What is the conventional archaeological date of Babylon and the Hanging Gardens (Iraq), and what alternative dates have been proposed?

Conventional date: UNESCO traces Babylon back to the third millennium BCE. From 626 to 539 BCE it was the capital of the Neo-Babylonian Empire. Alternative proposals: Open question: Did they exist, and where? Greek and Roman writers placed the gardens at Babylon, on a raised building in or next to a palace (Reade 2000). No trace has been confidently found there. So whether they existed, and where, is still open. Interpretation: Stephanie Dalley (1994): Mixed-up sources? Dalley says the Greek and Roman accounts have never matched the cuneiform texts or the digs. She argues that some mix-ups may come from older Akkadian texts, not just from error. This is her reading. Interpretation: Dalley and Oleson (2003): A water screw at Nineveh? The water screw is usually credited to Archimedes in the 3rd century BC. Dalley and Oleson argue that a 7th-century BC Assyrian text may show King Sennacherib casting one in bronze at Nineveh. It was for his palace garden. They compare this with later Greek texts about the Hanging Gardens. This is their reading of the text. UNESCO's summary: Rooted in real buildings: UNESCO's page says the Hanging Gardens story has its roots in real buildings whose traces survive: Nebuchadnezzar's palace complex. It does not say the gardens themselves have been found.

What has been measured at Babylon and the Hanging Gardens (Iraq) in peer-reviewed studies?

Walls, gates and temples: UNESCO lists two rings of city walls, plus gates, palaces and temples. They include the ziggurat (stepped temple tower) called Etemenanki. Mostly still buried: UNESCO says 85 percent of the site has not been dug. Not in the king's records: The gardens are usually credited to King Nebuchadnezzar II in the 6th century BC. Dalley notes they are not named in the many written records from his reign. A large German team dug his palaces for over 25 years and did not find them. Nothing confidently found: Reade (2000) writes that no remains of such a building have been confidently found at Babylon. He adds that people took bricks from the ruins for thousands of years. Only the foundations of many big buildings are left. Babylon is a huge ruined city in Iraq. Kings such as Hammurabi and Nebuchadnezzar ruled from it. Greek and Roman writers listed its Hanging Gardens among the Seven Wonders of the World. Yet no trace of the gardens has been confidently found there.
