City of Dura-Europos

[Source]

Dura-Europos, 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. 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. 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.
