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

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

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 Big Apple: New York City

Image: Nik Shuliahin

Everybody knows "The Big Apple" refers to New York— the city that never sleeps . But why, exactly? Is it because there’s a worm (the subway) underneath it? Or is it a metaphor for something we strive for?

2

The Big Easy: New Orleans

It sure feels easy to stroll through New Orleans, a city known for its laid-back atmosphere and rich cultural energy, where jazz bands can spontaneously form on any corner and lively public celebrations are always just around the bend. But what’s the story behind its nickname?

Motor City: Detroit

The most populous city in Michigan, the nickname "Motor City" certainly feels right for its bustling streets and large industrial background —but what exactly led to the adoption of this powerful nickname?

4

Sin City: Las Vegas

Image: Grant Cai

We all know the famous adage: "What happens in Vegas, stays in Vegas." Given the city’s notorious nightlife and gambling scene , it’s understandable—you might prefer to forget how you lost all your savings on a slot machine. But is that the only reason it earned its infamous nickname?

5

The Windy City: Chicago

Image: Ozzie Stern

Situated on the shores of Lake Michigan, Chicago's nickname might seem to stem from its exposure to harsh weather —but sometimes, the obvious answer isn’t the correct one. Is it really the weather, or is something stranger at play?

The Mile High City: Denver

Is Denver really a "Mile High" city because of its geographical proximity to the towering Rockies, or is it just a nod to its ever-expanding skyline? Keep reading to find out!

And now, the answers:

7

The Big Apple: Horse-racing origins

Image: Taylor Sondgeroth

The nickname originated in the 1920s as horse-racing slang , where "The Big Apple" informally referred to New York’s prize racetracks. Jazz musicians later popularized it, and a 1970s tourism campaign ultimately cemented it as a symbol of the city’s cultural and financial prominence.

8

The Big Easy: Chill and jazz

Image: Robson Hatsukami Morgan

If you followed our line of thought—you were right! This nickname emerged from the city's reputation for its relaxed lifestyle and vibrant jazz scene . While there are many theories about who first used the term—and whether it was originally meant to be derogatory—one thing is certain: all New Orleanians agree it 100% reflects the city’s unique blend of music, culture, and laissez-faire attitude.

9

Motor City: Infinite assembly lines

Image: Austrian National Library

Detroit earned its nickname as the birthplace of the American auto industry. Henry Ford’s revolutionary assembly line and the rise of car manufacturing giants cemented the city’s status as the global automotive capital of the 20th century. In fact, it remains home to the headquarters of America’s largest auto manufacturers—General Motors, Ford, and Chrysler.

10

Sin City: Prohibition defiance

Image: Jakub Dziubak

For a city founded by religious missionaries, "Sin City" is certainly an ironic nickname. In truth, its origins trace back to the construction of the nearby Hoover Dam in the 1930s. Thousands of workers flocked to the city in search of lodging and—presumably—entertainment. This led to the rapid rise of casinos and a thriving underground alcohol industry that—during Prohibition—was as profitable as it was illegal.

11

The Windy City: Long-winded speeches

Image: Kristina Paparo

While many assume it refers to Chicago’s weather, the nickname was actually coined by journalists mocking the boastful speeches of local politicians as they aggressively promoted the city as the ideal location for the World’s Fair. The term was meant to highlight the "hot air" of their rhetoric rather than the city's literal windiness.

12

The Mile High City: A matter of altitude

Image: Bill Griepenstroh

Denver sits exactly 5,280 feet — one mile — above sea level , earning its nickname, the "Mile High City," quite literally. Its natural elevation, combined with stunning Rocky Mountain views, makes it truly unique. Even more interesting, Denver’s altitude leads to some unusual effects: golf balls can travel up to 10% farther than at sea level, and alcohol tends to hit harder since high altitudes reduce the body's ability to process it efficiently.

1

It happens every 10 years

The U.S. Census is required by Article 1, Section 2 of the Constitution and takes place every decade, ending in "0," such as 2000, 2010, and 2020 . The first census was conducted in 1790 under President George Washington.

This fixed schedule ensures consistency. Population changes over time, so a regular count allows the government to fairly adjust representation and resources based on where people actually live.

2

It counts everyone living in the U.S.

The census aims to count every person residing in the country, not just citizens. This includes legal residents, undocumented immigrants, and people without permanent housing .

The key concept is "usual residence," meaning where a person lives most of the time. This approach provides a realistic snapshot of the population and ensures communities are represented accurately.

3

It determines seats in the House of Representatives

Census results are used to divide the 435 seats in the U.S. House of Representatives among the 50 states , a process known as apportionment.

States can gain or lose seats depending on population shifts. For example, after the 2020 census, Texas gained two seats, while states like California and New York lost one each due to slower growth.

4

It influences federal funding

Census data guide the distribution of hundreds of billions of dollars in federal funding each year, with estimates ranging from $675 billion to $1.5 trillion.

Programs for highways, hospitals, schools, and housing depend on population figures . Areas with higher populations typically receive more funding, making an accurate count financially important for communities.

5

Households receive census invitations

Every household in the United States receives an official census invitation , usually by mail. In 2020, more than 140 million housing units were included.

This system replaced earlier door-to-door counting methods. Using a national address database helps ensure broad coverage and makes it easier for people to respond on their own.

6

It can be completed online, by mail, or by phone

The modern census offers multiple ways to respond. In 2020, people could complete it online, by mailing back a paper form, or by phone .

Adding online responses marked a major shift. It reduced costs, improved convenience, and reflected how Americans increasingly move towards digital communication.

7

Census workers follow up in person

If households do not respond, trained census workers, called enumerators, visit homes in person to collect the information.

This step is essential because the census must count everyone, not just those who respond voluntarily . It helps reach people in rural areas, dense cities, and communities with lower response rates.

8

It asks basic demographic questions

The census form is intentionally short. In 202, it included about 10 questions covering age, sex, race, household relationships, and housing status.

The goal is to keep it simple. Shorter forms increase participation while still collecting the key data needed for representation, funding, decisions, and planning.

9

Responses are legally confidential

Federal law strictly protects census responses. Under Title 13 of the U.S. Code, personal data cannot be shared with law enforcement, immigration authorities, or other agencies .

Only anonymous, combined statistics are released. Census workers face severe penalties, including fines and prison, for revealing personal information.

10

Missing the census is technically against the law

Responding to the census is legally required. Federal law allows fines for refusing to answer or providing false information .

In practice, penalties are rarely enforced. The rule exists mainly to emphasize how important it is for everyone to be counted accurately.

11

The data helps draw voting districts

After the census determines how many representatives each state receives, the data is used to redraw congressional and state legislative districts .

This process, called redistricting, ensures districts reflect current population patterns. It supports the principle of equal representation, often described as "one person, one vote."

12

Results are released over time

Census results are published in stages. Basic population counts come first, allowing Congress to complete apportionment.

More detailed demographic data follows months later. This gradual release ensures accuracy while protecting privacy , sometimes using advanced techniques like statistical noise to safeguard identities.
