The recent theft and retrieval of the infamous "Arbeit Macht Frei" ("Work Sets You Free") sign that marks the gateway into Auschwitz has reignited debate over what should be done with the sombre monument to one of humanity's darkest hours.
Last week Poland's culture minister promised the equivalent of $137,000 for improving security at the site where more than one million people died during the Holocaust.
But Robert Jan Van Pelt, an architectural historian and a leading expert on Auschwitz, says it may be time to consider other strategies for the site, which is split into two camps, Auschwitz and Birkenau. They sprawl over nearly 500 acres.
By allowing nature to take over the site, do we run the risk of allowing humanity to forget what happened and set the stage for future questioning of the Holocaust?
Ninety-nine per cent of what we know we do not actually have the physical evidence to prove . . . it has become part of our inherited knowledge.
