The City of Eridu is a Sumerian settlement situated about 22 km to the south of Nasiriya, and 40 km south west of the traditional site of the Garden of Eden (at present Mughair).
It is one of the very first villages of Mesopotamia (and the World) that started to grow into cities as a result of effective irrigation agriculture development.
In the Sumerian literature, Eridu was on the see-shore. The early settlement of this city started about the middle of the 4th millenium BC, flourished during the early dynastic period, and went on as an important city up to late Babylonian era.
The Ziggurat of Eridu is similar to the Ziggurat of Ur, but slightly smaller. The chief god of this city was Enki; the god of Wisdom.
