Summer Tree
In the forest close to the charterhouse, there is an old charburner. I used a piece of charcoal I found there to make a frottage of the bark of a tree.
Along the path that leads from the parking lot to the charterhouse area, there is an audioinstallation by Christina Hemmauer and Roman Keller, titled "Summer Tree Dream" (2008), from the collection of the Art Museum Thurgau: a fir tree that starts to sing "I'm dreaming of a white Christmas" whenever someone passes by.
