Hanging Gardens of Babylon
Thereafter, successive Assyrian emperor-monarchs, such as Shalmaneser III, Adad-nirari III, Tiglath-Pileser III, Shalmaneser V and Sargon II, continued to expand the city. Around 700 BC, King Sennacherib made Nineveh Assyria's new capital. Immense building work was undertaken, and Nineveh eclipsed Babylon, Kalhu and Aššur in size and importance, making it the largest city in the world. A number of scholars believe the Hanging Gardens of Babylon were in fact at Nineveh.
