Nikōnion was founded in the second half of the 6th century BC by colonists from
Miletus. On the opposite bank of the river other Milesian colonists had already founded
Tyras. The city was founded at a time when many
nomadic tribes were beginning to settle in the areas north of the
Black Sea. The Greeks settled in this area because of the plentiful fishing and the opportunity to trade with these barbarian settlers. Stone construction in the city began in the 5th century. At the turn of the 3rd-2nd centuries BC, the city was destroyed, an event which was associated with the Macedonian commander
Zopyrion, associate of
Alexander the Great. In the 1st century BC, the size of the city increased from the previous period. Nikōnion was abandoned permanently in the middle of the third century AD when the area was invaded by the
Goths during the
Great Migrations. ==Archaeological excavations==
