Germany - Berlin "Holocaust Memorial".

Was in Germany 2010 for a few weeks. A very interesting country with much to see and do. This Berlin film of the "Holocaust Memorial" just a 5 minute walk from the 'Brandenburg Gate'. Caused controversy for some having it in Berlin I was told. many theories as to why this design - many ideas. Designer has not let on! One theory from memory is that if you multiply the number of stones by itself for each stone equals the number killed... Another is that the early stones are shorter and as you walk this reflects increasing oppression of the era.
