The Bicycling Tree: A Symbol of Action
With Circle4Change, we are drawing a circular line through nine countries of Europe. Starting in April 2025, a tree will cycle along this line for five months. With this we are introducing the birthday tree: ‘It’s my birthday, so I’m planting a tree’. In this way, birthday forests will be created all along the circle line, and together we will create a very large work of landscape art. It may seem impossible, but together we can do it. Join us and donate. Help the tree come full circle. Together we will activate the planting of many birthday trees!

Be part of a movement to change the world – Circle4Change
Imagine a magical circle traversing Europe, a powerful symbol of connection, nature and positive change. Welcome to Circle4Change – a unique landscape art project traversing Europe with the ambition to bring our world more in balance with nature. This is your chance to participate in something big, something that changes the future of our planet and our connection with nature.
A Circle of Connection
Circle4Change is much more than an art project – it is an invitation to work together for a sustainable and fair future. The circle connects people, regions and cultures in nine European countries, showing how by working together with nature we can create a better world. The project provides a platform for initiatives that show how we can live in harmony with the earth. From greening cities and towns along the circle to strengthening our deep connection with nature, Circle4Change creates fertile ground for new ideas, hope and action.
The Power of Bosk – Now into Europe!
Built on the success of Bosk, the walking forest that passed through Leeuwarden in 2022, Circle4Change is now making the move to Europe. Bosk brought people together, made cities greener and won prestigious awards such as the National Event Award and the Dutch Design Award. It inspired others worldwide to start similar initiatives. Circle4Change is the next step in this green revolution.
The Bicycling Tree: A Symbol of Action
In April 2025, the first major activity of Circle4Change will begin: a tree will cycle across Europe for five months. This adventure introduces a special ritual: “Plant a tree on your birthday.” Birthday trees are distributed in communities along the circle line. Thus, new forests are created, with trees that recall the power of both nature and community. The cycling tree is not only a symbol of change, but also a call to action. By planting trees, we bring nature closer to ourselves, our cities and our neighbors.
Nature Education with the Heart
Circle4Change has an important mission: to connect the new generation with nature. We want to let children and young people experience in a playful way what trees, biodiversity and a healthy earth mean to us. Nature education is integrated into everyday life and education, so that together we learn how fun and natural it is to take care of nature.
