We are staying a part of Rome that has very narrow cobblestone streets. Out walking recently we ‘stumbled’ upon some brass cobblestones inscribed with peoples names the dates (during WW11) they were arrested, and the dates they were either executed (usually within a couple of days) or sent to Auschwitz. It turns out these were original an art instillation project started by a German artist initially in Cologne. The cobblestones are placed outside the building the people lived in.
I found them moving memorial to these people making my knowledge of the holocaust a bit more personal.
