Query: Insightful use of architectural records

This book skillfully combines a history of German influence in the East with a detailed look at the death and labor camps of Auschwitz. Using the architectural records left behind as well as statements of people who were there to outline the story, the authors trace the development and changes of the Auschwitz camps from 1939 to the present day. The skillful use of architectural plans provides insight into the changing purposes the camp adapted to in its short but terrible life. Also, the authors trace the German influence in the area back to the founding of the town in 1270 and relate the camp's shifting purpose to the territorial goals of the Germans in the East both before and during the war.
