing meat, seafood, vegetables, and fruit in convenient packages without altering their original taste. Birdseye’s name became a household word, and his innovation created a multibillion-dollar industry.

Instant photography (Patent #2,543,181)

Image: Missouri Historical Society, Public domain, via Wikimedia Commons

When we think of instant photography, Polaroid is often the first name that comes to mind. But how much do we know about the man behind the company? American scientist, inventor, and co-founder of the Polaroid Corporation, Edwin Herbert Land , was granted the first U.S. patent for a one-step photographic process in 1951.

While on vacation with his family, Land conceived the idea for a camera and film that could produce an immediate photograph. In 1948, the first Polaroid Land Camera went on sale, though without much public approval. Polaroid continued to improve the Land Camera and, in 1965, introduced the affordable Swinger model , which became an immediate success. Throughout his life, Land was granted more than 533 patents, was inducted into the National Inventors Hall of Fame, and received the Presidential Medal of Freedom.
