Nannar had a temple at Ur, called E-gišširgal, and one at Harran, known as E-ḥulḥul. Ur was the oldest of the two temple cities. Its history may possibly reach back to 4000 B. C. Ur held a position in southern Babylonia similar to that held by Nippur in northern Babylonia, but was not so old as Nippur. Ur was the religious centre in the south with Nannar as the state god, as Nippur was the religious centre in the north with Bêl as the state god. When the states of the south and the north were united under Ḥammurabi, Babylon, becoming the religious capital of the south and the north combined, the state lustre of the god of Babylon naturally came to dim the glory of the god of Ur as well as that of Nippur. Harran, situated on the Euphrates in the northern part of Assyria, never figured in state power, and was prominent only because of the importance of the events that centered there, on the road between the east and the west. Nabonidus, the last Semitic Babylonian king (555-538 B. C.) was an enthusiastic devotee of the moon-god. He tells us what Ašurbânipal did to the temple of the moon-god at Mugheir. In speaking of that temple, he calls it the house of Sin which Ašurbânipal, king of Assyria, son of Esarhaddon, king of Assyria had built. Nabonidus himself rebuilt both the temples of the moon-god, the temple of E-gišširgal at Ur and the temple of E-ḥulḥul at Harran, and he gives us a description of the rebuilding of both. We also have two prayers of Nabonidus addressed to the moon-god, one addressed to him at E-gišširgal, the other addressed to him at E-ḥulḥul (see I R. 68, Col. I, 6 ff. and V R. 64, Col. I, 8 ff.). The temple ruins of E-gišširgal have been well uncovered. The temple is of rectangular form, the four corners turned towards the four cardinal points of the compass. The platform of the base is at the level of the roofs of the houses, made of solid masonry of bricks and reached by steps at the end. On the platform are two stagings, also of solid masonry reached by steps at one end. On the second staging is a shrine of the moon-god. In sculpture he appears as an old man with long beard and dressed in royal robes. He wears a hat and in the scene there is always a thin crescent (see Clercq, Vol. I, Plates X-XV). Loftus and Taylor both give drawings of the temple of E-gišširgal (see TR. p. 127 and JRAS. XV, p. 260.) The ruins of the temple of the moon-god at Harran have not yet been uncovered to the extent that the plan of the temple can be laid before us.
