Neath Castle Neath Castle (Welsh: "Castell Nedd" ) is a Norman castle located in the town centre of Neath, Wales. Its construction was begun by Robert, Earl of Gloucester, the nominal Lord of Glamorgan, at a date estimated between 1114 and 1130. It is also referred to as "Granville's Castle", after Richard I de Grenville (or Granville or Glanville; died post 1142), Lord of Neath, who has also been credited with its construction. The town of Neath takes its Welsh name, "Castell-nedd", from the castle.
