One of the 7,000 pairs of Oaks and basalt stones, after 26 years
7000 Oaks – City Forestation Instead of City Administration (German: 7000 Eichen – Stadtverwaldung statt Stadtverwaltung) is a work of land art by the German artist Joseph Beuys. It was first publicly presented in 1982 at the documenta 7. With the help of volunteers, Beuys planted 7,000 oak trees over several years in Kassel, Germany, each with an accompanying basalt stone.
In regard to the extensive urbanization of the setting the work was an extensive artistic and ecological intervention with the goal of enduringly altering the living space of the city. The project, though at first controversial, has become an important part of Kassel's cityscape.
After five years, the project ended in 1987 on the occasion of documenta 8. It is still alive.
