Babylon
During the reign of Sennacherib of Assyria, Babylonia was in a constant state of revolt,  It was only pacified by the complete destruction of the city of Babylon. In 689 BCE, its walls, temples and palaces were razed, and the rubble was thrown into the Arakhtu, the river on the south side of the city.  This act shocked the religious conscience of Mesopotamia.  After the murder of Sennacherib by two of his sons, his successor Esarhaddon hurried to rebuild the old city.  He was crowned there, and it was where he lived for part of the year.
