Kar-Tukulti-Ninurta was a new foundation about 3 km (1.9 mi) north of Assur, which was the old capital of the Assyrian empire.
In the western part, near to the river, a temple was excavated for the Assyrian main deity, Ashur.
The city was largely abandoned after the death of king Tukulti-Ninurta I with minor occupation continuing through the Neo-Assyrian period.
A full excavation report appeared only in 1985 Work at the site was resumed in 1986 with a survey by a team from the German Research Foundation led by R. Dittman.
