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.

Manifest Destiny

(1840s – Westward Expansion)

Coined in 1845 by journalist John L. O’Sullivan, "Manifest Destiny" justified America’s push westward, claiming it was the nation’s divine right and duty. Though sometimes controversial, it shaped the national mindset and defined 19th-century American expansionism.

Talk turkey

(1800s – Rural America)

"Talking turkey" originally meant speaking plainly, especially during trade or bargaining sessions around Thanksgiving time. The phrase evolved from settlers' interactions with Native Americans and each other.

3

The whole nine yards

Image: Museums Victoria

(1940s – WWII era)

This phrase likely originated in World War II aviation. Fighter pilots reportedly gave "the whole nine yards" when they unloaded all their ammunition —about 27 feet of bullets. It now means going all out, and its roots in wartime tales made it a lasting piece of American lingo.

4

Cold turkey

Image: Andres Siimon

(1920s – Prohibition era)

"Cold turkey" first emerged in drug withdrawal circles during the 1920s, describing a sudden and complete stop, often painful and abrupt. It became more widespread during Prohibition, when people abruptly quit drinking.

5

Pull yourself up by your bootstraps

Image: Nathan Dumlao

(1930s – Great Depression)

Originally a sarcastic quip about doing the impossible, the phrase took on a new life during the Depression, urging Americans to self-rely and push through adversity. By WWII, it had become a proud motto for working-class Americans.

6

Loose lips sink ships

(1940s – WWII propaganda)

Created by the U.S. Office of War Information, this saying warned citizens and soldiers against careless talk that might aid enemy spies. It was one of the most effective propaganda slogans of WWII.

7

Duck and cover

Image: Stephen Cobb

(1950s – Cold War drills)

Coined in a 1951 civil defense film, this phrase taught schoolchildren to seek shelter from nuclear blasts. While its actual effectiveness was debatable, "duck and cover" captured the anxious era of nuclear tension. It’s since become shorthand for futile emergency preparedness.

8

Jump on the bandwagon

Image: Museums of History New South Wales

(19th century – American politics)

Originating in the 1848 campaign of circus showman Dan Rice, politicians literally used bandwagons to draw crowds. The term evolved as others "jumped on" to align with the popular cause. It now refers to any late but enthusiastic adoption of a trend.

9

Cut to the chase

(Hollywood – silent film era)

Early films often built up slowly, so impatient viewers and editors began saying, "cut to the chase" —the action scene. Now it means getting straight to the point.

10

Put a sock in it

(1920s – Gramophone era)

Before volume knobs, people muffled early gramophones by stuffing socks in the horn. The phrase quickly became slang for "be quiet."

The first toll

Image: Barry A

When the bridge first opened to cars, the toll was 50 cents each way, $1 for a round trip, and an additional 5-cent charge for cars carrying more than three passengers. While this may not seem like much today, that money was crucial in covering the construction costs. In today’s terms, the toll would be equivalent to about $11 .

The Half-Way-to-Hell Club

Building this massive suspension bridge was no easy task, and the story of the "Half-Way-to-Hell Club" members proves just how dangerous it was. These 19 workers were on the job when they slipped and fell from the bridge . But in the midst of their fall, something saved them : a safety net placed under the bridge, an ingenious and innovative safety measure for the 1930s.

A different picture

Image: Leo_Visions

While it's hard to imagine the Golden Gate Bridge without its iconic "International Orange" color, the original plan was actually quite different. During construction, they considered painting the bridge black and yellow to give it visibility. However, when the architects saw the beautiful reddish-orange hue of the primer, they decided to keep it. We have to say we're glad they didn't go with the original idea!

4

Good citizens

Image: Zoshua Colah

San Franciscans redefined what it meant to be good citizens when, during the Great Depression, they helped fund the Golden Gate Bridge by putting up their homes and farms as collateral to make the project a reality. This incredible show of faith during one of the nation's toughest economic times is truly inspiring.

5

Really heavy

Image: Leo_Visions

With its immense size and structure, it’s no surprise that this imposing bridge is incredibly heavy. Even so, the number might still shock you: The Golden Gate Bridge weighs around 894,000 tons! That's nearly the equivalent of 2.5 Empire State Buildings!

6

5,000 - 10,000 gallons

Image: JOSHUA COLEMAN

Its weight goes hand in hand with its size: the bridge is about 1.7 miles long from end to end, and its towers rise 746 feet above the water. This means the amount of paint required to cover it is anything but small. To repaint the bridge, between 5,000 and 10,000 gallons of its iconic color are used.

7

Dangerous challenges

Image: Anastasia R.

The completion of the Golden Gate Bridge had its challenges. In 1935, a powerful 7.8 magnitude earthquake struck the area, causing the entire San Francisco Bay Area, including the bridge under construction, to shake violently. One worker reportedly recalled that the south tower swayed 16 feet in each direction while several of his colleagues stood on it!

8

200,000 pedestrians

Image: fan yang

The grand opening of the Golden Gate Bridge on May 27, 1937, was far from low-key. Before it was opened to cars, a "Pedestrian Day" event took place, where an extraordinary 200,000 people walked across the city's brand-new bridge, each paying 25 cents to do so.

9

Once the tallest of its kind

Image: Casey Horner

As a suspension bridge, the Golden Gate Bridge is impressive not only for its size but also for its engineering. In fact, when it opened in 1937 and until 1964, this San Francisco landmark held the world record as the tallest suspension bridge in the world!

10

800,000 people

Image: Kiko Camaclang

Yes, the 200,000 people who attended the bridge's opening made for a huge crowd. But 50 years later, that number quadrupled! That's right; during the 50th anniversary of its opening, around 800,000 people walked across the iconic Golden Gate Bridge. It's hard to even imagine what such a giant crowd would look like!
