<P> The Hanging Gardens are the only one of the Seven Wonders for which the location has not been definitively established . There are no extant Babylonian texts which mention the gardens , and no definitive archaeological evidence has been found in Babylon . Three theories have been suggested to account for this . One : that they were purely mythical , and the descriptions found in ancient Greek and Roman writers including Strabo , Diodorus Siculus and Quintus Curtius Rufus represent a romantic ideal of an eastern garden . Two : that they existed in Babylon , but were completely destroyed sometime around the first century AD . Three : that the legend refers to a well - documented garden that the Assyrian King Sennacherib ( 704 -- 681 BC ) built in his capital city of Nineveh on the River Tigris , near the modern city of Mosul . </P>
