Santa Fe, New Mexico

We’ll start with one of the most logical sisterhoods on this list: Since the capital city of New Mexico shares a name with the Spanish city of Santa Fe (full name "Santa Fe de La Vega"), it seems only reasonable for them to become sister cities—a relationship that was established in 1983.

Santa Fe was one of the first sister cities to the American city, and their bond remains strong. Both cities engage in various ways, whether through true cultural exchanges, economic insights, or tourism opportunities.

New York City, New York

Since New York City is probably the most famous American city in the world, it stands to reason that "The City That Never Sleeps" has many sister cities around the globe. We could have chosen from a long list of truly outstanding cities like London and Budapest, but we ultimately decided to showcase Tokyo. After all, both NYC and the Japanese capital share a buzzing and energetic atmosphere, filled with dazzling lights and exciting opportunities.

Interestingly, many of New York City’s boroughs have sister locations of their own. For instance, Brooklyn is the sister borough of Lambeth, a neighborhood located in southern London. Not only that, Manhattan is related to the Seocho district in Seoul, South Korea, while the municipality of Ulcinj in Montenegro is a sister to Staten Island.

Los Angeles, California

As a cultural hub and "the Entertainment Capital of the world," Los Angeles has several noteworthy siblings. In fact, it is one of the American cities with the most related cities, with 25 sisters as of 2024.

The city of Eilat, Israel, has the distinction of being Los Angeles’ first sister city, established in 1959. That same year, "The City of Angels" also became sister cities with Nagoya, Japan. Other notable sister cities of L.A. include Berlin, the capital of Germany, as well as Mexico City and Bordeaux, France.

San Francisco, California

As we are sure you know, San Francisco was built on a monastery founded by Spanish explorers in the 18th century, and it is from this early settlement that the city gets its name. In that sense, it stands to reason that the "Golden Gate City" shares a relationship with one of the most prominent cities in Spain.

While San Francisco is a sister city to 17 other locations (including Osaka, Japan, and Sydney, Australia), Barcelona is its only Spanish sister city. The relationship was established in 2010, and in 2018, Barcelona was honored alongside all of San Francisco's sister cities with a signpost in Hallidie Plaza.

Austin, Texas

Who could be a better sister city to the capital of our largest Southern state than someone from the "Land Down Under"? Since 1983, Austin, Texas, has been a sister city to Adelaide, one of the most prominent southern cities in Australia.

Remarkably, these cities share a number of amazing qualities: they are both filled with lush green scenery from their many parks, and they are crossed by equally beautiful rivers. Not only that, they are both music lovers: Adelaide is the first Australian city to be declared a UNESCO City of Music, while Austin is globally known as "the live music capital of the world."

Boring, Oregon

The town of Boring, Oregon , surely has had some tough luck: after all, would you like to visit a town with that name? The truth is that there’s nothing dull about this town; it was built in a former lava field (a rather exciting landscape, if we do say so ourselves) and named after William Harrison Boring, an early resident who helped build the town.

In any case, Boring’s rather unusual name has landed this town with kindred spirits. Since 2012, this town has been part of a group known as the "Trinity of Tedium." Alongside the village of Dull, Scotland, and the community of Bland, Australia, Boring has proven again and again that friends can be found in the most unusual of places.

Hackettstown, New Jersey

This is the only town on this list that shares an (almost) identical name with its sister. Hackettstown, New Jersey , is famous for being the headquarters of the beloved Mars corporation, which caters to the "sweet teeth" of many Americans. It was named after Samuel Hackett, an early settler of the area who helped build the community.

In 2011, this New Jersey town declared Hacketstown, Ireland, as its sister city. In case you are not familiar with this small Irish town, here’s a fun fact that might make you fall in love with it: Hacketstown was once the home of William Presley, an ancestor of the King of Rock 'n' Roll himself.

Boston, Massachusetts

In 1959, the city of Kyoto, Japan, became Boston’s first sister city . When you think about it, this relationship makes perfect sense: both cities are known as cultural and economic hubs and have strong and independent identities. According to the city of Boston’s official website, both of these metropolises share "strong neighborhood identities."

Throughout the decades, Boston and Kyoto have hosted several events, including annual exchange programs for high school students. Not only that, Kyoto gifted the Boston Children's Museum a "Japan House" in a display of kinship that is still warmly remembered by the capital city of Massachusetts.

Seattle, Washington

You might be familiar with a traditional Irish song called "Galway Bay." It has been covered by iconic American artists like Johnny Cash and Bing Crosby. This lovely tune is particularly famous among Irish Americans and speaks about nostalgia and the longing to gaze upon Ireland’s breathtaking shores. In that sense, should you suddenly feel overwhelmed by the powerful message of this song, we can offer you the next best option in America: Galway’s very own sister city, the wonderful Seattle .

Seattle and Galway became sisters in 1986, and two corresponding bronze markers were placed in each city to mark the distance between them. Many cultural events and exchanges are organized by the Seattle Galway Sister City Association, which helps build the relationship between these two wonderful cities.

Washington, D.C.

Our capital city is considered by many to be the personification of American democracy. After all, it houses both the White House and the Capitol Building and is named after the Father of our Country. Bearing that in mind, can you think of a better sister city for Washington D.C., than the birthplace of democracy?

Washington D.C., became the sister city of Athens, Greece, in 2000. Curiously, Athens is also the sister city to another American city, although perhaps less famously: the Greek capital city also maintains a relationship with the identically named city of Athens, Georgia.

A Presidential curse

For almost 140 years, U.S. presidents elected in years ending in zero died while in office. It happened to William Henry Harrison (elected in 1840, died in 1841), Abraham Lincoln (elected in 1860, died in 1865), James A. Garfield (elected in 1880, died in 1881), William McKinley (re-elected in 1900, died in 1901), Warren G. Harding (elected in 1920, died in 1923), Franklin D. Roosevelt (elected to a third term in 1940 and a fourth in 1944, died in 1945), and John F. Kennedy (elected in 1960, died in 1963). Ronald Reagan, elected in 1980, broke the curse by surviving an assassination attempt.

Mark Twain and Halley’s Comet

In the year Mark Twain was born, 1835, Halley’s Comet passed by Earth. The great writer famously predicted he’d "go out with it" as well . Indeed, he passed away in 1910, the next time the comet appeared.

3

Jefferson and Adams

A patriotic yet somber coincidence, indeed. John Adams and Thomas Jefferson, the second and third U.S. presidents, both died on July 4, 1826 —exactly 50 years after the signing of the Declaration of Independence.

4

Hoover Dam’s first and last casualties

The construction of the Hoover Dam was a long and difficult process, claiming over 100 lives. The first person to die was J.G. Tierney , and the last recorded death was his son , Patrick Tierney.

5

Lincoln and Kennedy

Abraham Lincoln and John F. Kennedy were elected 100 years apart (1860 and 1960). Both suffered fatal head wounds and were succeeded by presidents named Johnson. Their assassins each had three names: John Wilkes Booth and Lee Harvey Oswald. Both were assassinated on a Friday while sitting next to their wives at the time that it happened.

Charles Francis Coghlan’s last journey

Actor Charles Francis Coghlan died in Texas in 1899. But his casket was lost at sea during a hurricane. Eight years later, his coffin washed ashore near his birthplace in Prince Edward Island, Canada, more than 3,000 miles away.

7

The Titanic coincidence

A few years before the Titanic sank, Morgan Robertson wrote a short book called Futility , about a massive "unsinkable" ship called the Titan that hit an iceberg and sank. The tale describes a ship with a similar size and a similar lack of lifeboats to the famous vessel.

8

Dennis the Menace

Two comic strips featuring a character named Dennis the Menace debuted in British and American outlets, respectively, on March 12, 1961—only a few hours apart. However, the two creators did not know each other and had no idea of the other’s work.

9

Jim Lewis and Jim Springer

Identical twin brothers separated at birth , Jim Lewis and Jim Springer, were reunited at age 39 and discovered many coincidences: both married women named Linda , divorced, and then remarried women named Betty. Both had dogs named Toy and drove the same model of car. Both grew up with an adopted brother named Larry and had sons whom they named James Allan.

Disney magic

A soon-to-be-married couple, Alex and Donna , were looking through old photos to include in their wedding video. They found one photo of Donna posing on a childhood trip to Disney World in 1980. And in the background, they spotted Alex being pushed in a stroller by his father.

Moped meets taxi, twice

In 1975, 17-year-old Erskine Lawrence Ebbin was struck by a taxi in Bermuda while riding his moped. A year later, his brother Neville , also 17 at the time, was riding the same moped when he was struck by the same taxi —with the same passenger—on the same street.

12

Lightning strike survivor

Being hit by lightning is an extremely rare occurrence. Park ranger Roy Sullivan was struck not once, but seven times between 1942 and 1977 —and survived them all. The strikes hit him in a fire tower, in his truck, in his yard, while patrolling, and more. His unusual record earned him the nickname "Human Lightning Rod."

Columbus discovered America

Image: Hector John Periquin

Although this isn't strictly about the United States, it does concern our continent. It's often said that Columbus "discovered" the Americas in 1492, but that's not precisely true. He wasn't even the first outsider to arrive! The Vikings, led by Leif Erikson, reached North America around the year 1000 AD, almost 500 years before Columbus. And, of course, the continent was already inhabited long before any European explorers arrived.

George Washington had wooden teeth

One of the most famous historical myths is that George Washington, the first US president, had wooden teeth. While it's true that he struggled with dental problems and used several prosthetic devices made from various materials, none of his teeth were actually made of wood.

The US Declaration of Independence was signed on July 4, 1776

Image: Glen Carrie

Every 4th of July, the country turns into a party. And it's no wonder, since we're honoring Independence Day! Perhaps because of the date of this holiday, many people believe that the US Declaration of Independence was actually signed on July 4, 1776. In reality, the key event on that day was the Continental Congress voting to adopt the Declaration of Independence. Most delegates actually signed the document later, on August 2, 1776, in Philadelphia.

America became fully independent in 1776

Image: The New York Public Library

On July 4, 1776, the American colonies declared their independence from Great Britain by adopting the Declaration of Independence. However, the Revolutionary War continued for several more years. It wasn't until the war ended in 1783, with the signing of the Treaty of Paris, that the United States' independence was officially recognized.

Cowboys wore Stetson hats

Image: Brice Cooper

Although Stetson hats are now inseparable from the cowboy image, the reality of the 19th century was pretty different. People in the Wild West sported a variety of styles: while some did wear wide-brimmed hats similar to Stetsons, these were not the most common, and many other types were also popular.

6

Paul Revere rode alone

Image: Pixabay

Paul Revere's name became a symbol of American courage and determination. His midnight ride on April 18, 1775, was undoubtedly heroic, but some details have been distorted over time. While many think he shouted "The British are coming!", historians suggest he likely said something closer to "The regulars are coming", given the dates. And contrary to popular belief, Revere didn't ride alone; he was part of a group of riders working together to warn the colonial militia.

George Washington chopped down a cherry tree

Image: Jeffrey Clayton

The story of George Washington chopping down a cherry tree is one of the most famous tales in American history. However, it's actually a myth, created by one of Washington's early biographers to highlight one of his defining characteristics: honesty. Although there is no reliable historical evidence to support this famous anecdote, there is plenty of proof of the courage and honesty of the Father of His Country.

8

Al Capone was jailed for his violent crimes

Image: Ashim D’Silva

Al Capone was one of the most infamous gangsters in history. Although his life was filled with criminal activity, it wasn't his violent acts that put him in jail, as there wasn't enough evidence to convict him. Instead, authorities used tax evasion charges, and he was finally imprisoned for that reason in 1931.

Prohibition made drinking illegal everywhere

Image: Drew Beamer

Many people assume that drinking alcohol was completely illegal during Prohibition. In reality, the 18th Amendment and the Volstead Act (1920–1933) banned the manufacture, sale, and transportation of alcohol, but not the act of drinking itself!

The Founding Fathers as a unified group

Image: J. Amill Santiago

Many believe the Founding Fathers worked as a unified group, sharing a single vision without disagreement. But history tends to be a little more complex. While they collaborated and worked hard to establish the United States, they held diverse ideas and visions for the nation, and some even became rivals. Yet, despite their differences, they successfully laid the foundations for the first large-scale modern republic.
