Bernhard Hoetger’s sculptures for the Plane Tree Grove on the Mathildenhöhe were the artistic highlight of the last exhibition of the Darmstadt artists’ colony in 1914: over 40 sculptural works across the entire garden area of the Mathildenhöhe, constituting an emphatic artistic synthesis of the circle of life. This volume discusses the 40 sculptures within the context of the Art Nouveau movement in Germany.>
