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

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.

"One small step" vs. "Man, that may have been a small one…"

Neil Armstrong stepped onto the lunar surface with his carefully planned line: "That is one small step for a man , one giant leap for mankind." Pete Conrad from Apollo 12 decided to have some fun with that.

Conrad was short, and he had bet a reporter five hundred dollars that he could say whatever he wanted when he stepped down. This is the line he went for, as documented in NASA transcripts: "Whoopie! Man, that may have been a small one for Neil, but that is a long one for me ."

2

Apollo 12 and the lightning strike that tried to end everything

Apollo 12 was struck by lightning not once but twice, only 36 seconds after launch. The electrical surge wiped out telemetry in Mission Control.

The flight looked doomed until flight controller John Aaron said the now legendary instruction: "Try SCE to Aux." Conrad responded with, "What the hell is that?" because almost no one remembered what SCE meant.

Luckily, Alan Bean understood what to do. He flipped the switch, the instruments rebooted, and Apollo 12 kept flying.

3

Apollo 13 was just as dramatic as the movie showed

The explosion of an oxygen tank in Apollo 13’s service module really did turn the mission into a race against time. The line "Houston, we have a problem" is Hollywood’s adaptation, however. The real line, spoken by Jack Swigert and repeated by Jim Lovell, was "Houston, we have had a problem."

Other real drama: the crew used the Lunar Module as a lifeboat, battled rising CO₂ levels, manually aligned the spacecraft using Earth’s horizon, and returned home with only a sliver of battery life left.

Apollo 16 astronauts drove a moon rover like teenagers with a new car

The lunar rover was a marvel: lightweight, foldable, and capable of reaching 13 to 18 km/h depending on conditions.

John Young and Charlie Duke from Apollo 16 were so thrilled with it that Mission Control had to repeatedly remind them not to drive too fast on uneven terrain.

Duke even recorded one of the wildest moments of the program when Young yelled, "Look at that… look at that!" as dust flew up behind them.

5

The dust that drove astronauts nuts

Moon dust is sharp, sticky, and electrostatically clingy. Astronauts from Apollo 11 onward complained that it smelled like burnt gunpowder and got everywhere. Harrison Schmitt from Apollo 17 suffered "lunar hay fever" after breathing dust tracked into the cabin.

NASA later became mildly obsessed with studying how dangerous that dust might be… and it turns out it is genuinely abrasive to suits and could be risky to lungs.

6

Apollo 11 and the computer that said "nope"

Just minutes before landing on July 20, 1969, the Apollo Guidance Computer flashed a "1202" program alarm. In non-NASA terms, the computer was overloaded and essentially panicking .

But guidance officer Steve Bales had trained for this exact situation and cleared the crew to proceed. Armstrong later said this call was one of the mission’s most decisive moments. So yes, the first Moon landing almost got canceled by a stressed-out computer.

7

The golf shot that echoed through history

On Apollo 14, Alan Shepard smuggled a makeshift golf club head along with two golf balls.

On the moon, he attached it to a sample collection tool and made the most famous swing in the Solar System. The ball truly did travel far, although probably not the "miles and miles" Shepard joked about. Still, it remains the only round of lunar golf ever played.

8

Apollo 15’s postal controversy

The Apollo 15 astronauts carried unauthorized stamped envelopes to sell to collectors later.

This became a scandal when the deal came to light. NASA was furious, the crew was reprimanded, and the agency tightened rules on what astronauts could take to space.

The event is fully documented and remains one of the strangest side stories of the program.

Twelve people walked on the moon

Between 1969 and 1972, exactly twelve astronauts walked on the lunar surface.

The list, in chronological order, is: Armstrong, Aldrin (Apollo 11), Conrad, Bean (Apollo 12), Shepard, Mitchell (Apollo 14), Scott, Irwin (Apollo 15), Young, Duke (Apollo 16), and Cernan and Schmitt (Apollo 17). Cernan remains the last human to have walked on the Moon.

10

The last moonwalk included a love letter

During Apollo 17, Gene Cernan traced his daughter’s initials TDC on the lunar dust.

As he said his farewell words on the Moon, he hoped the world would continue exploring. His last line: "We leave as we came and, God willing, as we shall return, with peace and hope for all mankind."
