It was built for the Seattle World’s Fair

The Space Needle wasn’t supposed to be a permanent monument. It was completed in 1962 specifically for the Seattle World’s Fair, an event aimed to highlight science, technology, and forward-looking design. During the fair, the tower helped visitors orient themselves within the Seattle Center grounds and served as a central meeting point. After the fair ended, the building was not dismantled, as many other fair structures were. Instead, it remained open to the public and gradually became a regular part of the city’s skyline.

The original colors had distinctive Space Age names

When the Space Needle first opened, its paint scheme reflected the era’s optimism about technology and space exploration. The main tower was painted Astronaut White, while the central core used a darker tone called Orbital Olive. Accent areas were finished in Re-Entry Red, and the top featured a warm, yellow-orange color called Galaxy Gold . These names were officially used at the time and appeared in design documents and promotional materials. Although later renovations replaced this scheme with more neutral colors, the original palette shows how strongly the tower’s design was tied to early 1960s ideas about the future.

Elvis was there

Not long after it opened, the Space Needle entered American pop culture. Elvis Presley filmed scenes at the tower for the movie It Happened at the World’s Fair , which was released in 1963. The filming took place shortly after the 1962 World’s Fair, when the structure was still new. At that time, many Americans had never traveled to Seattle, and television and movies were major sources of information about distant cities. Hence, the film helped introduce the Space Needle to a nationwide audience.

It was inspired by a UFO

The building’s most recognizable feature, the round observation deck, was shaped with intention. Designers chose a wide, circular form that reflected the Space Age themes common in the late 1950s and early 1960s. At the time, images of spacecraft and flying saucers appeared often in popular magazines, films, and exhibitions. The Space Needle’s top was meant to echo those ideas in a way that was easy to recognize from a distance. This design helped distinguish the tower from older observation structures and aligned it closely with the forward-looking message of the World’s Fair.

It was built in 400 days

Image: Andy Li

Speed mattered. Construction began in 1961, and the entire tower was completed in roughly 400 days so it could open on time for the World’s Fair in 1962. This schedule required crews to work in carefully planned stages, with steel sections fabricated off-site and assembled quickly once delivered. Concrete for the foundation and core had to be poured and set on a tight timeline. Despite the fast pace, engineers followed existing building standards, and inspections were carried out to ensure the tower could safely handle weight, wind, and daily public use.

Forget the elevator, take the stairs

Image: HAYOUNG CHO

Most visitors take the elevator, but the Space Needle also has stairs, 848 of them, from the base to the observation level. The stairs are primarily used for maintenance and special events rather than daily tourist access. Structurally, the tower is held together by tens of thousands of bolts and rests on a deep concrete foundation. Engineers designed the foundation and central core to withstand high winds and seismic activity, which are common in the Pacific Northwest. These construction details are not visible to most visitors, but they play a key role in keeping the tower stable and open to the public year after year.

It harbored a secret time capsule from the 1980s

Image: Mick Haupt

In 1982, staff placed a time capsule inside one of the Space Needle’s steel beams without a public announcement. The capsule was sealed and left in place as part of a routine update, rather than a formal ceremony. It remained hidden for more than thirty years until it was rediscovered and opened in 2017. Inside were everyday items from the early 1980s, including handwritten letters, photographs, and postcards. Several of these items were saved and included in a new capsule, which is planned to be opened in 2062 to mark the tower’s 100th anniversary.

It was the site of a famous April Fools’ prank

Image: Ben Mater

In 1989, a local television station aired a report claiming the Space Needle had collapsed. The segment was intended as an April Fools’ joke and included on-screen text explaining that it was not real. Even so, many viewers did not notice the disclaimer or tuned in late. Emergency phone lines and the station’s own offices received hundreds of calls from concerned residents and relatives. The reaction showed how familiar and important the Space Needle had become to people in Seattle and beyond.

There’s a restaurant at the top

Dining has always been part of the Space Needle experience. A restaurant opened with the tower in 1962 and was designed to give guests a place to eat while overlooking the city. Over the years, the restaurant has changed names, seating arrangements, and menu styles to match new trends and renovations. Despite these updates, the basic idea has stayed the same. Visitors can order food or drinks and spend extended time at the top, rather than just stopping briefly to look out the windows. For many people, the combination of a meal and a wide city view defines the visit.

It has the world’s first and only revolving glass floor

Image: Morgan Petroski

A major renovation in 2018 introduced The Loupe, a rotating glass floor in the observation area. The platform moves slowly, allowing visitors to stand in one place while the view changes. Through the clear panels, people can look straight down at streets, buildings, and open spaces below. This is the only revolving glass floor of its kind in the world. The addition shows how the Space Needle continues to update its visitor experience while keeping its original structure intact.

Monkey's Eyebrow, Kentucky

Image: Jonny Belvedere

A name like "Monkey's Eyebrow" begs an explanation. One assumes there is a very particular story behind it. This is an unincorporated community in Ballard County, rural Kentucky, and the origin of its name is disputed. One of the theories suggests that, when seen from the air or on a map, the landscape in Ballard County looks like a monkey’s head, and this community has formed where the eyebrow would be .

Kentucky is, after all, no stranger to towns with odd names. Some of them include Rabbit Hash, Bachelor’s Rest, Sparta, and Oddiville itself.

Whynot, North Carolina

Yet another unincorporated community with an unusual name is Whynot, from Randolph County, North Carolina. Founded in the 18th century, the name was originally spelled separately: "Why Not."

The legend holds that, undecided about what name to pick for the town, the residents started throwing at one another "Why not this?" and "Why not that?" Until one bored resident said: "Why not name the town ‘Why Not’ and let's go home?" Joke or not, that ended up being the official name for the land. Today the community has an estimated 100 inhabitants.

Fries, Virginia

One would expect a big monument of golden fries to be erected in some square within Fries, Virginia. But you would be misled to imagine that. When pronounced correctly, this town’s name rhymes with "breeze." Situated on the New River in Grayson County, Virginia, Fries boasts beautiful natural landscapes, and visitors are encouraged to bike, hike or horse ride around the unspoiled countryside.

The town was named after a prominent cotton mill owner and businessman, Francis Henry Fries. Fries holds music festivals annually and has a strong bluegrass and country music culture.

Canadian, Texas

Canadian, Texas is not, in fact, Canadian. Founded in 1887, it is home to around 2,400 residents from the north of Texas, in Hemphill County. It was named after the Canadian River that flows one mile north. The river is a tributary of the Arkansas River, and it was named so in the 1820s when Canadian traders were spotted camping in its borders.

Here is a piece of trivia that you would never guess: The beginning and the end of the movie Cast Away (2000), with Tom Hanks, which occur in Texas, were filmed in Canadian and nearby.

Truth or Consequences, New Mexico

A city with a name that sounds like a threat, Truth or Consequences, New Mexico, is within Sierra County and has a population of a little over 6,000. It is sometimes shortened to "T or C."

The place wasn’t always called this.

Originally, it was named Hot Springs, after the springs it was built over, belonging to the Artesian Basin. However, in 1950, the NBC Radio quiz show called "Truth or Consequences" declared that the 10th anniversary of the program would be recorded in the first town that changed its name to that of the show. Thus, Hot Springs officially became Truth or Consequences to gain the honor, and the show’s host visited the former Hot Springs yearly for half a century after that.

Dinosaur, Colorado

Dinosaur is a small town in Moffat County, Colorado, that was once called "Artesia." However, in the 1960s, it was decided to rename it to attract tourists who were traveling to see the Dinosaur National Monument, east of the town. The park contains over 800 archeological sites and unique fossils and was proclaimed a National Monument in 1915 by Woodrow Wilson.

Dinosaurs did once roam the golden fields under the Blue Mountain Range where Dinosaur sits. Beyond the visit of paleontology fans, the town prides itself on boasting stunning natural views and wildlife that includes deer, elk, and antelope.

Okay, Oklahoma

Those who named this Oklahoma town "Okay" weren’t just trying to be funny. Okay, OK had several other names throughout history, including Coretta, Falls City, and Rex. The current one was adopted in 1919. Oklahoma Auto Manufacturing Company had a factory nearby, makers of the "O.K. Trucks." The official postal designation was changed in its honor.

The community had been established in 1806 on the east bank of the Verdigris River and had soon become a trading post for many visitors in the area, which allowed the settlement to grow.

Uncertain, Texas

Image: Scott Graham

Imagine the complications of filling out a form indicating that the name of your city is "Uncertain." This probably has happened to several residents, and it is closely related to the origin story of the town’s name.

It is said that, when applying for township, the residents hadn’t yet agreed on a name for the place. They tried to explain this by writing "uncertain" in the form’s blank space for the town name, hoping to resolve it in the future. But the township was eventually granted and the place came to officially be called Uncertain.

Uncertain is located in eastern Texas very near to the border with Louisiana. It sits near the Big Cypress Bayou and the banks of Caddo Lake.

Cut and Shoot, Texas

The town of Cut and Shoot, Texas, got its unusual name from a confrontation that occurred in July 1912. A local church, meant to be shared by various denominations, became the center of conflict when an Apostolic preacher was invited to hold a meeting. The community split into two sides, those for and against the preacher's appearance, and both arrived armed to enforce their stance.

During the argument, a frightened eight-year-old boy exclaimed, "I'm going to cut around the corner and shoot through the bushes!". The conflict was resolved peacefully that day, but a trial unfolded between the two leading families. When the judge asked the name of the community, someone suggested calling it the place of the "cutting and shooting scrape." Residents eventually took a liking to this term and adopted it.

Coward, South Carolina

Image: Yohan Marion

"Coward" sounds like an accusation, but it is also the name of a town in Florence County, South Carolina, with a population of just over 700. One would expect its name to derive from some story of dishonor and shame, but Coward is instead just a surname .

It is unclear and disputed whether the town was named after Capt. Solomon Coward, who owned most of the land, Col. Asbury Coward, a Confederate veteran, or John Wilson Coward, a member of the "Committee of 50." However, the rural farming community was called that many years before it was incorporated in 1963.

Seattle Underground City

Did you know the remnants of Seattle's original streets are still accessible? Beneath the bustling streets of modern-day Seattle lies the Underground City , a network of subterranean passageways that formed the ground level in the 1800s.

By the end of the 19th century, after the Great Seattle Fire, it was decided to rebuild the city at a higher elevation to combat frequent flooding . So, these original streets, sidewalks, and storefronts were buried, and with it, much of their history.

Guided tours take people through tunnels and ladders and retell real and eerie stories about the history of the Underground City.

This stunning subterranean retreat was built entirely by hand. Tucked under the sun-scorched landscape of Fresno, California, lie the Underground Gardens of Baldassare Forestiere . They are the life’s work of Baldassare Forestiere, a Sicilian immigrant who started digging in the early 1900s to escape the Central Valley's oppressive heat.

Over 40 years, drawing inspiration from ancient Roman catacombs , Forestiere carved an elaborate network of underground rooms, passageways, grottoes, and courtyards that span 10 acres.

A unique masterpiece, the gardens are open with guided tours that lead guests through beautifully designed spaces featuring skylights, arches, and alcoves. This oasis also boasts an array of fruit trees, including citrus, figs, and olives.

Colorful and breathtaking, the Ruby Falls is a geological wonder located inside Lookout Mountain near Chattanooga, Tennessee.

Hidden over 1,000 feet below the mountain's surface, this waterfall cascades 145 feet into a pool , making it one of the tallest underground waterfalls open to the public.

Visitors enter the mountain and descend via elevator. Then, they walk through stunning cave formations such as stalactites, stalagmites, and flowstone. At the waterfall chamber, multicolored lights –powered by renewable energy– illuminate the falls. Lantern-lit tours are also offered as a chance to visit the marvel with a different charm.

Arched tunnels of tranquil, sacred vaults lie beneath the Green-Wood Cemetery in Brooklyn, New York. Built in the mid-19th century, these catacombs were designed as a prestigious resting place for the city’s elite , prominent families.

While the catacombs are typically closed to the public, special events are sometimes organized to welcome visitors, such as art expositions, guided history tours, and candlelit tours seasoned with live music and storytelling.

Outside, where the sun does reach, await the serene landscapes and remarkable monuments of the cemetery, which is itself a National Historic Landmark .

The Mammoth Cave National Park is home to the longest cave system in the world . Located in central Kentucky, it extends over 420 miles of explored passages and many more likely undiscovered. Enormous chambers, underground rivers, a labyrinth of tunnels, and gypsum crystal formations can all be found at this site.

The park has been declared a UNESCO World Heritage Site and an International Biosphere Reserve. It also includes over 52,000 acres of protected land on the surface, renowned for its lush forests and diverse wildlife.

A large bat colony lives in the Carlsbad Caverns National Park in New Mexico, but that’s not its only charm. The park boasts over 100 caves, with its centerpiece being the immense Carlsbad Cavern.

The cavern includes the Big Room, one of the largest underground chambers in North America, spanning 8.2 acres. Visitors can descend via an emblematic natural entrance or by elevator, dropping 750 feet underground. Stalactite formations like the Giant Dome, the Hall of the White Giant, and the Chandelier are some of the caves' breathtaking highlights.

The Indian Echo Caverns, which have been open to the public since the early 1920s, are carved into the limestone of the Appalachian Mountains. Located near Hummelstown, Pennsylvania, this site gets its name from the echoes heard within the cavern’s chambers , which were once believed to be mystical by Native American people in the area.

Unique, immersive sections of the caverns have names like the "Crystal Palace," the "Echo Room," and the "Wedding Room," where, yes, real weddings are sometimes held!

Wind Cave National Park

Image: Francesco Ungaro

Wind Cave National Park, located in the Black Hills of South Dakota, is one of the world’s largest caves, but that’s not what it’s most famous for. One signature sight here is the boxwork formation , a rare lattice-like pattern formed by calcite deposits.

The cave system stretches for over 140 miles, though much of it remains unexplored. Popular tours take guests through captivating features like the "Ribbon Room" and the "Crystal Palace."

Why is Wind Cave called that? Mainly due to the "wind" phenomenon that occurs at its entrance. The cave's air pressure causes the entrance to draw in or expel air, depending on atmospheric conditions.
