An Austrian soccer club has temporarily moved out of its 32,000-capacity stadium so that a forest of 300 trees can be planted on the field.
Swiss artist Klaus Littmann has installed the exhibit entitled "For Forest: The Unending Attraction of Nature" on the pitch at Klagenfurt's Woerthersee Stadion to make an environmental point.
"For many, because of the current situation, this represents a memorial as part of the climate change discussion," he told Reuters at the exhibition in the lakeside city in southern Austria, near the border of Italy and Slovenia.
The Basel-based artist cited the influence of a drawing by the artist Max Peintner, "who in 1970 had the vision that one day, it could happen that we look at nature in designated areas only, for example in a crater architecture such as a stadium."
The exhibition, which opens to the public next week, has temporarily displaced Austria Klagenfurt, the second-tier team who usually call the Woerthersee home.
They will play at a smaller ground nearby until the For Forest piece is removed in late October.
