Neath Castle (Castell Nedd) is located in the town centre of Neath, Wales ( Castell-nedd, Cymru). It stands in a strategic place that guards an important river crossing. The site is that of a twelfth century Norman castle that possibly replaced an earlier fortification. The castle was persistently attacked by the Welsh and after being burnt by Llewellyn ap Iorwerth, it was rebuilt in stone. It was sacked again in the fifteenth century and the gatehouse seen today was built. Sections of the curtain wall also remain. The location of the castle is in the centre of Neath (Welsh: Castell-nedd).
