Description:

The King Hammurabi is the most famous king of the Babylonian kingdom. The whole kingdom flourished under his rule. His son Nebuchadnezzar is the one who built the Hanging gardens of Babylon, one of the Seven wonders of world.
Nebuchadnezzar ruled the country for 43 years from 605 BC. He constructed impressive array of temples, palaces and streets. It is being told that he built this garden to please his wife, Amyitis. Amyitis, daughter of the king Medes seems to have had a passion for mountainous surroundings. There are some other accounts which say that this wonder of the world was actually built by the Assyrian Queen Semiramis.
The ancient accounts of this hanging gardens (one of the seven wonders of the world) describes the structure to be a stairs like one. The Greek geographer Strabo, describes it as , "the garden consists of vaulted terraces raised one above another, and resting upon cube-shaped pillars. These are hollow and filled with earth to allow trees of the largest size to be planted. The pillars, the vaults, and terraces are constructed of baked brick and asphalt."
The irrigation system was supposedly the complex part built on this gardens. This region had very scarce rains. Slaves were used to push the water upwards using some ancient method of irrigation. Of course there must be some exploitation of slave labor to maintain one among the seven wonders of the world. The gardens did not really hang on the roof using cables or ropes. But this name from the sense that it was built on the roof top. Some accounts state that the gardens are 400 by 400 feet and 80 feet high.
