The Memorial to the Murdered Jews of Europe (German: Denkmal für die ermordeten Juden Europas), also known as the Holocaust Memorial (German: Holocaust-Mahnmal), is a memorial in Berlin to the Jewish victims of the Holocaust, designed by architect Peter Eisenman and engineer Buro Happold. It consists of a 19,000-square-metre (200,000 sq ft)  site covered with 2,711 concrete slabs or “stelae“, arranged in a grid pattern on a sloping field. The stelae are 2.38 metres (7 ft 10 in) long, 0.95 metres (3 ft 1 in) wide and vary in height from 0.2 to 4.7 metres (7.9 in to 15 ft 5.0 in). They are organized in rows, 54 of them going north–south, and 87 heading east–west at right angles but set slightly askew. An attached underground “Place of Information” (German: Ort der Information) holds the names of approximately 3 million Jewish Holocaust victims, obtained from the Israeli museum Yad Vashem.
