The Hanging Gardens of Babylon.

   The Hanging Gardens of Babylon have long since  disappeared. 
   They were said to have been built by King Nebuchadnezzar in the 6th century 
   BC to please and console his favorite wife, Amytis. Great terraces of masonry were 
   built one on top of the other. On these were planted gardens of tropical flowers 
   and trees and avenues of palms. They were irrigated by water pumped from 
   the Euphrates River. Nebuchadnezzar and his queen could sit in the shade 
   and look down upon the beauties of the city. The walls of Babylon were often 
   included with the Hanging Gardens among the wonders of Babylon. Built by 
   Nebuchadnezzar, they were faced with glazed tile and pierced by openings 
   fitted with magnificent brass gates.
