For many dictators, such as Hitler, Mussolini and Stalin, architecture became the physical embodiment of their manic dreams, usually built on collective violence and ludicrous tyranny. Their monumental structures reveal the sham world of the dictators without exposing their horror. Hitler's plans for Berlin, deliberately compared to the works of the Pharohs, depended upon slave labour for their construction, and vast ordered ranks of humans to fill them. The scale of Stalin's grandiose, triumphalist constructions was completely dissociated from any collective meaning.
