Newport Castle is a medieval fortification situated in Newport, Pembrokeshire, Wales. The castle was constructed in the early fifteenth century, likely begun around 1435, by William ap Thomas, a powerful Welsh nobleman of the period. The structure comprises a compact stone gatehouse with flanking towers and curtain walls, designed to protect the settlement and control access to the River Nevern estuary. As one of the few surviving castles built by a Welsh lord during the late medieval period, Newport Castle represents an important example of indigenous Welsh military architecture constructed after the Edwardian conquest of Wales.
