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.

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.

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.

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

Image: Hannah McBride

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

Image: Tama66

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.

Death Cap (Amanita phalloides)

Image: Rémi Müller

The first mushroom in our list is also the most toxic in the world. It was originally found only in Europe until imported trees transported it to America and everywhere else. Over time, Death Caps adapted to native trees, enhancing their ability to proliferate.

These unassuming-looking mushrooms have tinted green caps, white stems, white gills, and a white partial veil . They grow around oak, beech, chestnut, birches, hornbeams, spruce, and pine. Death Caps fruit in summer through fall underneath these trees, and are responsible for more than 90% of all mushroom poisonings and fatalities worldwide.

2

Destroying Angel (Amanita bisporigera)

Image: Sai Kiran Belana

Another member of the Amanita species with an ominous name, the Destroying Angel is the number one toxic mushroom in North America and is extremely widespread. Its all-white cap and stem often lead to mistaken identity with button mushrooms and meadow mushrooms.

The Destroying Angel grows from a white volva egg-like sac, features gills, and has a tall, slender stem . Its stems typically range from 3 to 8 inches in length, making it stand out in the forest like an all-white apparition. None of the common lookalikes grow this tall.

3

Funeral Bell (Galerina marginata)

Image: Lucas van Oort

The Funeral Bell appears somewhat harmless, and most poisonings are from mistaken identification. This "little brown mushroom" closely resembles several edible species, including the widespread Sheathed Woodtuft.

Funeral Bells grow on rotting wood, preferring conifer species, though they are not limited to them. They are found across North America, Asia, Australia, and Europe. This mushroom features a cone-shaped brown cap, light brown gills, and a tan to rusty-brown stem . A key distinguishing feature is a membranous ring around the upper part of the stem.

4

Pholiotina rugosa (previously Conocybe filaris)

Image: Kadri Võsumäe

A common lawn mushroom prevalent in the Pacific Northwest, this deadly fungus contains amatoxins, which destroy the liver and can cause death. Pholiotina rugosa is slender, petite, and rather innocent-looking. The cap is smooth, brown, and conical, with rusty brown gills underneath . The stem is also brown and features a distinctive, prominent ring around the middle—a key identification feature.

This deadly mushroom isn’t picky about habitat. It will grow on the lawn, soil, compost, and woodchips. P. rugosa is easily transported to new locations through woodchip and compost deliveries and adapts to new environments with little trouble.

5

Fool’s Funnel (Clitocybe rivulosa)

Image: Hoejin Iwai

Fool’s Funnel grows across North America in meadows, lawns, and other grassy areas from summer through autumn. It often grows in fairy rings, and accidental consumption by children or pets is a significant concern. These toxic mushrooms are small, white, and benign-looking . The caps are white and funnel-shaped, with crowded white gills underneath. Fool’s Funnel stems are also white and lack distinctive markings.

While this fungus rarely causes death, its ingestion will cause severe pain. This mushroom contains high levels of muscarine which acts as a nerve agent when ingested.

6

Deadly Webcap (Cortinarius rubellus)

Image: Markus Spiske

Another mushroom with a foreboding name, the Deadly Webcap, is found in coniferous and mixed forests across North America. It contains a toxin called orellanine, which can cause severe kidney failure when ingested.

The Deadly Webcap bears a close resemblance to edible species like the Chanterelle , making it especially dangerous for foragers.

7

False Morel (Gyromitra esculenta)

Image: jaStra

As the name implies, the False Morel is a toxic mushroom closely resembling the highly prized Morel mushroom . It contains a toxin called gyromitrin, which can cause severe gastrointestinal symptoms, seizures, and even death if ingested in large quantities.

There are multiple species of False Morels, and current evidence suggests that many are safe to eat, while Gyromitra esculenta should still be foraged with caution. Many people consume this mushroom, but only with proper preparation. This is not a mushroom you can simply sauté and eat; proper preparation is necessary to remove most of the toxins, making it "safe.

8

Common Conecap (Pholiotina rugosa)

Image: Oliver Fetter

This small brown mushroom contains the same deadly amatoxins found in the Death Cap and Destroying Angel. It is commonly found on or around wood mulch , particularly in landscaped areas. Its tendency to appear in yards makes it especially dangerous. Ingesting even a small amount of this toxic fungus can result in severe illness or death.

9

Amanita Muscaria

Image: Егор Камелев

Probably the most recognizable mushroom shape in the world is Amanita muscaria . Its stereotypical toadstool stands out in the woods thanks to its bright red cap with white spots and a white stem . These mushrooms are considered toxic and can cause pain but are unlikely to cause death.

Few mushrooms share the same scarlet hue that makes them so visible in green and brown underbrush. The white bumps on the cap also create a distinct, eye-catching pattern.

10

Green-Spored Parasol

Image: Timothy Dykes

Known as "the vomiter" for the effects it can have on anyone who consumes it, the Green-Spored Parasol has the same general shape as the Death Cap and Destroying Angel. Its stem is tall and thin, with a skirt that sits just under the cap . This cap ranges from rounded downward to wide and flat, depending on the mushroom’s age.

The symptoms from its ingestion range from extreme stomach irritation to bloody diarrhea, as well as the aforementioned vomiting. Therefore, caution is advised.
