The Situation Room

Tucked into the West Wing basement, the Situation Room is the White House crisis headquarters . President Kennedy ordered it built in 1961, after the Bay of Pigs fiasco left him frustrated by slow, jumbled intelligence. It's a complex of rooms, staffed around the clock. The famous 2011 photo of Obama's team watching the bin Laden raid was taken there. A $50 million, year-long gut renovation finished in 2023; the previous one was in 2007.

The PEOC

Deep beneath the East Wing sat the PEOC, short for Presidential Emergency Operations Center . FDR had the bomb shelter built in 1942, disguised as an office wing, and Truman's early-1950s rebuild expanded it. Military staff ran it around the clock.

Vice President Cheney was rushed inside on 9/11, and Trump sheltered there in May 2020. The East Wing was demolished in 2025, and they are digging a bigger, secret replacement.

The Map Room

Before the Situation Room, there was the Map Room, on the residence's ground floor. During World War II, FDR used it to follow the fighting, with maps, pins, and secret messages handled by Army and Navy officers. It was off-limits to nearly everyone.

The Truman rebuild of 1949–52 paneled it, and it was last redecorated in 1994. Today it's a sitting room that still shows off a few maps.

The Family Theater

This 42-seat movie theater began in 1942 as a cloakroom nicknamed the "Hat Box," when the White House needed a screening room. Eisenhower added the plush front-row armchairs, Reagan's team redid it in 1982–83, and Laura Bush gave it "movie-palace red" in 2005.

Carter reportedly watched about 480 films there in four years, and Kennedy's last movie there was reportedly the James Bond flick From Russia With Love , in the fall of 1963. The theater was demolished in October 2025 for the new ballroom.

The Press Briefing Room

You've seen it on TV, but the secret is underneath. In 1933, FDR got an indoor pool here to ease his polio pain. Nixon, who preferred bowling, covered it in 1970 and built the press room on top , reportedly insisting it could be restored. The pool still sits under the floor.

Renamed for James Brady in 2000, the room was renovated and reopened in 2007; the press secretary holds court there.

6

The Bowling Alley

The first White House bowling alley arrived in 1947, a two-lane birthday gift for Truman from Missouri friends. Staffers formed a league in 1950, but the lanes were moved out in 1955. Then, in 1969, friends funded a one-lane alley for Nixon , hidden beneath the North Portico driveway. He and Pat bowled there often, and his best reported score was 232. It's still down there, closed to the public.

7

The Solarium

Perched on the third floor over the South Portico, the Solarium is a sunny family hangout . Pre-AC, President Taft had a rough sleeping porch up there for hot summer nights, and the real room came in 1927, when Coolidge added the third floor. Grace Coolidge called it her "Sky Parlor."

After World War II, it became more of a family rec room. Mamie Eisenhower hosted card games there, while Ike grilled steaks outside.

8

The Lincoln Bedroom

Despite the name, Lincoln never slept in that bed. In the southeast corner of the second floor, the room was his office and Cabinet room, and he signed the Emancipation Proclamation there on January 1, 1863. Mary Todd Lincoln bought the famous rosewood bed in 1861, but the space became a bedroom only in the Truman years.

Today it's a guest room, famously used for overnight guests during the Clinton years.

9

The Medical Clinic

It's less "hospital" and more "doctor's office." A small exam room sits on the ground floor, near the Map Room, backed by the White House Medical Unit: about two dozen military doctors, nurses and aides, with offices in the next-door Eisenhower building. They're on call around the clock for the president, the VP, staff, and even tourists . Full-time presidential doctors date to McKinley, and a formal 24-hour rule came in the 1990s.

10

The Treaty Room

On the second floor, the Treaty Room was the Cabinet Room from 1865 to 1902. On August 12, 1898, President McKinley witnessed the peace protocol ending the Spanish-American War being signed there. Jackie Kennedy's restoration gave it its name in the early 1960s , and JFK signed the 1963 nuclear test ban treaty there. Obama used it as a main office. Today it's a presidential study, with drapes modeled on Lincoln-era designs.

11

The Flower Shop

Yes, the White House has its own flower shop, tucked beneath the North Portico. A Chief Floral Designer and a staff of florists create arrangements for the public and private rooms, matched to each room's color scheme . First Lady Jacqueline Kennedy established the Office of the White House Florist in the early 1960s.

Flowers have been a White House habit far longer, though: a conservatory supplied blooms through the 1800s.

Measuring

This is a difference most Americans are aware of: most countries use the metric system rather than U.S. customary units, and most use Celsius instead of Fahrenheit. Countries such as the UK and Canada still use some imperial units in everyday life, but they mainly use the metric system. Another measure that confuses foreigners is the particular way ingredients are measured in American recipes, which often use cups, tablespoons, and teaspoons rather than measurements by weight.

Fun fact: The only other countries that use the Imperial system officially are Liberia and Myanmar.

2

Sales tax

Do you find having to calculate sales taxes annoying? That’s a unique American experience. In the majority of the world, the price you see is the price you pay , because it has the sales tax already added.

Why is it different in America? Sales taxes vary across states , so retailers find it easier to showcase the base price and then calculate the total at checkout.

3

Cutlery use

Many Americans abroad are surprised by the realization that not everyone uses a knife and fork in the same way they do . In fact, no one else does. While most Americans have learned the American style —also called the zig-zag or fork switching method— that involves using the fork in the left hand for cutting and then changing it to the right to pick up the food, European and Latin American countries don’t do this . It might seem like a small difference, but it completely changes the way you eat.

4

Iced drinks

Do other countries not have ice? They do, but they don’t necessarily assume everyone will want it. While serving water and other beverages with ice is customary in America, in many other countries, you need to request it —even during the hottest of summers.

But even if you get ice, many times you will need to specify the amount : the same drink that would be filled with ice cubes in America might come to you with just two or three cubes elsewhere.

5

Date formatting

The U.S. is not completely alone on this one, but there’s a difference big enough to be worth mentioning. The standardized way of recording the date in America is month-day-year , a convention also followed by some Caribbean and Asian countries. But in the rest of the Western world, the conventional format is day-month-year , which can lead to confusion for Americans. In most Asian countries , the most commonly used format is year-month-day .

6

The word ‘American’

In the English language, ‘American’ is the only way to refer to people with U.S. citizenship . Other words, such as ‘Usian’ or ‘Unitedstatian’ have been proposed, but never stuck. This is why many Americans are surprised when other countries —Latin American countries in particular— use ‘American’ for anyone in the American continent , or continents, another big difference. In most European and Latin American countries, there is a different word for U.S. citizens, such as the Spanish ‘estadounidense’ or the Portuguese ‘estadunidense’ .

7

Moving out at 18 years old

This one is not so black and white, but more like a general tendency. Compared with most of Europe, Latin America, and Asia, Americans give serious consideration to the possibility of moving out after high school. Not everyone does, and not everyone can afford it, but it's fairly common.

In other countries, young adults generally move out if their job or education requires it , but they tend to stay at home a few more years if they can.

8

Driving a car as a teenager

America is quite car-centric , especially if you live outside of the big cities. While not everyone can afford to have a personal car —even a second-hand one—, it is common for 16 and 17-year-olds to legally drive their parents’ car, or save for their own.

In the rest of the world, the chances of high schoolers driving themselves to school are much lower, as most countries don’t allow underage kids to get a driving license .

9

Solo cups

Do plastic cups exist outside of the U.S.? They do, but they are not as iconic or as widely used as Solo cups, introduced in the 1970s as a disposable but sturdy cup for parties and events. Many foreigners visiting America are surprised when they realize that solo cups are a real thing , and not something that just happens in movies.

10

Filing taxes

Taxes in the U.S. are not that different from taxes in other countries, except for how they are filed . During tax filing season, thousands of Americans direct their efforts to ensure they have properly reported their income and that their return will match the IRS’s data.

In other parts of the world, however, the one responsible for calculating and filing taxes is the government , while citizens merely corroborate that everything is in order.

Dundas Castle, Roscoe, New York

Image: Annie Spratt

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.

3

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.

5

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?

6

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.

7

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.

9

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.

10

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.
