A Presidential curse

For almost 140 years, U.S. presidents elected in years ending in zero died while in office. It happened to William Henry Harrison (elected in 1840, died in 1841), Abraham Lincoln (elected in 1860, died in 1865), James A. Garfield (elected in 1880, died in 1881), William McKinley (re-elected in 1900, died in 1901), Warren G. Harding (elected in 1920, died in 1923), Franklin D. Roosevelt (elected to a third term in 1940 and a fourth in 1944, died in 1945), and John F. Kennedy (elected in 1960, died in 1963). Ronald Reagan, elected in 1980, broke the curse by surviving an assassination attempt.

Mark Twain and Halley’s Comet

In the year Mark Twain was born, 1835, Halley’s Comet passed by Earth. The great writer famously predicted he’d "go out with it" as well . Indeed, he passed away in 1910, the next time the comet appeared.

Jefferson and Adams

A patriotic yet somber coincidence, indeed. John Adams and Thomas Jefferson, the second and third U.S. presidents, both died on July 4, 1826 —exactly 50 years after the signing of the Declaration of Independence.

Hoover Dam’s first and last casualties

The construction of the Hoover Dam was a long and difficult process, claiming over 100 lives. The first person to die was J.G. Tierney , and the last recorded death was his son , Patrick Tierney.

5

Lincoln and Kennedy

Abraham Lincoln and John F. Kennedy were elected 100 years apart (1860 and 1960). Both suffered fatal head wounds and were succeeded by presidents named Johnson. Their assassins each had three names: John Wilkes Booth and Lee Harvey Oswald. Both were assassinated on a Friday while sitting next to their wives at the time that it happened.

Charles Francis Coghlan’s last journey

Actor Charles Francis Coghlan died in Texas in 1899. But his casket was lost at sea during a hurricane. Eight years later, his coffin washed ashore near his birthplace in Prince Edward Island, Canada, more than 3,000 miles away.

7

The Titanic coincidence

A few years before the Titanic sank, Morgan Robertson wrote a short book called Futility , about a massive "unsinkable" ship called the Titan that hit an iceberg and sank. The tale describes a ship with a similar size and a similar lack of lifeboats to the famous vessel.

8

Dennis the Menace

Two comic strips featuring a character named Dennis the Menace debuted in British and American outlets, respectively, on March 12, 1961—only a few hours apart. However, the two creators did not know each other and had no idea of the other’s work.

Jim Lewis and Jim Springer

Identical twin brothers separated at birth , Jim Lewis and Jim Springer, were reunited at age 39 and discovered many coincidences: both married women named Linda , divorced, and then remarried women named Betty. Both had dogs named Toy and drove the same model of car. Both grew up with an adopted brother named Larry and had sons whom they named James Allan.

Disney magic

A soon-to-be-married couple, Alex and Donna , were looking through old photos to include in their wedding video. They found one photo of Donna posing on a childhood trip to Disney World in 1980. And in the background, they spotted Alex being pushed in a stroller by his father.

Moped meets taxi, twice

In 1975, 17-year-old Erskine Lawrence Ebbin was struck by a taxi in Bermuda while riding his moped. A year later, his brother Neville , also 17 at the time, was riding the same moped when he was struck by the same taxi —with the same passenger—on the same street.

12

Lightning strike survivor

Being hit by lightning is an extremely rare occurrence. Park ranger Roy Sullivan was struck not once, but seven times between 1942 and 1977 —and survived them all. The strikes hit him in a fire tower, in his truck, in his yard, while patrolling, and more. His unusual record earned him the nickname "Human Lightning Rod."

Seattle: The Seattle Underground

People usually visit Seattle for the seafood, waterfront views, coffee culture, and the famous Space Needle. But underneath the busy sidewalks lies part of the city most tourists never realize exists. Beneath Pioneer Square sits the Seattle Underground, a network of old streets and storefronts buried below modern Seattle.

This area dates back to the Great Seattle Fire of 1889, which destroyed much of downtown. City leaders decided to rebuild the streets one story higher to improve drainage problems that had plagued the city for years. For a while, businesses operated below street level, but eventually this lower level was abandoned. Today, guided tours take visitors through the underground passageways and old sidewalks and mix ghost stories and old city legends with the real story below Emerald City.

2

Chicago: The Chicago River

Between deep-dish pizza, Wrigley Field, jazz clubs, and the towering skyscrapers, few cities feel more American than Chicago. It’s also home to the magical Chicago River, which, in 1900, actually flowed backwards.

Back in the late 1800s, Chicago faced a dangerous problem. The river carried sewage and industrial waste into Lake Michigan, the same lake supplying the city’s drinking water. Disease outbreaks of typhoid and cholera became increasingly serious, and engineers realized something drastic had to happen. In 1900, after years of planning and digging canals, they built a series of canals and locks, like the prominent Chicago Sanitary and Ship Canal, connecting the Chicago River to the Des Plaines River, forcing the water to flow toward the Mississippi River watershed. That way, they reversed the river’s direction so the contaminated water would flow away from the lake instead of into it. The natural flow was forever altered, but it remains central to city life, especially during St. Patrick’s Day when, according to tradition, it’s dyed bright green every year.

New York City: NYPL hidden apartment

Yellow taxies, Central Park, Broadway shows, and nonstop energy have made New York City feel magical. The Big Apple hides many secrets, and the apartment inside the New York Public Library Main Branch is just one of them.

In 1910, the library superintendent, John Fedeler, and his family moved into a private eight-room apartment tucked inside the library. This was so that someone would always be available to maintain the huge building. With bedrooms, a kitchen, and a living area, a full home is hidden behind doors that most visitors passed by. The family lived there until 1941, when the space was converted into offices and storage areas. However, the library still offers tours where visitors can learn about its history.

Portland: Mill Ends Park

When you think of Portland, you may think of Washington Park or Forest Park. But if you pay close attention, you can also visit Mill Ends Park. At just two feet across, it holds the Guinness World Record as the world’s smallest park.

At first glance, it looks more like a flowerpot than a public landmark, but the story goes back to 1948, when journalist Dick Fagan noticed an empty hole that had been meant for a light pole. Tired of staring at it from his office window, he planted flowers there and jokingly claimed that, since it was so small, it was a park for leprechauns. The joke took on a life of its own, and in 1976, it was dedicated on St. Patrick's Day. Today, it’s a must-do for travelers going through Portland, and locals continue treating it with surprising seriousness.

5

Houston: The Beer Can House

Everything is bigger in Texas, and Houston is no exception. If you’ve been there, you’ve probably visited NASA, the Museum District, and tried a local barbecue joint. But you’ve probably missed a quirky house hidden among the neighborhoods. Located at 222 Malone St, sits the Beer Can House. The name is self-explanatory, since it’s a house covered with beer cans.

In 1968, John Milkovish decided he was tired of painting and maintaining the exterior of his property. Instead, he began flattening beer cans and attaching them to the house. What started as a hobby slowly turned into a full-blown obsession involving more than 50,000 cans. The house went from being a neighborhood curiosity to a roadside attraction to finally being a protected local landmark in 2001. In 2010, Time magazine even ranked it as one of America's top 50 roadside attractions. True to his Texan blood, John Milkovish built something big.

San Francisco: The Wave Organ

No trip to San Francisco is complete without taking the cable car or a picture at the Golden Gate. But tucked away near the Marina District is an attraction many tourists completely miss. The Wave Organ is a gigantic acoustic sculpture that turns ocean waves into music.

Completed in 1986 by artist Peter Richards, t he installation consists of a series of pipes extending into the bay. As tides rise and waves move through the pipes, they create eerie sounds ranging from soft bubbling to deep echoes. Richards was inspired by recordings of artist Bill Fontana, made of sounds coming from a vent pipe of a floating concrete dock in Sydney, Australia. In 1980, he received a grant from the National Endowment for the Arts and tested the first prototypes during the 1981 New Music Festival. Five years later, he completed this sonic sculpture that runs entirely on nature.

Los Angeles: La Brea Tar Pits

Los Angeles is all about Hollywood, palm trees, and the beaches. But it’s also home to one of the world’s most important prehistoric sites. The bubbling black pools at La Brea Tar Pits have been trapping animals for tens of thousands of years.

Long before Los Angeles was the city it is today, natural asphalt constantly came up from underground. Mammoths, saber-toothed cats, dire wolves, and other Ice Age animals became trapped there, preserving their skeletons remarkably well. Scientists began excavating fossils in the early 1900s, and discoveries continue to this day. The fossils recovered from the site are countless. Visitors can explore the museum for $18 and watch active excavations while surrounded by modern office buildings and traffic.

Seattle: The Giant Shoe Museum

Seattle already has its share of unusual attractions, especially around Pike Place Market, where fishmongers toss salmon through the air, and crowds line up for fresh pastries. But the Giant Shoe Museum, located there, is even stranger. A single exhibit wall dedicated to oversized footwear , the museum works like an arcade peep show. Visitors drop coins into viewing slots to reveal displays featuring enormous boots, giant clown shoes, and other gigantic footwear.

The museum was founded in 1997 by Danny Eskenazi after he became obsessed with his grandfather’s missing item: the shoe of Robert Wadlow, the tallest man in history. He even offered $1,000 to anyone who could find that Wadlow shoe. Sadly, the shoe remains lost, but his obsession led to the discovery of other shoes worn by Wadlow and more footwear that is now displayed in the museum.

Boston: Great Molasses Flood Site

Boston's most popular spots blend colonial and Revolutionary War history with vibrant neighborhoods that feature top attractions like the Freedom Trail, Fenway Park, and the Boston Public Garden. But it’s also home to the remains of a disaster.

In 1919, Boston experienced the Great Molasses Flood. A massive molasses storage tank burst in the North End neighborhood, unleashing more than two million gallons of syrup into the streets. After 21 people lost their lives, the disaster led to stricter construction safety regulations across the country, and the tank was never rebuilt. Today, visitors can still walk through the neighborhood where it happened. There’s no giant syrup wave anymore, thankfully, but plaques and local tours continue telling the story.

Lake Havasu City: The London Bridge

Driving through Lake Havasu City in Arizona, you expect desert landscapes, boating, and blazing summer heat. You probably don’t expect to stumble across a famous bridge from England, especially not the original London Bridge itself.

In 1831, John Rennie designed and opened the London Bridge spanning the River Thames. By the 1960s, the bridge started sinking under the weight of modern cars and traffic. Robert P. McCulloch, founder of Lake Havasu City, saw this as an opportunity and, in 1968, he purchased the bridge for $2.4 million. The bridge was dismantled and reconstructed in the Arizona desert, and completed in 1971. What once connected two sides of London now links mainland Lake Havasu City with Pittsburgh Point that visitors and locals enjoy every day.

Atlanta: The Center for Puppetry Arts

Atlanta is often associated with Southern cooking, a busy airport, and its important role in the Civil Rights Movement. But tucked inside the city is also the Center for Puppetry Arts, which houses the world’s largest collection of Jim Henson’s original Muppets.

The center opened in 1978, when puppeteer Vincent Anthony transformed a former elementary school into a home for puppet arts. From the very beginning, the project had a special connection to Jim Henson himself. He and Kermit the Frog helped inaugurate the center, and over the years, Henson became one of its biggest supporters. The center expanded significantly between 2007 and 2015, adding the permanent Jim Henson Collection and the impressive Worlds of Puppetry Museum. Unlike many museums, this place is hands-on. Guests can watch live performances, explore exhibits from puppet traditions, and revisit characters that shaped generations of childhood memories.

A mountaintop with a maintenance plan

Image: Sebastian Enriqu

Each year, around two million visitors make their way to see the monument. But keeping the presidential faces looking sharp takes serious work. Park Service staff actually rappel down the mountain to inspect for cracks. They use silicone sealant to block out moisture and keep the granite from breaking apart in the cold. This isn’t a quick job, it’s a regular, careful operation. The mountain's top sits 5,725 feet above sea level, so it’s not for the faint of heart.

One historian’s tourism dream

Image: Engin Yapici

Back in 1923, South Dakota historian Doane Robinson had an idea to attract visitors to the Black Hills. Now, what was his original plan? Carve Western legends like Buffalo Bill and Native American leaders into the rock. The vision then shifted to feature US presidents for broader national appeal.

President Calvin Coolidge helped land the funding, even during tough economic times. The carving began in 1927 and stretched on until 1941. Sculptor Gutzon Borglum died before finishing, and his son Lincoln carried the torch to completion.

Four presidents, four chapters

Image: Jeromey Balderrama

Each face on the mountain stands for a key period in our nation’s story. Can you imagine what they are?

Washington symbolizes the birth of the country, while Jefferson represents growth and expansion. Lincoln stands for unity and the preservation of the nation during the Civil War. Roosevelt brought development and the rise of the US on the world stage. Together, they tell a chronological story in stone. The idea was to highlight leadership through the ages, not just popular figures.

A presidential switch

Image: Andrew Ling

Originally, Thomas Jefferson was supposed to be on Washington’s left. But during the carving, the rock proved too unstable. So they scrapped the partially finished face and started over, this time on the right side.

It was a major do-over that cost time and money, a lot of it! But ultimately, it worked out for the best, structurally speaking. Today, most visitors never realize Jefferson had a false start.

Dynamite and a dream

Image: Takefreebies

It’s easy to forget that Mount Rushmore wasn’t sculpted with tiny chisels: It was blasted into shape. Most of the work was done with dynamite, followed by finer detailing with jackhammers and drills.

From 1927 to 1941, about 400 workers shaped the mountain. Amazingly, no lives were lost during the entire project. Many of the workers were former miners, used to rough terrain and heavy tools. It wasn’t easy, but it was efficient.

6

The presidents were supposed to have torsos

Image: Thomas Fields

The original vision for the monument wasn’t just heads, it included bodies from the waist up! Imagine that! Like many grand ideas, it ran into budget troubles. Funding dried up, and with time running out, the project was scaled back.

What we see today is actually an unfinished version of Borglum’s full plan. Still, the heads alone have become iconic. Imagine how much more impressive it would’ve been with shoulders and coats.

Secrets behind Lincoln’s head

Image: Rosanne Rapata

There’s a hidden room carved into the mountain, did you know that? Called the Hall of Records, it was Borglum’s idea to store important American documents and artifacts.

While the grand plans for a museum inside the mountain were never fully realized, a titanium vault was placed there. It contains copies of key US documents, including the Constitution and the Declaration of Independence. Located behind Lincoln’s head, it’s not open to the public. Still, it adds an air of mystery to the site. It makes you wanna visit, right?

Step off the beaten path

Most visitors snap their photos from the Grand View Terrace, and it’s lovely. But for those willing to take a short walk, the President’s Trail offers even better views.

This loop takes you closer to the monument and into nature. You might spot local wildlife like mountain goats or deer along the way. The trail includes about 422 stairs, so make sure you’re wearing comfy shoes. It’s a quieter, more personal way to experience the monument.

Entablature

Image: Tommy Bond

Gutzon Borglum didn’t just want Mount Rushmore to be a visual tribute, he wanted it to tell the story of America, too. His idea was to chisel a brief summary history, covering events from 1776 to 1906, right into the rock face.

This massive engraving, called "Entablature," was to be etched into an 80-by-120-foot depiction of the Louisiana Purchase. President Calvin Coolidge even agreed to write it, but when Borglum edited Coolidge’s draft without permission, the president was so annoyed he refused to try again. Despite the grand vision, the project was eventually scrapped, partly because the lettering wouldn’t have been visible from a distance, and partly because the budget ran dry.

10

Don’t expect a fifth face anytime soon

Image: Ronda Darby

Over the years, people have suggested adding more figures to the mountain. Names like Susan B. Anthony, FDR, JFK, Reagan, Obama, and Trump have all come up. But the National Park Service has said a firm "no." Structurally, there’s just no safe place to add another carving. Plus, the monument is considered complete in its message. So, while the debate pops up now and then, don’t hold your breath. The original four are here to stay.
