The ancient city known for its Hanging Gardens, one of the Seven Wonders of the Ancient World, is Babylon. Located near present-day Hillah, Babil, in Iraq, Babylon flourished under the rule of King Nebuchadnezzar II in the 6th century BC. The Hanging Gardens are often described as an extraordinary series of tiered gardens, said to have been built to please Nebuchadnezzar's wife, Amytis, who missed the green hills of her homeland. Though the actual existence of these gardens is debated among historians, they symbolize the grandeur and innovation of Babylonian architecture and engineering.
