Castell Nonni is a motte and bailey castle situated in Carmarthenshire, Wales, that dates to the Norman period following the late eleventh-century conquest and settlement of South Wales. The site consists of a substantial earthen mound characteristic of early Norman fortification strategy, which would have originally been crowned by timber defensive structures. The castle represents the pattern of Norman military occupation across Carmarthenshire, part of the broader defensive network established to consolidate control over the conquered Welsh territories. Though now reduced to its earthwork remains, the monument preserves evidence of the castle's original scale and engineering, recorded under the Cadw archaeological record as SAM CM102.
