Bālis

Balis, also known as Barbalissos and Barbalissus (Latin), was an ancient and medieval fortress on the Euphrates River near the ruins of the still more ancient Emar. It is particularly known for the 253 Battle of Barbalissos, where the Roman army was defeated by Sassanid Persia. The fortress town's own ruins are located at the modern Qala'at Balis in the Aleppo Governorate of northern Syria.
