Hanging Garden's of Babylon

The Hanging Gardens of Babylon were considered one of the wonders of the ancient world. The Greek historian Herodotus described Babylon in great detail. King Nebuchadnezzar built them in 580 BC apparently for his wife Amytis, daughter of the Median King Astyages, who was homesick for the mountains and vegetation of her native land. The site was located by an archaeologist named Koldeway at the northeast corner of Nebuchadnezzar's palace near the Ishtar Gate. The gardens were probably developed on a structure like a ziggurat and built in the form of elevated terraces. Koldeway discovered huge vaults and arches at the site. He also uncovered an ancient hydraulic system like a pump drawing water from the river. The building was about 75 feet high and the gardens were at different levels which grew around and on top of a building. (Bible History Online)
