The Feejee Mermaid

In 1842, showman P. T. Barnum unveiled a marvel: a preserved "mermaid" supposedly from the South Seas . Crowds lined up to see the half-fish, half-woman curiosity.

The truth was stranger still. It was the upper body of a monkey sewn onto a fish tail and covered in papier-mâché.

5

The Great Moon Hoax

Readers of The New York Sun in 1835 were astonished by reports claiming that scientists had spotted bat-like people and crystal palaces on the Moon through a powerful new telescope.

The Crop Circles Craze

When perfect circles began appearing overnight in wheat fields , people talked about UFO landings. The shapes seemed too precise to have been made by human hands.

The Drake’s Plate of Brass

In 1936, a shiny brass plate found in California seemed to confirm that explorer Sir Francis Drake had landed there in 1579. Historians called it a priceless relic.

Paul, very much alive, later joked about it. The bizarre theory became a lasting pop-culture phenomenon.

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

Image: Clem Geiss

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

Image: Nitrogel

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

Image: Denny Müller

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

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.
