Human Territoriality is a selection of Roger Eberhard’s photographs of former border regions around the globe and down through the course of human history. moreSome of these borders have shifted over time, by only a few hundred meters or much more, due to climate change or manmade changes in the landscape, others have vanished with the fall of mighty empires on either side. Eberhard’s photographs, supplemented by in-depth captions, help us to grasp the protean puzzle of the world’s cartography. In a time of mass migration, border walls and spreading nationalism, they reveal the inherent instability of these man-made demarcations.
