​The interdisciplinary art installation ‘Blue17Circles’ shows a domain of impressive size that spans the entire globe. The result is sustainable global climate art that shows what our world needs now more than ever: active, cross-border cooperation for the environment and climate.

On 22 April 2026, Earth Day, schoolchildren from 17 countries on all continents will install a circle of blue-painted shoes in central locations in major cities. Together, the circles around the globe form a domain that is only now coming to life through the interaction of the participating schools. Because the address is no ordinary link.

So if you want to access the website, you have to rethink. Because protecting the environment and climate also requires a rethink – a new way of looking at our world.
The domain of blue shoes thus becomes a global symbol of change for greater sustainability, touching on all climate-related areas: from fair education and clean energy to the protection of our habitats. Through ‘Blue17Circles’, it becomes more than a message – it becomes an experience that brings people together in motion: globally, visibly and sustainably.
