Höss’ former home sits cheek by jowl with Auschwitz, literally just metres away. It has been bought by a US organisation called the Counter Extremism Project and transformed into the Auschwitz Research Centre on Hate, Extremism and Radicalization (ARCHER) at House 88. A former symbol of hate is now a place where people can learn how to fight extremism and anti-Semitism. “We reclaimed this house after 80 years to do something positive,” says Purski, a political scientist and educator who researches extremist ideologies for the Counter Extremism Project.
