Perched on a cliff edge overlooking the River Wye, you can see why this spot was chosen as the location for a fort by its original builders – and why it was later occupied by Roman invaders.
Yn sefyll ar ymyl clogwyn uwchben Afon Gwy, hawdd yw gweld pam y dewisodd yr adeiladwyr gwreiddiol y llecyn hwn ar gyfer eu caer – a pham y cafodd ei meddiannu’n ddiweddarach gan oresgynwyr Rhufeinig.
