A vast Holocaust memorial designed by American architect Peter Eisenman stands a short walk from the Brandenburg Gate. Opened in spring 2005, it occupies an entire city block and presents an abstract field of grey concrete blocks that invites quiet reflection.
The memorial is made up of hundreds of rectangular blocks arranged in a grid. Along the outer edges, the blocks begin at ground level. Moving inward, they grow taller as the ground slopes downward, creating narrow corridors with shifting light and shadow. The changing heights and the undulating ground alter the sense of space from open and level to enclosed and disorienting.
Beneath the memorial, an information centre provides extensive details on the Holocaust and many of the people who were murdered. Entry is free. Priority is given to prebooked groups, so visitors may encounter a short queue at busy times.
