Not everyone will have a chance to visit Holocaust and World War II sites to learn firsthand how human beings became mass murderers. For those who can’t, this online guide provides a pictorial window into this tragic legacy. Some of the images, like the entrance to Auschwitz-Birkenau, are immediately familiar. They are global icons, known to all. Others, like the hot dog stand at Auschwitz are not. They actually may shock those unfamiliar with the camps’ current conditions. This is how the legacy appears in the more than 60 years since the end of World War II. While some destinations attract hundreds of thousands of visitors, other destinations, like the Gross-Rosen Concentration Camp, are ignored. Nearly all the major camps have museums and displays of how persons were interned, tortured, and murdered. These photographs were taken in seven European countries between 2000 and 2001.
