Ancient Babylon great during Nebuchadnezzar

Ancient Babylon reached its greatest glory during King Nebuchadnezzar (604-562 BC). The city was divided into two equal parts by the River Euphrates. It had 25 avenues, 150 feet wide, which ran across the city from north to south. The same number crossed them at right angles from east to west, making a total of 676 great squares, each nearly 3/4 of a mile on each side. The entire city of Babylon, presently called Hillah, was an immense square totaling 15 miles having a population of over 30,000. (Source Unknown).
