The Hanging Gardens of Babylon are considered to be one of the original Seven Wonders of the Ancient World. They were built in the ancient city-state of Babylon, near present-day Al Hillah, Babil, in Iraq. They are sometimes called the Hanging Gardens of Semiramis (in reference to the legendary Queen Semiramis).
The gardens were supposedly built by the Babylonian king Nebuchadnezzar II around 600 BC. He is reported to have constructed the gardens to please his homesick wife, Amytis of Media, who longed for the trees and fragrant plants of her homeland. The gardens were destroyed by several earthquakes after the 2nd century BC.
The lush Hanging Gardens are extensively documented by Greek historians such as Strabo and Diodorus Siculus. Through the ages, the location may have been confused with gardens that existed at Nineveh, since tablets from there clearly show gardens. Writings on these tablets describe the possible use of something similar to an Archimedes screw as a process of raising the water to the required height. Nebuchadnezzar II also used massive slabs of stone, which was unheard of in Babylon, to prevent the water from eroding the ground.
