To my embarrassment, I had never noticed anything like it during numerous visits to Germany. I talked with my niece about this “find” and she informed me that these stones are called “Stolpersteine” (Stumbling Stones) and that they are found across Europe.
Artist Gunter Demnig created and placed the first Stolperstein in 1992 in Cologne. Stolpersteine are embedded in the street in front of the last chosen home of a Jewish person. Here is a link to the story and background of these stones.
I know I will be walking with my eyes wide open to see and remember those who fell victim to a regime that caused indescribable horror and pain.
