Castell Nonni is a motte-and-bailey castle located in Carmarthenshire, Wales, and represents early medieval military architecture of the Norman period. The site comprises a substantial earthen mound typical of 11th and 12th-century fortifications, constructed to command local territory during the Norman expansion into South Wales. The castle's strategic position reflects the pattern of Norman settlement and defence in the region, though documentary evidence regarding its specific founding date and historical use remains limited. The earthwork survives as an important archaeological monument demonstrating the defensive strategies employed by Norman lords establishing control over Welsh territories.
