Tomen yr Allt Castle Mound is a motte dating from the Norman period in Wales. The site comprises an earthen mound typical of early medieval fortifications, constructed to command the surrounding landscape and serve defensive purposes during the period of Norman expansion into Welsh territories. Located within the jurisdiction of Cadw, it represents the material evidence of military occupation and control in the medieval Welsh borderlands. The mound's form and construction reflect the strategic importance of the location during the twelfth and thirteenth centuries, when such fortifications were instrumental in establishing Norman authority across the region.
