River Afan
The River Afan (Welsh: Afon Afan) is a river in Wales whose valley formed the territory of the medieval Lords of Afan. The Afan Valley encompasses the upper reaches of the river. The valley is traversed by the A4107 road. Settlements in the area include Cwmafan, Pontrhydyfen and Cymmer. The town of Aberavon, whose name in Welsh Aberafan means ‘mouth of the Afan’, grew up on the banks of the river and was later subsumed by town of Port Talbot.
Multiple hypotheses exist regarding the origin of the river’s name. One suggestion is that it is from “A-Ban” meaning “from the heights” due to its comparatively quick descent from hills to the sea. (Compare to the ‘Ban’ in “Bannau Brycheiniog”, the Brecon Beacons).[1] However, such a name would be very unusual for a river. It is not parallelled elsewhere, and does not fit in with the pattern of Welsh stream and river nomenclature in general. A. D. Mills believes the river derives ultimately from a personal name.
The Afan rises on the northern slopes of Mynydd Llangeinwyr to the east of Blaengwynfi, and flows in a generally south-westerly direction roughly parallel to the River Neath with which it shares its western watershed.
The river passes the Afan Argoed Country Park in its middle reaches. It converges with the river Pelenna at Pontrhydyfen. From here it turns southward towards Port Talbot.
To aid the construction of the docks at Port Talbot, the river was impounded and a diversion channel built that now forms the lower reaches of this river. There are two weirs in this final tidal reach of the Afan; Greenpark Weir at the upstream tidal limit, which has been reconstructed in 2017 and provides headwaters for the dock feeder channel that approximately follows the river’s original route, and Newbridge Weir, which is the most downstream weir, presents a barrier to fish passage and is in a poor state of repair.
A motte and bailey castle stood on the banks of the river as it passed through Aberavon during the medieval period. No remains are now visible above ground, but the site of the castle is commemorated in local street names.
