River Afan

The River Afan (generally anglicized as Avon, and sometimes historically as Avan) is a river in southwest Wales whose river valley formed the territory of the medieval Lords of Afan. The town of Aberavon grew up on the banks of the river, and was later subsumed by the larger centre of population known as Port Talbot. The political constituency still retains the name Aberavon (on the Afan) however.
