What is the culture of origin of the hanging gardens?

The Hanging Gardens of Babylon are believed to be from ancient Mesopotamia, specifically the city of Babylon, which is in modern-day Iraq. They are often associated with the reign of King Nebuchadnezzar II, who is said to have constructed them in the 6th century BCE for his wife, Amytis of Media. While their existence is debated among historians, they symbolize the advanced engineering and horticultural practices of Babylonian culture.
