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.

8

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.

The cowboy hat on the bed

Image: Olivier Piquer

For a proper cowboy, a hat is as important as their horse or saddle. This means that there’s a protocol around this garment that needs to be followed, one important rule being that a hat should never be placed on top of a bed.

Why? There are several explanations, including the idea of bad spirits living in your hair, the old custom of placing a deceased person’s hat on top of their coffin, or the more practical reasoning of wanting to avoid lice. No matter the origin, no respectable cowboy would place his hat on the bed unless he wanted to attract misfortune his way.

The Appalachian woods

Image: Elijah Mears

The Appalachian Mountains are filled with myths and legends, and certain rules are passed down and followed by nearly everyone, even those most skeptical about the supernatural. Many of these rules concern the woods and how one should behave in them : don’t go into the woods from dusk till dawn, don’t leave the marked trail, ignore any unknown voice calling you, and don’t look too closely into the trees.

While these rules could be explained by the simple reason of the woods being the hiding place of bandits in the past, and a difficult place to navigate in the dark, they have also been regarded as a place filled with spirits and supernatural beings, which no one wants to come across.

Seeing Mothman

Image: James Wainscoat

A local cryptid celebrity in Point Pleasant, West Virginia, the Mothman has allegedly been sighted several times since the 1960s. Many legends and beliefs have formed around his figure, one of them being that coming across the Mothman is a sign of an impending tragedy .

This belief gained strength after several reported sightings occurred just before the collapse of the Silver Bridge in 1967. Since then, the Mothman has been considered a harbinger of doom and a bad omen.

A mirror to ward off the devil

Image: Denny Müller

Louisianans have many myths and beliefs, especially those rooted in Cajun culture. Influences from French Acadia, Spain, and Western Africa have been incorporated into popular wisdom in a distinctly unique way.

One Cajun custom advises the use of a mirror to repel M’su Diable or "Mr. Devil." M’su Diable is known for being very vain, so he will never waste the opportunity to admire himself. If you hang a mirror in the porch, next to the door, he will stay there all night instead of entering the house, and the sunrise will scare him off.

Eating black-eyed peas on New Year’s Eve

Image: Nguyen Dang Hoang Nhu

Each holiday has certain foods associated with it, many of which are considered non-negotiable. For many Southern households, New Year’s Eve is synonymous with black-eyed peas, which are said to attract good luck and prosperity for the coming year.

While it’s a popular belief, this custom has distinctly historical origins. After the Civil War, black-eyed peas became a staple food across the South and saved more than one family from starvation. Today, they are often paired with collard greens, which are said to represent dollar bills.

Rocking an empty chair

Image: Robin Jonathan Deutsch

Irish and Scottish settlers brought with them a deeply rooted belief: you shouldn’t rock an empty cradle, cause you might wake the spirits. Across the South and the Appalachians, this belief transformed over time and became attached to another object: the rocking chair.

Often placed on porches or near the fire, a rocking chair moving on its own was believed to be occupied by a supernatural being . If someone rocked an empty chair, the spirits might consider this an invitation into the house.

The color of the porch

Image: Thomas Park

If you like the look of Southern front porches, you may have noticed that they often feature a pale blue ceiling. The use of haint blue—a collection of pale blue-green shades —is not an aesthetic choice, but a spirit-warding custom stemming from the enslaved Gullah Geechee people.

By painting the ceiling (and sometimes doors, windows, and shutters) blue, spirits might confuse it with the sky and pass through it, or with water, and avoid it. Over time, the tradition of haint blue— haint being an alternative spelling of _haunt_—spread throughout the South.

Bananas on a boat

Image: Ian Talmacs

Bananas are a pretty convenient fruit: they’re tasty, nutritious, and come naturally prepackaged. But don’t try saying that to Alaskan fishermen. They’ll tell you that bananas should never be brought on a boat, or no fish will be caught.

There are two possible origins of this belief. Some say the aversion to bananas stems from the old ships that carried this fruit—they sailed as fast as possible to prevent the cargo from spoiling, which disturbed the water and scared away fish. Others say that overripe bananas attract fruit flies and were believed to cause other food to spoil.

The tail of the cow

Image: Screenroad

Florida has historically been the state most prone to hurricanes, which has led to the development of superstitions and beliefs around the subject. A common belief involves cows, or more specifically, their tails.

If a cow holds its tail straight up, many Floridians say it means a hurricane is on the way . There are many scientific reasons for cows to hold their tail upright, and none have to do with weather prediction, but as far as we know, Floridians have not been proven wrong yet.

Whistling at night

Image: Lukas Robertson

Many cultures across the world refrain from whistling at night to avoid attracting spirits and malevolent beings. For Hawaiians, it is not just any spirit**. A whistle after dark might attract the** Huakaʻi pō or Nightmarchers , the ghosts of ancient Hawaiian warriors.

If you happen to come across them, your only hope is to lie on your stomach and avoid looking at them as a sign of respect. If you are lucky enough to be a descendant of a warrior, they will recognize you and protect you. But just to be on the safe side, it’s best to leave the whistling for daytime.

1

Spanish

The fact that Spanish is the second most spoken language in the U.S. comes as no surprise if we consider that at least 18 of the current 50 states were once part of the Spanish Empire. This, combined with migration from other Hispanic territories, means that around 40 million people speak Spanish at home in the U.S., nearly 13% of the population.

Native Spanish speakers in the U.S. have developed their distinct dialectal variants, such as New Mexican Spanish in the states of New Mexico and Colorado, Puerto Rican Spanish , or Spanglish .

2

French

French is, after Spanish, the most taught foreign language in schools. But did you know that more than a million Americans speak French at home ? Historical events such as the Louisiana Purchase or the French and Indian War in Canada meant that native French speakers migrated to the U.S. or became American when French-speaking territories were incorporated.

Nowadays, the French language presents three main dialectal groups in the U.S. , mainly located in Louisiana and the New England region. So, if you were planning a holiday in NOLA or Lewiston, you might want to brush up on your ouis , bonjours , and mercis .

3

Navajo

Compared with other languages on this list, the Navajo speaker population might seem small, with around 170,000 native speakers . However, it is the most widely spoken Native American language , with most of its speakers located in the Southwestern U.S.

Navajo is famous for its use as a code during World War II . Its complex grammar and the fact that, at the time, it wasn’t a written language, significantly reduced the chances of enemy forces deciphering transmissions, and even native Navajo speakers wouldn’t have been able to understand the code used.

4

Chinese

When we think about Chinese immigration into the U.S., we sometimes forget that China is a multicultural, multiethnic country, and that not all Chinese immigrants spoke the same language or came from the same region.

It is reported that more than 3 million people in the U.S. speak a Chinese language at home, with Mandarin, Cantonese, and Hokkien accounting for the majority of those speakers.

5

German

Although more than a million Americans speak German at home , nearly half of them would have issues communicating with a German person. This is because there are several variants of German spoken in the U.S., such as the Pennsylvania Dutch, the Plautdietsch, or the Alsatian , mainly spoken by Amish or Mennonite communities, or the Yiddish , widely spoken in Jewish communities.

Standard German is the second most spoken language in North Dakota , while Texas German , a U.S. variant, is still spoken in the state of Texas by the descendants of 19th-century German settlers.

6

Hawaiian

Hawaiian is recognized as one of the official languages of the state of Hawaii , but is classified as an endangered language . It is estimated that only 2000 of its 30,000 speakers learned it as a first language. In the late 19th Century, Hawaiian was banned from schools , which significantly reduced the number of speakers, but conservation efforts over the past decades have proven successful in revitalizing the language .

Hawaiian Pidgin , an English-based creole language , is also spoken by more than half a million Hawaiians and has been influenced by languages such as Portuguese, Cantonese, Japanese, Okinawan, and Korean .

7

Italian

Italians are one of the most notorious U.S. communities of immigrant descent, with their way of speaking being one of the main traits associated with Italian-Americans . But nowadays, of the more than 15 million Italian-Americans, only 700,000 are fluent in standard Italian .

Many Americans of Italian descent speak a pidgin (a simplified language that results from the contact of two groups) that mixes English, standard Italian, and regional Italian dialects , with words like mootsarell’ (from mozzarella ), gabagool’ (from capocollo ), or latte (from caffelatte ). Something to think about next time someone orders a pumpkin spice latte at Starbucks.

8

Vietnamese

You might not know this, but despite Vietnamese immigration being relatively recent compared to other Southeast Asian communities, Vietnamese is the sixth most spoken language in the U.S . This is a result of a conscious effort by the Vietnamese community to maintain the language and pass it down to new generations.

Before the start of the Vietnam War, it was estimated that only 3,000 people of Vietnamese descent lived in the U.S. Currently, around 2.3 million individuals identify as Vietnamese-American, 1.5 million of them being fluent speakers of the language .

9

American Sign Language (ASL)

When we say ‘languages other than English’, most of the time we are not thinking of sign languages . For many people, sign language is a variant of a spoken language, but sign languages have their own grammar, syntax, and rules that make them full-fledged languages.

It is estimated that American Sign Language (distinct and separate from the sign languages of some other anglophone countries) has between 250,000 to half a million native speakers , with thousands more as second-language users.

10

Arabic

The presence of the Arabic language in the U.S. dates back hundreds of years, with records of Arabic speakers from the 17th Century . Arab-Americans are estimated to be more than 3 million, of diverse backgrounds, with ties to at least 22 Arabic-speaking countries .

Following historic events in the past decades, many Arab-Americans have stopped using the language or teaching it to their children to avoid prejudice or stigma . Nonetheless, Arabic is still one of the most spoken languages at home for U.S. citizens , with more than a million users.
