A team of German and Kurdish archaeologists has uncovered a 3400-year-old Mittani Empire city once located on the Tigris River. The Bronze Age city resurfaces after the waters of the Mosul reservoir fell rapidly because of the extreme drought in Iraq.
The extensive city with a palace and several large buildings could be ancient Zakhiku–believed to have been an important center in the Mittani Empire, which controlled large parts of northern Mesopotamia and Syria (ca. 1550-1350 BC).
Bronze Age city resurfaces
Large amounts of water have been drawn from the Mosul reservoir since December 2021. This has led to the reappearance of a Bronze Age city that had been submerged decades ago without any prior archaeological investigations. It is located at Kemune in the Kurdistan Region of Iraq.
This unforeseen event put archaeologists under sudden pressure to excavate and document at least parts of this large, important city as quickly as possible before it was resubmerged.
Kurdish archaeologist Dr. Hasan Ahmed Qasim, chairman of the Kurdistan Archaeology Organization, and the German archaeologists Jun.-Prof. Dr. Ivana Puljiz, University of Freiburg, and Prof. Dr. Peter Pfälzner, University of Tübingen, spontaneously decided to undertake joint rescue excavations at Kemune. These took place in January and February 2022 in collaboration with the Directorate of Antiquities and Heritage in Duhok (Kurdistan Region of Iraq).
A team for the rescue excavations was put together within days. Funding for the work was obtained at short notice from the Fritz Thyssen Foundation through the University of Freiburg. The German-Kurdish archaeological team was under immense time pressure because it was not clear when the water in the reservoir would rise again.
Massive fortification, multi-storey storage building, industrial complex
Within a short time, the researchers succeeded in largely mapping the city. In addition to a palace, which had already been documented during a short campaign in 2018, several other large buildings were uncovered – a massive fortification with wall and towers; a monumental, multi-storey storage building; and an industrial complex.
“The huge magazine building is of particular importance because enormous quantities of goods must have been stored in it, probably brought from all over the region,” said Puljiz.
“The excavation results show that the site was an important center in the Mittani Empire,” added Qasim.
The research team was stunned by the well-preserved state of the walls – sometimes to a height of several meters – despite the fact that the walls are made of sun-dried mud bricks and were under water for more than 40 years. This good preservation is due to the fact that the city was destroyed in an earthquake around 1350 BC, during which the collapsing upper parts of the walls buried the buildings.
Ceramic vessels with more than 100 cuneiform tablets
Of particular interest is the discovery of five ceramic vessels that contained an archive of over 100 cuneiform tablets. They date to the Middle Assyrian period, shortly after the earthquake disaster struck the city. Some clay tablets, which may be letters, are even still in their clay envelopes. The researchers hope this discovery will provide important information about the end of the Mittani-period city and the beginning of Assyrian rule in the region.
“It is close to a miracle that cuneiform tablets made of unfired clay survived so many decades underwater,” said Pfälzner.
To avert further damage to the important site by the rising water, the excavated buildings were completely covered with tight-fitting plastic sheeting and covered with gravel fill as part of an extensive conservation project funded by the Gerda Henkel Foundation. This is intended to protect the walls of unbaked clay and any other finds still hidden in the ruins during times of flooding. The site is now once more completely submerged.
