During his very long reign, Nebuchadnezzar II, the son and immediate successor of the founder of the Neo-Babylonian Empire (Nabopolassar), sponsored building activities in at least thirteen Babylonian cities. The transformation of Babylon into an imperial megacity was by far his greatest achievement. In his capital, building on what his father had started, Nebuchadnezzar is known to have worked on no less than thirteen temples, as well as the massive ziggurat; renovated one palace and constructed an additional two royal residences; completed and expanded the inner and outer city walls, together with their embankment walls; redug and improved at least one major canal; and raised and repaved the Processional Way. Presumably, he did more at Babylon, which he transformed in an "object of wonder," than what is presently known from available cuneiform sources and from the archaeological record. This Neo-Babylonian ruler was undoubtedly one of the most active Mesopotamian builders. From extant textual sources, mostly royal inscriptions, Nebuchadnezzar's main building projects are:

Collingwood, Plan of the supposed ruins of Babylon.
In addition, Nebuchadnezzar's inscriptions record that he had at least two other walls (or earthen ramparts with baked-brick sides) constructed. The first stretched from Babylon to Kish and then from Kish to Kar-Nergal and then rot the Tigris river. The second — which has been partial excavated and surveyed — was built just north of Sippar and it also ran the entire stretch between the Tigris and Euphrates Rivers, from Sippar to Up. The latter has been partial excavated and surveyed. An Akkadian inscription written on clay cylinders records the following:
Perhaps in connection with this work, or the rebuilding of the Nergal temple Emeslam, this Neo-Babylonian king had a water-filled moat (Akkadian hirītu) dug around the city of Cutha.
Moreover, archaeological evidence from other sites have yielded evidence for Nebuchadnezzar undertaking construction in those Babylonian cities. These include Abu Qubur (not to be identified with ancient Durbissu), Hursagkalama (modern Tell Ingharra), Jemdet Nasr (or its surroundings), Kissik (modern Tell al-Laḥm), Seleucia, and Sippar-Anunītu (modern Tell ed-Der).
