Overview

History & significance

Castell-Du is a medieval motte-and-bailey castle situated near Sennybridge in Breconshire, Wales, constructed during the Norman period following the Anglo-Norman advance into South Wales. The monument comprises a substantial earthen motte with an adjoining bailey, representing a typical form of early medieval fortification employed to secure territorial gains and control local populations. The castle's strategic position within the Brecon Beacons region reflects its role in the wider Norman military campaign and settlement of Wales during the eleventh and twelfth centuries. Though the castle appears not to have developed into a stone fortress and was eventually abandoned, its earthwork remains provide important archaeological evidence of Norman military strategy and settlement patterns in medieval Wales.
