On my walk home from university the other day, I came upon these Stolpersteine – “stumbling stones” – which are brass cubes laid among the cobblestones in remembrance of the Holocaust victims who once lived in various places throughout Europe.

To date more than 75,000 of these mini memorials have been laid throughout the continent.

When I tried to search the names on the stones that I had seen, I found several news articles reporting that these stones had been stolen and then replaced.
