One of the four cities built in the plain of Shinar by Nimrod, founder of the Assyrian empire, Genesis 10:10 . Its site is identified by some travellers with ruins, which lie from six to nine miles west of Bagdad. There is here a ruinous structure called Tell-i-nimrood, Hill of Nimrod, consisting of a mass of brickwork 400 feet in circumference at the base, and 125 feet high, standing on a mound of rubbish. Most recently, Col. Raw claims that the site of Accad was at a place now called Niffer, amid the marshes of Southern Babylonia.
