ABOUT THE FIGURE: Volker Tiemann: Great piece about the right hand (2008, bronze) Between Fridtjof Nansen School and Fördegymnasium, Elbestrasse 10-20, 24943 Flensburg Description In earlier times - in some countries to this day - men were often placed on high pedestals in a state-supporting gesture so that the common people could look up to them in awe. The sculptor Volker Tiemann takes up this motif in his “Large Piece about the Right Hand” and turns it into the absurd.

Nice place by the pond. Unfortunately many trees were destroyed by a storm. But the walk around the pond is still worth it.
