Dundas Castle, Roscoe, New York

Also known as Craig-e-Clair, this castle was built by Ralph Dundas in the early 20th century. It is an architectural marvel of stone and copper.

Dundas died before the castle was completed, and his wife was reportedly committed to a sanitarium shortly after. Consequently, no member of the Dundas family ever actually lived in the mansion. This has led to the "Ghost of Dundas Castle" legends, with locals claiming to see a woman in white wandering the unfinished halls, waiting for a housewarming party that never happened.

Rockwell House, Milledgeville, Georgia

Built in 1838, the Rockwell House is a stunning example of Federal-style architecture, but its beauty is shadowed by a dark past. It was originally built for Colonel Samuel Rockwell, a prominent lawyer.

Local lore whispers about the "Rockwell Ghost," believed to be a young girl who died during a yellow fever outbreak. However, the house’s most tangible secret lies in its survival; it has endured multiple fires and periods of extreme neglect. In recent years, it has become a focal point for preservationists who uncovered hidden structural reinforcements that suggest the house was built to be an impenetrable fortress of its era.

Elda Castle, Ossining, New York

If the name David Abercrombie sounds familiar, it’s because he co-founded the clothing company Abercrombie & Fitch . But in the 1920s, he also built this granite castle, named Elda (an acronym of his children’s names), as a secluded retreat.

The castle features a network of spiral staircases and open-air porches designed to blend the indoors with the rugged wild. Its abandonment, however, is a sheer tragedy. After the family moved out, the castle was used as a research facility and later fell victim to vandals. Legend has it that a fire in the 1940s was started by squatters, leaving behind a charred stone husk that resembles a medieval ruin more than a 20th-century home.

Mongo's Castle, Memphis, Tennessee

A stark contrast to the classical mansions of the South, Mongo’s Castle was the passion project of Mongo Bebe, a man who built his home out of scrap stone, Ashlar blocks, and found materials.

The house is a maze of folk-art eccentricity. The builder intended it to be a community center and a symbol of African-American heritage and self-reliance. It stands today as a decaying puzzle, with many neighbors still unsure of the structural logic behind its towering, uneven walls.

Bannerman's Castle, Pollepel Island, New York

Rising from the Hudson River, this castle was never intended to be a home; it was a giant advertisement and warehouse for Francis Bannerman VI’s military surplus empire.

In 1920, 200 tons of gunpowder and shells exploded in the castle’s powder house, blowing out a significant portion of the walls. The ground is still considered unstable due to the remnants of military munitions, and the inscriptions on the walls are actually warnings and advertisements for the Bannerman business. Do you dare visit this mansion?

Castle Mont Rouge, Rougemont, North Carolina

Image: Florian Delée

This whimsical, onion-domed castle looks like it belongs in the Russian countryside rather than the North Carolina woods. It was designed by sculptor Robert Mihaly, but he ended up abandoning the project in the early 2000s following a personal tragedy and financial hurdles.

The castle remains an "empty sculpture," filled with intricate marble work and unfinished turrets. The bizarre architectural fusion lacks a standard floor plan, making it nearly impossible to convert into a functional residence without destroying its artistic integrity.

Ha Ha Tonka Castle, Camdenton, Missouri

Robert Snyder, a wealthy Kansas City businessman, began building this European-style castle in 1905. He wanted a retreat that overlooked the breathtaking Ha Ha Tonka Spring.

Yet, Snyder never got to see his dream finished; he was killed in one of Missouri’s first recorded automobile accidents just a year after construction began. His sons finished the castle, but it was gutted by a fire in 1942. There’s a hidden network of caves beneath the castle, which were rumored to be used by outlaws and later as a natural "refrigerator" for the estate’s kitchen.

Carleton Island Villa, Cape Vincent, New York

This once-magnificent villa was built for William Wyckoff, who made a fortune with the Remington Typewriter Company.

The Secret: Wyckoff’s dream turned into a nightmare on the very first night he stayed in the house. He suffered a massive heart attack and died in his sleep. His wife had passed away a month prior, leaving the villa to a son who had no interest in it. The house has stood empty for over 70 years, its secret being the tragic "cursed" timing that prevented it from ever functioning as a family home.

Dicksonia Plantation, Lowndesboro, Alabama

Image: Theo Bickel

Dicksonia was a quintessential antebellum mansion, featuring the massive columns and wrap-around porches synonymous with the Old South.

Unlike many plantations that were destroyed during the Civil War, Dicksonia survived the conflict only to be destroyed by a mysterious fire in 1939. Its "ghost pillars," however, remained standing long after the wooden house burned away. These towering brick columns became a haunting landmark , representing the structural skeletons of a forgotten social order.

Wyndcliffe, Rhinebeck, New York

Image: Peter Herrmann

This house is the literal origin of the phrase "Keeping up with the Joneses." Though often referred to as a "Mystery Mansion" by urban explorers, this is the ruin of Wyndcliffe, the estate of Elizabeth Schermerhorn Jones.

Elizabeth’s mansion was so grand and intimidating that it prompted her neighbors—including the Astors—to build even larger homes to compete. The secret of Wyndcliffe is the psychological impact of its architecture; it was built to inspire envy, and its current state of absolute decay is a poetic commentary on the fleeting nature of social status.

The original plan included full-body figures

Image: Thomas Shockey

Mount Rushmore was supposed to be even more colossal than it already is. Sculptor Gutzon Borglum envisioned the four presidents carved from the waist up .

He even made plaster models showing Abraham Lincoln's coat folds and Teddy Roosevelt’s hand clutching his lapel. But as costs went up, Congress said: "heads only, please."

2

Charles Rushmore was just a curious New Yorker

Image: Maarten van den Heuvel

Back in 1925, when the mount was about to be carved into a monument, Charles Rushmore wrote a letter explaining why the peak bore his name. He recalled that in the 1880s he was a young New Yorker working in the area, and fell fond of that particular granite peak .

When he asked the locals about it, they informed him that it had no name, but that if he wished so, they would just start calling it Rushmore Peak, or Mount Rushmore, or the likes. Years later, that very name had been inscribed in the public domain to designate the peak.

Yes, there’s a hidden room behind Lincoln’s head

Image: Laura Nyhuis

Behind Abraham Lincoln’s hairline lies a hidden chamber, part of Borglum’s lofty idea for a "Hall of Records." This room was meant to house foundational American documents like the Constitution or the Declaration of Independence.

Instead of that, in 1998, a titanium box was placed inside, filled with copies of important documents and biographies, as a time capsule to preserve the treasure of knowledge for future generations.

4

Thomas Jefferson was moved

Image: Dave Baraloto

Jefferson was originally supposed to go to Washington’s right, but after 18 months of chiseling , the granite betrayed them. Cracks and flaws made the site unworkable.

Borglum made the painful decision to blast Jefferson’s half-formed face clean off and start anew on Washington’s left.

5

The mountain was almost a monument to western heroes

Image: Timberly Hawkins

Before presidents took over, the mountain was pitched as a giant tribute to the Wild West . South Dakota historian Doane Robinson wanted to see frontier legends like Lewis & Clark carved into the Black Hills.

But when Borglum came aboard, he had a grander (and more politically bankable) idea: four presidents to symbolize national unity and expansion.

6

A woman’s face was almost added

Image: Tom Fournier

In the 1930s, there was serious talk of honoring Susan B. Anthony alongside the Founding Fathers, as a nod to the women’s suffrage movement.

Borglum wasn’t opposed to the idea, but Congress quickly nixed it, stating that only U.S. presidents could be included.

7

The workers were mostly local miners and loggers

They were neither sculptors nor artists. Most of the workforce came from nearby Keystone, South Dakota: miners, loggers, and hard-up laborers looking for work during the Great Depression.

Borglum trained them himself. There were no safety harnesses, and yet, remarkably, no one died on the job.

8

Dynamite did 90% of the work

Image: Alexander Paramonov

To carve the faces of Washington, Jefferson, Roosevelt, and Lincoln, workers used carefully timed dynamite blasts to remove over 450,000 tons of rock. They got so precise, they could blast within inches of where the final surface would be.

The last details, like wrinkles, pupils, or Roosevelt’s glasses, were done with jackhammers and chisels.

9

The noses are disproportionate

Image: Dudubangbang Travel

Standing in front of the mountain, the faces seem alright. But that’s a trick of perspective. Each presidential nose is a whopping 20 feet long .

If the sculptures had included full bodies as planned, each figure would have stood 465 feet tall. That’s taller than the Statue of Liberty and most downtown skyscrapers.

10

Teddy Roosevelt was the most controversial pick

Image: Dudubangbang Travel

Washington, of course. Jefferson, made sense. Lincoln, sure. And Teddy? Some critics raised their eyebrows at Borglum’s fourth choice. Roosevelt had only recently passed away in 1919, and many questioned whether he'd stood the test of time.

But Borglum defended the decision Roosevelt’s role in breaking up monopolies, conserving national parks, and engineering the Panama Canal. Plus, Borglum had met him personally and was a fan.

11

It was supposed to have inscriptions

Image: Dan Pick

Borglum had grander plans than just four giant heads. He wanted to carve a massive inscription next to them, a timeline of America’s most important milestones , chiseled straight into the mountain. In time, the idea was scrapped for practical and aesthetic reasons.

12

The visionary died before completion

Image: Lisa Reichenstein

Gutzon Borglum, the visionary behind it all, didn’t live to see his masterpiece finished. He died in March 1941, just as the construction was reaching its end. His son, Lincoln Borglum (yes, named after that Lincoln), took over the project.

Still, with WWII drawing resources elsewhere, funding was slashed, and Lincoln had to wrap things up quickly . Some features, like Lincoln’s ear, were never fully detailed.

1

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 (1840), Abraham Lincoln (1860), James A. Garfield (1880), William McKinley (1900), Warren G. Harding (1920), Franklin D. Roosevelt (1940), and John F. Kennedy in 1960 . Ronald Reagan, elected in 1980 , broke the curse by surviving an assassination attempt.

2

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.

3

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.

4

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.

6

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.

9

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.

10

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.

11

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."
