The Hanging Gardens of Babylon have long been shrouded in myth, their location unknown. Now, thanks to the groundbreaking work of scientist Stephanie Dalley, we can finally pinpoint where these legendary gardens were located, how they appeared, and how they were constructed. Unlike the other Seven Wonders of the Ancient World, no archaeological evidence has ever confirmed their existence. This documentary follows Stephanie Dalley as she journeys to a perilous region of northern Iraq to gather proof for her theory: that the gardens were built by the Assyrian king Sanherib, not Nebuchadnezzar II, and a full 700 years earlier than previously believed.
