Two British historians are leading an eight-day luxury tour of Nazi and Third Reich sites in Germany.For $3,200, participants will visit key Hitler-related sites including the lakeside villa where the plans for the Holocaust were laid out, Hitler’s vacation home in Berchtesgaden, Sachsenhausen concentration camp and the bunker where Hitler committed suicide. The tour, “The Face of Evil: The Rise and Fall of the Third Reich” is intended only for serious students of the Nazi leaders, say the tour’s leaders, Nigel Jones and Roger Moorhouse. Both have published books on Nazi Germany, and the two say they will question each participant before the tour to evaluate motivations for joining the group.
