He ziggurat is the most distinctive architectural invention of the Ancient Near East. Like an ancient Egyptian pyramid, an ancient Near Eastern ziggurat has four sides and rises up to the realm of the gods. However, unlike Egyptian pyramids, the exterior of Ziggurats were not smooth but tiered to accommodate the work which took place at the structure as well as the administrative oversight and religious rituals essential to Ancient Near Eastern cities. Ziggurats are found scattered around what is today Iraq and Iran, and stand as an imposing testament to the power and skill of the ancient culture that produced them.One of the largest and best-preserved ziggurats of Mesopotamia is the great Ziggurat at Ur. Small excavations occurred at the site around the turn of the twentieth century, and in the 1920s Sir Leonard Woolley, in a joint project with the University of Pennsylvania Museum in Philadelphia and the British Museum in London, revealed the monument in its entirety.
