Hanging Gardens of Babylon History of the Seven Wonders of the World

The Hanging Gardens of  Babylon are one of the Seven Wonders of the Ancient World, which are engineering structures in Babylon with a cascade of terraced gardens where many species of trees, shrubs and vines grow, giving the impression of a huge green mountain. The only one of the Seven Wonders, whose final location has not been established and, moreover, the fact of its existence is questionable, since there are no surviving Babylonian texts, which mention these gardens, descriptions of the gardens are only available in late ancient Greek and Roman writers, and archaeological excavations in the area where the garden was supposed to be located have also yielded no results.
