Tell Tuneinir is situated on the eastern bank of the Khabur river, 15 km (9.3 mi) southeast of Al-Hasakah,[1] and have an area of 40 hectares (99 acres).

[2] Bronze Age artifacts found include different kinds of pottery, bone tools, animals figurines made of clay depicting sheep, goats, and horses, and two clay ; one has the shape of astragulus and the other the shape of a robe, thus they relate to animal products and textile manufacturing.

[2] The site's role as an agricultural settlement is apparent by the existence of decorated sherds depicting animals grazing.

[4] The ala prima nova Diocletiana, an equites sagittarii indigenae ("indigenous horse archers") unit, was stationed in the region between Tell Tuneinir, now named Thannuris, and Horaba (modern Tell Ajaja).

[9] Eventually Justinian's efforts were successful, and the town became a "truly formidable" fortress, to protect the region from Saracen raids.
