I have dealt separately with the Jewish museum which is a must see. The above is a
memorial to those Jews who lost their lives in the Holocaust. It is not supposed to represent anything in particular but has been likened to a cemetery. It was controversial on two scores. The company producing the anti-graffiti substance was linked to the suppliers of Zyklon B to the Nazis and other minorities who had suffered, such as Roma and homosexuals, were not included. The first problem was simply ignored, as being too costly to do anything about, and the second was solved by these other groups subsequently having their own memorials.
Note the balloon in the background. This is a massive thing with a viewing platform and it is winched up and down many times a day.
