Castell Llain-Fawr is a motte-and-bailey castle situated in Pembrokeshire, Wales, which dates to the Norman period following the late eleventh-century conquest and settlement of south Wales. The site comprises a substantial earthwork mound typical of early Norman fortifications, designed to provide defensive control over the surrounding landscape during a period of intensive castle-building by Norman lords establishing their authority in the region. The castle's strategic location reflects the broader pattern of Norman military expansion throughout Pembrokeshire in the decades following 1066, when such motte-and-bailey structures served as the primary form of fortification before the development of stone castles. Today the monument survives as an important archaeological and historical record of Norman military architecture and settlement strategy in medieval Wales.
