The ancient civilization known for the Hanging Gardens is Babylon, which was located in modern-day Iraq. These gardens are often considered one of the Seven Wonders of the Ancient World, though their actual existence is debated among historians. They were described as an extraordinary series of tiered gardens that showcased a variety of trees, shrubs, and vines. According to ancient texts, King Nebuchadnezzar II constructed the gardens for his wife, Amytis, to remind her of her homeland's green hills and valleys. The gardens' elaborate design and engineering, utilizing irrigation techniques, would have made them an impressive feat of architecture.
