I was in Berlin over the weekend - got home last night - and visited Sachsenhausen. This morning my partner asked "what was something historic that you saw?" It took just a beat for me to say "the ovens." The first one, you can only see through a slit in a wall. The later ones, at Station Z, are almost intact. Sachsenhausen lets you cut flowers from a small garden for a small donation, to leave in remembrance. Not me though. I just left a visitation stone.
