Bynea was originally the grassing lands for the
Romans, who built their fort in
Loughor. The Yspitty area of Bynea was also a port for the ferry crossing of the
River Loughor. It wasn't until the middle of the 19th century when the first
Loughor Bridge was built that the Banc Y Spitty port was closed and the ferry from Loughor to Bynea out of use. Bynea was the name given to the areas east of the village centre and the lands used by the Romans. Where the old and central part of the village today, was originally called Cwm-Felin.This is still visible by the fact of the Cwmfelin Road running through Bynea to nearby
Llwynhendy. It was called this after the mill that is still visible today from Heol Saron. This was an agricultural area until the turn of the twentieth century, when it became heavily industrialised with
coal mines and
steelworks. Bynea runs into the village of
Llwynhendy, and between the two there are four places of worship, and a number of pubs. ==Welsh language==
