Blog > Sister Cities of Düsseldorf — a call for postcards

Have you ever heard of sister cities, also known as twin towns? It’s a concept in which “two cities or towns in geographically and politically distinct areas are paired, with the goal of fostering human contact and cultural links”. Collaborations between the cities can take many shapes (for instance, exchange programs or commercial ties), but the goal is simply to unite the towns on a meaningful level.

Right after the Second World War for example, a lot of cities in the UK and Germany came together in this way, helping promote peace and reconciliation. Sounds like a good idea, right? We firmly believe that projects focused on cross-cultural bonds and dialogue make the world a better place, by helping people open their minds to different realities and points of view. This is what Postcrossing is all about as well, so in a way, connecting cities is a lot like connecting people… just on a different scale! 😊

This year, Düsseldorf is celebrating the 30th anniversary of its connections with three sister cities: Haifa (IL), Chemnitz (DE) and Reading (GB). Despite their differences, these three cities have been finding ways of collaborating and expanding their horizons together for the past 30 years. For instance, they’ve organised internships and student exchanges, sports events, donations to each other in times of need and even brought artists together to build this huge mural in Düsseldorf!

To celebrate this milestone, the city of Düsseldorf is partnering with Postcrossing to create an international postcard exhibition that will allow the world to join in on the celebrations. Nothing says “connections across borders” like postcards, so we believe this is the perfect medium to expand their jubilee to the entire world.

And this is where YOU come in! Düsseldorf kindly invites all postcrossers to take part on the postcard exhibition by sending in postcards with well-wishes and thoughts on sister cities. To participate, choose a postcard from your area and send it to:

Sister Cities of Düsseldorf
(The address has been removed as exhibition is already taking place, so postcards are no longer needed.)

We encourage everyone to congratulate Düsseldorf, Haifa, Chemnitz and Reading on their triple jubilee and also to write about sister cities on your postcards! Is your city or town twinned with another one? What do you think of the concept? And do you have any good ideas for cooperations between sister cities?

And as a bonus, the nice people from Düsseldorf’s town hall have reserved 100 specially designed postcards to send out to 100 randomly chosen participants of the exhibition! For a chance to win one, just include your email address on the postcard you send. Don’t worry — your email addresses will be covered for the duration of the exhibition.

All postcards will be displayed on Café Europa (Marktplatz 6 a) from June 30th onwards, so you have until then to send in yours. And if you’re around, mark your calendar and send us photos! We’d love to see your beautiful postcards in all their shiny glory! 😍

PS – If you were the mayor of your town and could twin it with another one, which one would that be? And what would you suggest for your first cooperation? Let us know in the comments!

Love this idea! :) I'll join for sure! :D

chrisbonham11, United Kingdom

As an inhabitant of Reading, I'll definitely be getting involved! Unfortunately Reading is not a city in UK terms: it is one of the UK's largest towns but has not had city status conferred on it by the monarch (yet...).

Oh yes - not very often that Düsseldorf is on the map of postcard lovers! As a "local" I will be sending a card and definitely visit the exhibit! Thanks for letting us know.

SylviaM, United States of America

I just mailed them a postcard today from my city of Las Vegas, Nevada -- which I discovered has no sister cities : (

Zabrze in Poland

inPhobos, Germany

What a wonderful event! Will try to visit it!
Whenever I send a postcrossing card into one of our twin cities, I will mention that "we" are twins, but sadly, most recipients had never heard of it.
Hopefully, this blog posting will get everyone motivated to look up "their twins".

Xiaoi, Germany

Nice idea. Düsseldorf is our neighbouring city and probably I'll send a card from Neuss to our neighbours or a Haifa-card from my last IL-trip. Actually I thought about sending a card directly from Haifa, but I'll be there only from 1st July on. Damn. :(

meiadeleite, Portugal

@SylviaM If I was the mayor of Las Vegas, I would suggest a twinning with Macao! 🙃

Heepy, United States of America

I live in Des Plaines, a suburb of Chicago. Chicago has 26 sister cities, from Accra (Ghana) to Warsaw (Poland).

My suburb's sister city is Nailuva, Fiji!!!! Oh, to receive a postcard from there would be awesome!

Thank you for this topic as I learned something new about my area! I also learned that Chicago is sister city to Toronto (Canada) where one of my good friends lives. (Yes, I told her about Postcrossing and she recently became a member).

Iside82, Italy

Last year I had fun collecting at least one card from everyone of Genoa sister cities (Marseille in France, Columbus and Baltimore in US, Odessa in Ukraine, Chios in Greece, Rijeka in Croatia and the district of Beyoğlu in Istambul in Turkey). Some of them were old colonies of the maritime republic of Genoa during the Middle Ages or follow maritime ports :)

Jacque53, United States of America

I just mailed my postcard! Scottsdale, Arizona is sister cities with 8 other cities which are:

(3) Cairns, Queensland, Australia
(4) Kingston, Ontario, Canada
(5) Haikou, Hainan, China
(6) Marrakech, Morocco
(7) Uasin Gishu, Kenya
(8) Killarney, Ireland

This has inspired me to get involved with my city’s Sister City program! This is right up my alley, so to speak!

Thanks Anna!

Peskipixi, United States of America

I live in New Braunfels, TX and we are Sister Cities with Braunfels, DE. The Sister Cities agreement was signed in 2010, but there has been a partnership between our cities since 1925. More than 90 years!

Well, I am from São Paulo - Brazil, and there are... 42 Sister Cities. frankly? sounds too many for me... Probably due to the big heart of people.

I was surprised to find that we had 10!

booboo_babies, United States of America

I live in Lubbock, Texas. According to Wikipedia, Lubbock is presently a sister city to Musashino, Tokyo, Japan, used to be a sister city to Leon, Mexico and proposed sister cities include Can Tho, Vietnam, Ulsan, South Korea or Ciudad Acuna, Mexico.
If I were Mayor of Lubbock, and could pick a sister city in the United States, I would pick a city that is the total opposite of us. Like Boston. From what I understand, Boston is liberal, whereas Lubbock is totally conservative. Lubbock was voted the second most conservative area in the United States in a survey (Salt Lake City came in first.)

Kiathemoon, United Kingdom

Reading is my hometown so I will definitely send a postcard in celebration!

XeniKo-ts, Serbia

Interesting/ In the times of the USSR we had a city or a town brother. My native town Petrozavodsk had a brother in France - La Rochelle (if I am not mistaken in the spelling) It was very popular, I think there is still a cultural connection between them. It is a very good thing for people, it makes our world more friendly, more reasonable and safe.

gagema, Germany

My hometown Steinhagen is twinned with Wourden in The Netherlands and Fivizzano in Italy. Every year there is a guided day trip to Wourden for our citizens. Unfortunately Fivizzano is too far away for a day trip!

meiadeleite, Portugal

@ChimeBelle You totally should! Tell them what you think of their collaborations with other cities, or let them know a city you'd like Düsseldorf to be twinned with! :)

I have heard of twin cities in other states, in the US, but I have never heard of cities that are in different countries. :-)

Heepy, United States of America

I sent my postcard yesterday. I am also going to contact my Chamber of Commerce to find out more about my suburb's sister city as there is no information available. Hopefully I can get somewhere with this!

Ejderha, Netherlands

Thank you for sharing this, it's a wonderful idea!
My postcard will start its journey tomorrow. (^_^)
The sister cities of 's-Hertogenbosch are: Trier (the oldest city in Germany) since 1968; and Leuven (BE) since 1185 when Duke Henry I of Brabant granted 's-Hertogenbosch city rights.

PostcardPal, Canada

I would like to participate in this event! I'll start my search for an appropriate postcard showing my locale. (Fredericton, New Brunswick, Canada). How can we find out if our town already has a sister-city? I'd welcome any one who wants a 'twin'. :)

Knerq, United States of America

If I were the mayor, I would choose to twin my city to a place in Canada.

siobhan, Germany

My hometown, Leverkusen, has 9 sister cities:
- Oulu in Finland (we have an Oulu Lake and an Oulu Street)
- Bracknell Forest in England
- Ljubljana in Slovenia
- Nazrat-Illit in Israel
- Chinandega in Nicaragua
- Schwedt in Germany (these German-German partnerships are remains from when there were two German states)
- Villeneuve d’Ascq in France
- Racibórz in Poland
- Wuxi in China

I have exchanged postcrossing cards with Oulu (both ways several times), Ljubljana (both ways) and Wuxi (both ways). It would be totally cool to send to or receive from all of them one day, but as some are rather small (not unlike my own town ;-)), it would be quite a big coincidence.

clouisesz, United States of America

I will be mailing a postcard, I looked and can not find a sister city to St. Charles, IL I need to contact someone to find out for sure.

senation1s, United States of America

Sending a postcard your way! I think this is wonderful that you all show unity with one another. My town does not have a sister city but it should! Congratulations to you all. I hope my postcard makes it to you all quickly!
