This is a tribute to the Jews who were killed and fell into the Danube. It is really moving to see the shoes they have displayed along the sidewalk. The Germans just lined them up along the edge of the river and shot them. Some of the shoes have candles in them. I'm not sure when but sometimes they light the candles at night. Sister Baughman says it's also very cool to see it at night when the candles are lit. Very sad that so many horrible things have happened here.
