The Hanging Gardens of Babylon is one of the seven most important wonders of the world. These gardens are located in the city of Babylon, which is believed to be a mythological legend. It is also said to have been built in the ancient city of Babylon. There is no certain information about the hanging gardens of Babylon.
The Hanging Gardens are located in the city of Hilla in the Iraqi province of Babil. The hanging gardens in the city of Babylon were not the only attractive landmark in this city, besides these gardens there were walls and masonry, which were very high value.

It is said that Nebuchadnezzar was the most famous Babylonian king, who ruled from 562 BC to 605 BC. It is said that the motive behind Nebuchadnezzar's building of these attractive gardens was to win the satisfaction of his wife, who was daughter of one of the armies commanders.
This wife was called Amidia, and Amidia had been longed for her old place of residence, the hills of the Persia. After she married, she lived with her husband in the Babylonian flats, prompting Nebuchadnezzar to build her on the hills. The height of these gardens is estimated at about 100 meters. An impenetrable fortified wall around these gardens was built about seven meters thick. Plants and flowers ponds are made and lined with lead and had been placed on the sides of the terrace.
The hanging gardens were believed to have been a long building with several balconies, making it look somewhat like a mountain, and the gardens were built on stones, which were rare at the time. The plants and flowers planted on the sides of terraces were depending on water to keep them alive. So it is believed that there was a system such as the engine pumping water either from a well located below, or from the river directly.
However, the information about the Hanging Gardens of Babylon or its location is uncertain, and there is no strong evidence that it was located near the Euphrates River to pump water from it.

Opinions about Babylon Hanging Gardens
The theories assume that the gardens were not actually hanging, but were built on either side of the balconies on a brick structure. Some descriptions claim that the hanging gardens were growing to 22.86 in the air and that people could walk under them.
There is a difference of opinion about who actually built the garden; it was said that Nebuchadnezzar was the one who built it, but it is strange that Nebuchadnezzar recorded many achievements in cuneiform, a kind of old writing that was used in the collection of records at the time, and Hanging gardens are not mentioned, prompting many scholars to believe that the gardens were built by the Assyrian Queen or even by Sennacherib, governor of Nineveh.
