The Euphrates (i//; Arabic: الفرات: al-Furāt, Hebrew: פרת: Prat, Turkish: Fırat, Kurdish: Firat) is the longest and one of the most historically important rivers of Western Asia. Together with the Tigris, it is one of the two defining rivers of Mesopotamia. Originating in eastern Turkey, the Euphrates flows through Syria and Iraq to join the Tigris in the Shatt al-Arab, which empties into the Persian Gulf.
Dura-Europos (Greek: Δοῦρα Εὐρωπός), also spelled Dura-Europus, was a Hellenistic, Parthian and Roman border city built on an escarpment 90 m above the right bank of the Euphrates river. It is located near the village of Salhiyé, in today's Syria.
Dura-Europos is extremely important for archaeological reasons. As it was abandoned after its conquest in 256–7, nothing was built over it and no later building programs obscured the architectonic features of the ancient city. Its location on the edge of empires made for a co-mingling of cultural traditions, much of which was preserved under the city's ruins. Some remarkable finds have been brought to light, including numerous temples, wall decorations, inscriptions, military equipment, tombs, and even dramatic evidence of the Sassanian siege during the Imperial Roman period which led to the site's abandonment.
