From Lincoln to Lizzie Borden: The 14 most haunted spots in America

Image: Sandy Flowers

We know—it’s one thing to watch a scary movie hidden behind a giant bag of popcorn, and a very different thing to step into a dark, allegedly haunted house while an eerie, chilly breeze brushes your neck. Here, we’ve made a list of houses, hotels, and mansions in America with the spookiest claims of paranormal activity . Which one would you be brave enough to visit?

1
The Whaley House in San Diego, California

Image: Ivan Borinschi

The Whaley House is one of the few homes officially deemed "haunted" by the US government. Visitors report footsteps echoing in empty hallways, cold spots that won’t go away, and spectral figures on the stairs. How did it come to this? Built in 1857 by Thomas Whaley, the house stands on the site of former gallows. Whaley installed San Diego’s first brick house, which included a courtroom, general store, and theater space.

Unfortunately, Whaley’s daughter died by suicide in the house, and other family members passed away under the same roof. Accumulated tragedies and a spooky old house were enough to turn this eerie spot into a museum.

2
The Roosevelt Hotel in Los Angeles, California

Image: pure julia

Built in 1927, this glamorous hotel hosted the very first Academy Awards. Stars like Clark Gable, Charlie Chaplin, and Marilyn Monroe were among its esteemed guests. But, according to recent visitors, Monroe never really checked out.

She is said to appear in a mirror that once hung in her poolside suite. Guests have reported seeing the reflection of a blonde woman behind them, only to turn around and find no one there. How would you react?

3
The White House in Washington, D.C.

Image: Suzy Brooks

Did you expect to find America’s most powerful address on this list? As it turns out, presidents, first ladies, and staff have all reported eerie encounters over the years, with Abraham Lincoln’s presence as a recurring theme.

Queen Wilhelmina of the Netherlands allegedly fainted after seeing his ghost, and Eleanor Roosevelt claimed to feel his presence. Even Winston Churchill and Ronald Reagan contributed to the stories of a mysterious presence in the Lincoln Bedroom. Reagan famously reported that his dog, Rex, refused to enter the room.

4
The Winchester Mystery House in San Jose, California

Image: Brett Wharton

When it comes to haunted mansions, Sara Winchester’s old Victorian-Gothic house will always sit in the podium.

After her wealthy husband and several family members died within months of each other , Sara began commissioning the construction of this puzzling house, which remained under continuous construction for 38 years. Naturally, it’s a bit of a labyrinth.

With staircases that lead nowhere, séance rooms, and flickers of shadowy figures here and there, the house stands as a monument to grief—and to ghosts.

5
The Villisca Axe Murder House in Villisca, Iowa

Image: Kevin Schmid

It might look like a quaint white farmhouse, but in 1912, it was the site of one of America’s most brutal unsolved murders. The Moore family and two guests were killed with an axe while they slept. There were no witnesses, and no real explanation was ever found.

Today, the house remains frozen in time, restored to its 1912 condition. Creaking floors, oil lamps, and a whole lot of uneasy silence.

6
Lizzie Borden House in Fall River, Massachusetts

Image: Bee Felten-Leidel

You know the rhyme: "Lizzie Borden took an axe…" This New England house was the scene of one of America’s most infamous double murders in 1892. Lizzie was acquitted, but many believe she was responsible for the deaths of her father and stepmother, who were found dead under violent and suspicious circumstances.

Today, the house operates as a B&B for the brave and the curious. Guests have reported hearing footsteps, whispers, and even muffled cries coming from empty rooms. Some even choose to sleep in the very bedroom where Abby Borden met her tragic end.

7
The Lemp Mansion in St. Louis, Missouri

Image: Dhruv vishwakarma

Once home to the wealthy Lemp brewing dynasty, the mansion witnessed four family suicides between 1904 and 1949. That’s enough to make anyone who steps inside feel a bit… uncomfortable.

The family was cursed by misfortune: mental illness, failed fortunes, and mysterious deaths. Guests now report heavy footsteps in empty halls, strange knocking, and even ghostly apparitions—especially in the downstairs bathroom, where one Lemp took his own life. Today, it operates as a restaurant and inn.

8
Franklin Castle in Cleveland, Ohio

Image: Rob Potter

This Victorian mansion looks like it was designed to be haunted. Built in 1881 by Hannes Tiedemann, the home witnessed the deaths of several of his children and his wife within a short period.

Since then, tales of secret passageways, Nazi spies, and ghostly weeping have become forever attached to the castle. Owners have come and gone , but as the locals expected, none have chosen to stay.

9
The Sallie House in Atchison, Kansas

Image: Caroline Rogers

What began as a doctor’s residence in the 1800s took a dark turn when a young girl named Sallie allegedly died on the operating table . Her ghost, people say, began tormenting a later male resident, scratching, shoving, and even burning him.

Paranormal teams have confirmed that lights flicker, toys move on their own, and male visitors, especially, report sudden feelings of hostility.

10
The House of Death in New York, New York

Image: With Paul

Behind the brownstone elegance of 14 West 10th Street in Greenwich Village lies one of NYC’s darkest secrets: over 20 reported deaths have occurred there.

Mark Twain was its most famous tenant , living there briefly in 1900. He once recounted a story about a floating log inside the house, but insisted that a rodent must have been responsible. Paranormal enthusiasts, however, refuse to believe his explanation and now claim that Twain’s ghost also haunts the house.

11
The Joshua Ward House in Salem, Massachusetts

Image: Blake Cheek

This Georgian brick home sits under a dark curse in Salem. Its original land once held the jail of Sheriff George Corwin, infamous for torturing accused witches during the 1692 Salem Witch Trials. Known as the "Strangler," Corwin died of a heart attack at age 30 and was secretly buried in the basement.

Today’s residents and visitors report strangled sensations, cold drafts, and photographic anomalies—including a famous 1980s photo that appears to show a ghostly woman dressed in black with no eyes.

12
LaLaurie Mansion in New Orleans, Louisiana

Image: Alain Pierre-Lys

Few stories are darker than that of Madame Delphine LaLaurie, a socialite whose elegant French Quarter mansion concealed an appalling secret. In 1834, a fire revealed a hidden attic where enslaved individuals had been cruelly confined under horrific conditions.

LaLaurie fled to Paris, but the ghost stories remained. Visitors claim to hear moans and phantom footsteps and to see shadowy figures. Actor Nicolas Cage once purchased the property but quickly sold it, claiming bad luck followed him.

13
The Bell Witch Cabin in Adams, Tennessee

Image: Alex Vinogradov

This cabin marks the site of one of America’s oldest and most documented hauntings: that of the Bell Witch . This ghost received the nickname for haunting the Bell family in the 1800s. For years, the family endured a spirit that scratched walls, pulled hair, and even spoke in full sentences.

Legend has it that the entity killed patriarch John Bell. To this day, the rebuilt cabin and nearby cave remain popular destinations for ghost hunters.

14
The Riddle House in West Palm Beach, Florida

Image: Braden Wagner

Originally a funeral home (already a chilling start, right?), the Riddle House was later converted into a private residence. The story goes that it became haunted after an employee named Joseph hanged himself in the attic.

The house was eventually moved to Yesteryear Village to be preserved as a historical site, but it seems the ghosts made the trip too.

The secrets of the greenback

Dollar bills are green for this reason

Image: Pepi Stojanovski

The U.S. dollar is one of the most powerful and recognizable currencies in the world, but its physical form is unique for many other reasons . From its composition to its symbols, dollar bills and coins are carefully designed to combine history, security, and convenience. Let’s explore our national currency!

1
What are bills made of?

Image: Viacheslav Bublyk

Unlike other currencies, dollar bills are not made of paper or plastic. U.S. dollar bills are made from a special fabric blend composed of 75% cotton and 25% linen. This mix makes the bills extremely durable and resistant, and they can be folded about 4000 times before tearing.

2
What bills are valid?

Image: U. S. Government, The Bureau of Engraving and Printing, Public domain, via Wikimedia Commons

Any U.S. dollar bill that was legally printed is valid, no matter how old, as American currency does not have an expiration date. While some bills might not be accepted by businesses of foreign exchange services due to their condition or if they are a discontinued version of the bill, the bills themselves are still valid, and American banks will accept them, though they might take them out of circulation.

3
American leaders

Image: Lukasz Radziejewski

Five bills have a depiction of an American president. The exceptions are the $10 bill, with Alexander Hamilton on the front, and the $100 bill, with Benjamin Franklin. The $1 bill, depicting George Washington, is extremely symbolic: several elements are repeated 13 times as a nod to the thirteen colonies, and it showcases the Bald Eagle and the Eye of Providence as a sign of God watching over America.

4
A change in size

Did you know that dollar bills used to be so big that they were nicknamed "horse blankets"? Original dollar bills were 7.4 × 3.1 inches. In 1929, the Treasury Department reduced the size of bills to 6.14 × 2.61 inches to reduce production costs and materials. Old bills, though still valid, are worth much more as collector items.

5
Uniformity

Image: Avinash Kumar

Besides their value and design, all dollar bills have the same size (6.14 × 2.61 inches), color, and weight (1 gram) , which sets American currency apart from other countries where bills of different values are differentiated by size, color, or both. Why doesn’t the U.S. implement differences among bills? The cost of adapting vending machines, bank drawers, and ATMs to new bill sizes would cost billions of dollars.

6
Hard to copy

Originally, dollars were not green, but black. As time passed, green ink was favored, as it was cheap and did not fade as much as black. The new color also prevented people from using black-and-white cameras to create counterfeit money. Currently, dollar bills are predominantly green, but newer versions also include extra colors, such as pink, orange, or purple.

7
A $100,000 bill?

Image: The original uploader was Durova at English Wikipedia., Public domain, via Wikimedia Commons

Have you ever seen a $500 or 1,000 dollar bill? What about a $100,000? Up until 1945, the U.S. Treasury printed $500, $1,000, $5,000, $10,000, and $100,000 notes , in addition to the values currently in use. These higher-value notes were mainly intended for bank and government use, but were sought by criminals as they made it easier to hide large amounts of money. Even though they were officially discontinued in 1969, these notes are still valid, though rare, and they have a high worth as collector's items.

8
No numbers

Image: Quilia

Unlike bills, American coins have different sizes and colors related to their value. Originally, gold, silver, and copper were used for coins, but modern coins are made of copper, zinc, or nickel. Besides their size and design, the value of each coin is printed in letters, not in numbers , alongside depictions of American presidents.

9
Liberty for all (the coins)

Image: Money Knack

By law, all American coins must include six specific details : the word ‘Liberty’, the name of our country, the national motto "In God We Trust", the oldest American motto "E Pluribus Unum", the value of the coin, and the year. Each coin also includes a mint mark that shows where it was made: "P" for Philadelphia, "D" for Denver, "S" for San Francisco, and "W" for West Point.

10
A global currency

Image: Logan Voss

The American dollar is one of the most powerful currencies in the world, acting as a backbone for international trade and finances. It is estimated that two-thirds of the physical dollars in circulation are outside American territory. Besides the U.S. and its territories, eight sovereign nations have the U.S. dollar as their official currency, with several more accepting it as legal tender.
