Where was Babylon located in the world?
Babylon
European travelers in many cases could not discover the city's location, or mistook Fallujah for it. Twelfth-century traveler Benjamin of Tudela mentions Babylon but it is not clear if he really went there. Others referred to Baghdad as Babylon or New Babylon and described various structures encountered in the region as the Tower of Babel. Pietro della Valle found the ancient site in the seventeenth century and noted the existence of both baked and dried mudbricks cemented with bitumen.
Fall of Babylon
It has long been maintained that the foundation of Seleucia diverted the population to the new capital of Babylonia, and that the ruins of the old city became a quarry for the builders of the new seat of government, but the recent publication of the Babylonian Chronicles of the Hellenistic Period has shown that urban life was still very much the same well into the Parthian age (150 BCE to 226 CE). The Parthian king Mithridates conquered the region into the Arsacid Empire in 150 BC, and the region became something of a battleground between Greeks and Parthians.
