Book excerpt: Internationally renowned and award-winning historian Dr. Robert Jan van Pelt's The Evidence Room is a chilling exploration of the role architecture played in constructing Auschwitz - arguably the Nazis' most horrifying facility. The Evidence Room is both a companion piece to, and an elaboration of, an exhibit at the 2016 Venice Architecture Biennale, based on van Pelt's authoritative testimony against Holocaust denial in a 2000 libel suit argued before the Royal Courts of Justice in London.
