Castell-Du is a medieval motte-and-bailey castle situated near Sennybridge in Breconshire, Wales, serving as a defensive stronghold in the Welsh Marches during the Norman period. The monument consists of an earthen mound with associated bailey, typical of early medieval fortification design, and reflects the pattern of Norman expansion into South Wales during the twelfth century. Its strategic location within the upland terrain of Breconshire indicates its role in controlling movement through this border region, though like many similar structures, it saw limited occupation relative to its military potential. The site remains substantially as earthworks, preserving the fundamental character of its medieval defensive design without significant structural remains above ground level.
