Tell Deir Situn was an archeological site 45 km north-west of Nineveh, located in Iraq. The construction of a new dam northwest of Mosul, Iraq, led to a 1985 British Museum team unearthing two Hellenistic ruins called Tell Deir Situn and Grai Darki The dig at Tell Deir Situn produced large amounts of pottery, a bronze Assyrian fibula, and a Seleucid era coin.
The building of a new dam on the Tigris river, approximately 40 km northwest of Mosul, Iraq, threatened hundreds of archaeological sites spanning almost to the border with Syria and Turkey, providing the British Museum with the chance to get involved in Mesopotamian archaeology once more. The Iraqi government asked a number of international delegations to take part in order to make sure that as many of these sites were examined before being submerged under the lake that would form behind the dam. The British Archaeological Expedition to Iraq was a major player in this rescue effort.
Located close to the settlement of Deir Situn, east of the old Mosul-Zakho route and north of the road to Alqosh, lies Tell Deir Situn, a low mound encircled on three sides by a small wadi.
The Tell Deir Situn mound was roughly 72 m by 100 m. Seventeen 4 m square trenches were dug, revealing large stone wall-footings of a substantial building on the west side of the mound. The buildings were preserved up to a maximum height of six stone courses. The building's dimensions were 17.70 by 5.55 meters, and it had some buttresses on the outside faces in addition to projecting walls on two of its sides. There were found to be two building phases, the earlier of which had mostly disappeared. Although the building's purpose is unclear, it may have served as a "police-post" or something similar.
A copious amount of pottery was found within the building. It featured shapes painted in red or black as well as fish plates and bowls that are typical of the Hellenistic era. A variety of floral motifs were stamped on a portion of the sherds. The collection of Hellenistic ceramics, included a fishplate, a bowl with in-turned rim, a bowl with out-turned rim, a plate with the rolled rim, jars, stamped sherds, and pipe lamps, have been found at the site. A 'fish-tail' pottery lamp, a collection of oval-stamped terracotta loomweights, and a terracotta figure depicting a man with a cloak draped over his shoulder and a belted tunic are among the other discoveries.
The finding of a coin connected to the most recent phase of the building confirmed the Hellenistic date of the site. The coin dates to the Seleucid ruler Alexander Balas's rule (150–145 B.C.). Minted in Antioch, the reverse shows an Apollo with a bow and arrow.
There was no indication of Assyrian habitation at either site, although in Tell Deir Situn, a piece of a bronze fibula shaped like a lady with her hands clasped beneath her bust was found on the ground. Due to this finding made in the fall of 1985, John Curtis states it is evident that this fibulae is Assyrian from the 7th century bce despite its differences from other fibulae that have been found.
