One of the most impressive and controversial memorial to the Holocaust is located near Brandenburg Gate, in the Friedrichstadt neighborhood of Berlin. The Memorial to the Murdered Jews of Europe, also known as the Holocaust Memorial, was designed by New York based architect Peter Eisenmann, and consist of a sea of 2,711 charcoal-colored concrete blocks called "stelae" laid out in a grid pattern over a 4.7 acre site of undulating ground. From a distance, the memorial site looks like a graveyard with the concrete steale resembling tombstones. The concrete blocks are not uniform in size and ranges in height from a mere eight inches to over fifteen feet tall. Visitors can enter from all four sides and lose themselves in the labyrinths of narrow paths between the concrete blocks. In the southeast corner of the site, located underground and accessible via two flights of stairs, is an Information Center that holds the names of approximately 3 million Jewish Holocaust victims.
