Visitors walk through the newly renovated Ishtar Gate in ancient Babylon, some 100 kms south of Baghdad, on November 27, 2008. Fragments of bricks, engraved with cuneiform characters thousands of years old, lie mixed with the rubble and sandbags left by the US military on the ancient site of Babylon in Iraq. Archaeologists say a year of terracing work and 18 months of military presence, with tanks and helicopters, have caused irreparable damage to one of the cradles of civilisation.
