Today is the anniversary of the liberation of Auschwitz-Birkenau on January 27, 1945 by the 60th Army of the First Ukrainian Front. Visit http://auschwitz.org/en/
In 2014 I visited Berlin and went through the “Memorial to the Murdered Jews of Europe”, called Holocaust Memorial by most Berliners. Opened in May 2005, the memorial in Berlin-Mitte is located near the Brandenburg Gate. It took 17 years for the Memorial to be completed in Berlin. Its foundation stone was a Bundestag resolution passed on June 25, 1999 to erect a Memorial to the Murdered Jews of Europe. This was followed by years of discussion and deliberation, until the Monument was completed on May 8, 2005. US architect Peter Eisenman conceived the winning design consisting of 2711 rectangular blocks of concrete laid out in grid formation, recalling tombstones.
Here are pictures from my visit:
