Castell Llansteffan is a medieval castle occupying a commanding hilltop position overlooking the River Taf estuary in Carmarthenshire. The fortress comprises substantial stone fortifications arranged around a central bailey, with evidence of Norman construction dating from the twelfth century, though the site may have earlier medieval origins. The castle's strategic location controlling access to the river crossing made it significant in the context of Anglo-Norman penetration into South Wales during the medieval period. Substantial portions of the stone defences remain visible today, including sections of curtain walling and earthwork ramparts that testify to its former importance as a defensive stronghold.
