What is Interreg Cooperation Day?

Interreg Cooperation Day is the annual campaign through which Interreg programmes and partners bring cooperation closer to citizens. 

Every year on 21 September, and throughout the surrounding weeks, programmes across Europe organise local events of all kinds: from sports and nature activities to cultural festivals and creative workshops.

 

Facilitated by Interact, it is a chance to show people, concretely, what EU cooperation means for their lives.

A large crowd gathers on a beach at dusk around a tall, blazing bonfire. The sea is on the left, and trees border the beach on the right. Sparks rise from the fire, and groups of people are scattered along the sand.

Stronger together

Interreg Cooperation Day marks 15 years

For 15 years, programmes, projects and partners across Europe have come together to make cooperation visible to citizens. This anniversary is the moment to celebrate what we have built, and how, together, we have made our regions stronger.
