Llanblethian Castle is a medieval fortress located in the Vale of Glamorgan, Vale of Glamorgan, Wales, with origins in the Norman period. The castle comprises a motte-and-bailey earthwork, characteristic of early Norman defensive architecture in South Wales, with substantial surviving earthen ramparts that define its layout. The site was likely established in the twelfth century as part of the Norman consolidation of Glamorgan, serving as a strategic stronghold in the region. The castle's earthwork fortifications, though lacking substantial stone structures today, represent an important example of early medieval military architecture in Wales and remain a significant archaeological monument protected under Cadw's Schedule of Ancient Monuments.
