Babylon was a city-state of ancient Mesopotamia, the remains of which are found in present-day Al Hillah, Babil Province, Iraq, about 85 km (55 mi) south of Baghdad. All that remains of the original ancient famed city of Babylon today is a mound, or tell, of broken mud-brick buildings and debris in the fertile Mesopotamian plain between the Tigris and Euphrates rivers, in Iraq. Although it has been reconstructed, historical resources inform us that Babylon was at first a small town, that had sprung up by the beginning of the third millennium BC (the dawn of the dynasties). The town flourished and attained prominence and political repute with the rise of the First Babylonian Dynasty. It was the "holy city" of Babylonia by approximately 2300 BC, and the seat of the Neo-Babylonian Empire from 612 BC. The Hanging Gardens of Babylon were one of the Seven Wonders of the Ancient World.
The form Babylon is the Greek variant of Akkadian Babilu (bāb-ilû, meaning "Gateway of the god(s)", translating Sumerian Ka.dingir.ra. In the Hebrew Bible, the name appears as בבל (Babel), interpreted by Book of Genesis 11:9 to mean "confusion" (of languages), from the verb balbal, "to confuse".
