Urukagina's championship of Ningirsu's rights is reflected, not only in his reforms, but also in the buildings he erected during his reign. Thus we find it recorded that, in addition to his great temple E-ninnû, he built or restored two other temples in his honour, his palace of Tirash, and his great storehouse. Other temples were erected in honour of Bau, his wife, and of Dunshagga and Galalim, two of Ningirsu's sons, the latter of whom is first mentioned in Urukagina's texts. To Khegir, one of the seven virgin daughters of Ningirsu, he dedicated a shrine, and he built another in honour of three of her sisters, Zarzari, Impae, and Urnuntaea; a third was dedicated to Ninsar, Ningirsu's sword-bearer. It may thus be inferred that Urukagina's building operations were mainly devoted to temples and shrines of the city-god Ningirsu, and to those dedicated to members of his family and household. Like Eannatum and Entemena, he also improved the water-supply of the city, and cut a canal, or more probably improved an old one, for bringing water to the quarter of the city named Ninâ. In connection with it he constructed a reservoir, with a capacity of eighteen hundred and twenty _gur_, which he made, he tells us, "like the midst of the sea."[51] The small canal of Girsu he also repaired, and he revived its former name, "Ningirsu is prince in Nippur."[52] This furnishes another instance of his policy of restoring to Ningirsu honours and privileges of which he had been deprived. The reference to Nippur is of interest, for it suggests that Urukagina maintained active relations with the central cult of Sumer and the north, an inference confirmed by his rebuilding of Enlil's temple in Lagash, which had been previously built by Entemena.
Allusions to cities other than Lagash and its component parts in Urukagina's inscriptions are few, and those that do occur fail to throw much light upon the relations he maintained with other city-states. A small object of clay in the form of an olive[53] has been found, which bears the votive inscription: "Ningirsu speaks good words with Bau concerning Urukagina in the temple of Erech,"--a phrase that seems to imply a claim on the part of Lagash to suzerainty over that city. Another votive object of the same class mentions the fortification of the wall of E-babbar,[54] but the reference here is probably not to the famous temple of the Sun-god at Larsa, but to his smaller temple of this name, which stood in Lagash and was afterwards desecrated by the men of Umma. The only other foreign city mentioned in Urukagina's inscriptions is Umma itself, whose relations to Lagash in the reigns of Enannatum I. and Entemena are briefly recorded.[55] The text of the passage is broken, but we may surmise that the short summary of events was intended to introduce an account of Urukagina's own relations with that city. We may note the fact, which this reference proves, that the subsequent descent of the men of Umma upon Lagash and their capture and sack of the city were the result of friction, and possibly of active hostility, during at least a portion of Urukagina's reign.
