Ffos Toncenglau cross ridge dyke is a prehistoric linear earthwork located in Wales, constructed to block passage along a ridge or natural routeway. The monument consists of a ditch and bank formation typical of cross ridge dykes, defensive structures built during the later prehistoric period to control movement across the landscape and protect communities or territorial boundaries. Such dykes are generally dated to the Iron Age, though some may have been constructed or maintained during earlier periods. The site is recorded in the Cadw Monuments Register under the reference GM118 and represents an important example of Iron Age defensive and territorial planning in the Welsh landscape.
