Etemenanki Ziggurat

Built in the ancient Mesopotamian valley, ziggurats were great stepped pyramids that dominated the landscape. At the tops (closer to the sky) were great shrines, where sacrifices were offered to the gods. The Etemenanki Ziggurat in Babylon was dedicated to Marduk and survived until the third century BC, but their is debate over when it was built. It may have been the great ziggurat described in literature going back two thousand years BC, or it may have been built as recently(?) as 900 BC. It has been suggested that this great pyramid may have been the basis for the story of the Tower of Babel. Recently a LEGO version was unveiled by Michal Herbolt, aka gearcs:
