Arcadius solidus, from Mediolanum mint, 400s.

Mediolanum, the modern Milan, appears to have been founded by the Celts of Northern Italy around 600 BC and was conquered by the Romans around 222 BC, who may have given it its Latin-Celtic name (the name element -lanum is the Celtic equivalent of -planum 'plain'). In the 4th century AD, at the time of the bishop St. Ambrose and emperor Theodosius I, the city became for a short time the capital of the Western Roman Empire.
