A vast Holocaust memorial designed by the American architect Peter Eisenman. Opened in the spring of 2005, this gigantic abstract artwork covering an entire block near the Brandenburg Gate, including an underground information centre with extensive details on the Holocaust and the people who died during it. The blocks start out at ground level on the outer edges of the memorial, and then grow taller towards the middle, where the ground also slopes downwards. Entry to the information centre is free although priority is given to prebooked groups so there may be a short queue.
