We’re in Berlin for International Holocaust Remembrance Day today, looking at the monument called ‘Memorial to the Murdered Jews of Europe.’ The memorial looks rigid and ordered, with 2,711 concrete slabs arranged in a grid pattern across 4.7 acres. But architect Peter Eisenman, who designed the work, purposely skewed some of the grid, so that spaces between the slabs may shrink or grow as you walk among the gray blocks. And the gaps are intentionally so narrow that they allow only individual passage. As the visitor navigates through the grid, the subtle shifts in these spaces are meant to shatter the illusion of order and security.
