Roman road Caernarfon-Tomen-y-mur, part of Margary RR68 Caernarfon-Caer Gai (Nprn303421); visible as terrace/causeway to south of NGR, thereafter speculative.
Road observed, 3.0-3.6m wide, of pebbled surface/subsurface, upon stone block foundation; possible ditch to west (Kelly 1992).Road could not be traced beyond this point (Longley 1996, 215), casting doubt on its identity as a long distance route.
