 It is the Roman campaigns of conquest that are most widely known, due to the spirited but unsuccessful defence of their homelands by two native tribes, the Silures and the Ordovices.Aside from the many Roman-related finds along the southern coast, Roman archaeological remains in Wales consist almost entirely of military roads and fortifications.On the eve of the Roman invasion of Wales, the Roman military under Governor Aulus Plautius was in control of all of southeastern Britain as well as Dumnonia, perhaps including the lowland English Midlands as far as the Dee Estuary and the River Mersey, and having an understanding with the Brigantes to the north.
