There is a very special kind of art hidden in the Potsdam district of Groß-Glienicke: Regina Görgen has created a sculpture trail here. On a circular path through the forest behind a house, accessible from the forest or from the "Bullenwinkel" road, visitors come across around 30 funny sculptures made of concrete, wood and other materials. And thought-provoking pieces, such as "Aardvark. Beware, invasive species!"
