Tell Barri (ancient Kahat) is a tell, or archaeological settlement mound, in north-eastern Syria in the Al-Hasakah Governorate.

In the Middle Bronze IIA, the eighteenth century BC, the city now known as Kahat is attested from the palace archives of Mari.

By the 15th century BC, the town emerged as a religious centre when the Hurrian kingdom of Mitanni established itself in the region.

[7] The temple to the Storm god Teshub in Kahat is specifically mentioned in the Shattiwaza treaty of the fourteenth century BC.

Suppiluliuma entered a treaty with Shattiwaza (r. 1330-1305 BC), son of Tushratta, making the remnants of the Kingdom of Mitanni a vassal of the Hittites, and a buffer-state between Hatti in the west and Assyria in the east.

[9] In the Neo-Assyrian Empire period a palace was built by the Assyrian king Tukulti-Ninurta II (891-884 BC) in Kahat.

The town lived on after the end of the Assyrian empire in the seventh century BC as a part of Achaemenid Assyria.

In 1980 excavations were begun by a team of Italian archaeologists from the University of Florence, led by Paolo Emilio Pecorella and Mirjo Salvini.

[15] Also found were the remains of the royal palace of Neo-Assyrian ruler Tukulti-Ninurta II (Area J), and the Great Circuit Wall that surrounds the tell and dates to the Parthian period.
