Sippar (Sumerian Zimbir; modern Tell Abu Habbah) is the principal Babylonian cult center of the sun-god Šamaš and his wife Aya. Because this northern Babylonian city — which is located on the east bank of the Euphrates River, approximately 70 km north of Babylon — was very important and influential, its city wall Baduldua (also called Badullisâ), its principal temple Ebabbar, and its ziggurat Ekunankuga are included in first-millennium-BC lists of temples and ziggurats. In a text that enumerates religious structures hierarchically, the so-called "Babylonian Temple List," Ebabbar is ranked second, after Ekur (the temple of the god Enlil at Nippur) and before Esagil (the temple of the god Marduk at Babylon).

Construction work on Ebabbar and Ekunankuga are well attested in late Neo-Assyrian (721–612 BC) and Neo-Babylonian (625–539 BC) royal inscriptions.
