What types of technology did they use to build the Hanging Gardens?

The Hanging Gardens of Babylon, often considered one of the Seven Wonders of the Ancient World, likely employed advanced irrigation technology for its time. This may have included a series of pumps, possibly powered by animal labor or water wheels, to lift water from the Euphrates River to the elevated gardens. Additionally, terraced structures made from mud bricks and stone would have been essential for supporting the various plants and creating the cascading effect attributed to the gardens. Although the exact methods remain a topic of debate, these technologies would have been crucial for maintaining the lush vegetation in a desert environment.
