A lighted glass stripe cuts across the floor of the Hall of Witness, but it is at a slight angle, as is everything in the room. Nothing is lined up straight with the walls; everything is out of kilter so you get the subtle suggestion that something is not quite right here. The stairs to the second floor, at one end of the Hall of Witness, look like a ladder in a picture which appears to be smaller at the top.
At the top of the stairs is a gentle arch which is an exact duplicate of the arch over the doorway of the brick gatehouse, through which the trains rolled into the death camp at Birkenau in Poland.
