A bilingual introduction to the 8th century earthwork on the border between Wales and England. Constructed from a mixture of earth, mud, stones and branches and extending from the Dee Estuary in the north to the Severn Estuary in the south, Offa's Dyke has proved to be a physical, geographical and cultural boundary between England and Wales.

Cyflwyniad dwyieithog yn llawn ffeithiau difyr a lluniau lliw am Glawdd Offa. Adeiladwyd y clawdd gwreiddiol nôl yn yr wythfed ganrif allan o fwd, baw, pridd, coed a cherrig gan Frenin oedd â chryn dipyn o bŵer ac awdurdod. Ers canrifoedd, mae Clawdd Offa wedi cadw Cymru a Lloegr ar wahân - dwy wlad, dwy iaith, dau ddiwylliant a dwy ffordd o fyw.
