The use of the title continued during the reigns of Atal-Shen's successors, Tupkish and Tish-Atal, who ruled only in Urkesh. The Akkadians under Naram-Sin incorporated Nagar firmly into their empire. The most important Akkadian building in the city is called the "Palace of Naram-Sin", which had parts of it built over the original Eye Temple. Despite its name, the palace is closer to a fortress, as it was more of a fortified depot for the storage of collected tribute rather than a residential seat. The palace was burned during Naram-Sin's reign, perhaps by a Lullubi attack, and the city was burned toward the end of the Akkadian period c. 2193 BC, probably by the Gutians.
