The 75th anniversary of the liberation of Auschwitz was commemorated in 2020. While the final survivors are now rapidly disappearing, mass tourism phenomena can be perceived in Auschwitz at the same time. In light of these changes, it is important to discuss the concept of remembrance and also to ask: What do the crowds of visitors see? In 2017 and 2018, Frederic Mougenot photographed the two extermination camps and locations in the so-called "Interessengebiet" (area of interest), which was largely forgotten after 1945. What is thus shown in the photographs is an invisible boundary that separates the culture of remembrance from gradual disappearance.
