The artist took nearly four hundred young birch trees from the area surrounding Auschwitz-Birkenau concentration camp where during World War II the ashes of those murdered there had been scattered. Over three hundred trees were taken to Berlin where, during the Berlin Biennale of Contemporary Art, they were planted in different locations, including parks, school gardens, cultural institutions and in memorial places connected with deportations and the Holocaust. The rest of the trees Surowiec planted in his garden or presented to friends. Three trees were included in the Poland – Israel – Germany: The Experience of Auschwitz exhibition and after it was closed, they were planted in front of the museum and thus became part of the MOCAK Collection. The trees are not only live monuments whose task is to remind people about the Holocaust but also the inheritors of its victims.
