It has been estimated that Babylon was the largest city in the world from c. 1770 to 1670 BC, and again between c. 612 and 320 BC. It was perhaps the first city to reach a population above 200,000.Estimates for the maximum extent of its area range from 890 to 900 hectares.The remains of the city are in present-day Hillah, Babil Governorate, Iraq, about 85 kilometres south of Baghdad, comprising a large tell of broken mud-brick buildings and debris.
