Sachsenhausen Memorial and Museum. Sachsenhausen, Himmler’s model concentration camp. Built to give architectural expression to the Nazi world view. Designed to symbolize the subjugation of its 200,000 prisoners to the absolute power of the SS. They slept a hundred to a barracks built for a third that, shoving to get to the small toilet and washing space and crust of bread before the guards pushed them out to the windswept yard to stand in the open for hours.
