This Austrian soccer stadium is assuming a pretty unique aesthetic that has nothing much to do with sports. The Wörthersee Stadium in Klagenfurt has been covered with over 300 adult birch, willow, maple, and oak trees for artist Klaus Littmann’s “For Forest” installation.

The largest public installation ever to take place in Austria, “For Forest” is meant to change with the time of day and give visitors and ever-evolving experience, especially with the change of colors that comes with fall. “From 10 AM until 10 PM daily,” the official description reads, “audiences will experience a unique panorama of trees, day and night, under natural light or by floodlight.”

The goal of the unique installation is to encourage people to think about forests, and how we can better preserve and care for them. The installation’s official press release says that it “aims to challenge our perception of nature and questions its future. It seeks to become a memorial, reminding us that nature, which we so often take for granted, may someday only be found in specially designated spaces.”

The installation has been open to the public since September 8 and will remain open until October 27, when it will be replanted in a public space outside the building. Admission is free.
