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:

(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!
