The artwork covering 11'000 square meters (118'000 sq ft) was produced with biodegradable paints made from natural pigments such as charcoal and chalk and constitutes the second step of a project started at the U.N. European headquarters in Geneva in 2020. The project is supported and gifted by Switzerland to the U.N. to celebrate the 75th anniversary of the organization and the launch of the Common Agenda.
