Officially known as the Denkmal für die Ermordeten Juden Europas (Memorial for the Murdered Jews of Europe), this undulating field of irregularly angled concrete stele occupies the former East-West no man’s land. Its minimalist interpretation forces you to wander through the maze-like environment with nothing to focus on but your own internal emotions and experiences. The results can be more profound than the usual immersion in Nazi horrors provided at most historical sights.
