According to ancient Greek poets, the Hanging Gardens of Babylon were built near the Euphrates River in modern-day Iraq by the Babylonian king Nebuchadrezzar II around 600 B.C. The gardens were said to have been planted as high as 75 feet in the air on a huge square brick terrace that was laid out in steps like a theater. The king allegedly built the towering gardens to ease his lover Amytis’ homesickness for the natural beauty of her home in Media (the northwestern part of modern-day Iran). Later writers described how people could walk underneath the beautiful gardens, which rested on tall stone columns. Modern scientists have deduced that for the gardens to survive they would have had to be irrigated using a system consisting of a pump, waterwheel and cisterns to carry water from the Euphrates many feet into the air. Though there are multiple accounts of the gardens in both Greek and Roman literature, none of them are firsthand, and no mention of the gardens has been found in Babylonian cuneiform inscriptions. As a result, most modern scholars believe that the existence of the gardens was part of an inspired and widely believed but still fictional tale.
