Carmarthen Castle is a medieval fortress founded in the late eleventh century following the Norman conquest of South Wales, situated strategically on a hilltop overlooking the River Tywi in the county town of Carmarthen. The castle comprises a motte-and-bailey earthwork surmounted by later stone structures, including a substantial round tower and curtain walls that were progressively strengthened during the twelfth and thirteenth centuries. As one of the principal Norman strongholds in Carmarthenshire, it served as an administrative centre and military garrison, controlling the surrounding region and the important river crossing. The surviving masonry, though substantially ruined, testifies to the castle's significance as a defensive and political seat during the medieval period, though it gradually declined in importance following the annexation of Wales in the sixteenth century.
