Archaeology

Akarçay Tepe 

Akarçay Tepe is a small, flattish, oval-shaped mound located west of the village. Along with nearby Mezraa Teleilat, it is one of the oldest known settlements in the Euphrates basin. It was first identified in 1989 by a team led by G. Algaze, who found Paleolithic flint tips and drill bits were found before any excavation took place. In 1998, a team led by Nur Balkan-Atlı surveyed the site; they then began excavation in 1999. In 2001, M. Özdoğan and N. Karul conducted further research at Akarçay Tepe and dated various artifacts found here to the Ubaid period, Late Chalcolithic, Iron Age, Neolithic, Pottery Neolithic, and Pre-Pottery Neolithic.

The tepe consists of 7 layers, with the top being a "mixed" layer and the others being numbered Phase I through VI. The youngest and uppermost layer, Phase I, has been radiocarbon dated to  6225–6015 BCE, in the Copper Age. Below it is Phase II, which is dated to  6455–6200 BCE, spanning the end of the Pottery Neolithic up to the beginning of the Halaf period in the early Chalcolithic. Phase III is a "transitional" phase dated to  7185–6515 BCE. Below it is Phase IV, which is dated to  7595–7145 BCE, in the terminal Pottery Neolithic. Phase V is dated to  7940–7610 BCE, in the late Pottery Neolithic. Phase VI, the bottom layer, has not been radiocarbon dated but is estimated to belong to the middle Pre-Pottery Neolithic.

Another site, known as Akarçaytepe 2, is located 250 m northeast of Akarçay Tepe, on both sides of the Su Dere. This is 300 m north of Akarçay village. It was first identified by G. Algaze's team in 1989, who identified finds from the Ubaid and Uruk periods of the Chalcolithic, along with the Middle Bronze Age.

Akarçay Höyük 
Akarçay Höyük is a medium-sized mound, measuring 180×160 m, located 900 m south of Akarçay village. In Algaze's team's 1989 survey, pottery shards from the Early and Middle Bronze Age, Hellenistic period, Roman period, and Byzantine period were found here. Salvage excavations were conducted in 1998 under Y. Mergen and A. Deveci, and these excavations uncovered Early Bronze Age "metallic ceramics" samples, similar to ones found at Hayaz and Samsat. Then in 2001 a team led by M. Özdoğan and N. Karul uncovered Late Neolithic, Late Chalcolithic, and Byzantine-era artifacts. There is also a 13th–14th century CE cemetery at the site.

Other sites 
Gre Virike: a small mound, measuring 60×70 m in diameter and 15 m in height, located near the village. First identified in 1989 by G. Algaze and then surveyed in 1998 by A.T. Ökse, who found artifacts dated to the Late Chalcolithic and Early Bronze Age. Ökse then did a salvage excavation here in 1999 and concluded that the settlement at Gre Virike served as a cult center for surrounding villages during the Early Bronze Age. Özdoğan and Karul also did surface examinations here in 2001 and found various Early through Late Chalcolithic as well as Early and Middle Bronze Age.
