Azov

Azov , formerly known as Azoff,
is a town in Rostov Oblast, Russia, situated on the Don River just 16 kilometers from the Sea of Azov, which derives its name from the town. Population: 82,937 ; 82,090 ; 80,297 .
The mouth of the Don River has always been an important commercial center. At the start of the 3rd century BCE, the Greeks from the Bosporan Kingdom founded a colony here, which they called Tanais . Several centuries later, in the last third of 1st century BCE, the settlement was burned down by king Polemon I of Pontus. The introduction of Greek colonists restored its prosperity, but the Goths practically annihilated it in the 3rd century. The site of ancient Tanais, now occupied by the khutor of Nedvigovka, has been excavated since the mid-19th century.
