Castell Llansteffan is a medieval castle occupying a prominent coastal promontory near the village of Llansteffan in Carmarthenshire, South Wales. The site was first fortified in the early Norman period, with the castle developing through the twelfth and thirteenth centuries as a significant stronghold in the region. The surviving remains comprise an inner ward with stone fortifications and an outer bailey, reflecting the castle's evolution from an early motte-and-bailey structure to a more elaborate stone fortress. The castle's strategic position overlooking the Towy estuary made it an important defensive site controlling access to the river valley during the medieval period.
