Fort and Minor Settlement
Prestatyn lies five miles north of the main east-west highway from the legionary fortress at Deva (Chester) into North Wales. It is very likely that a Roman branch-road linked Prestatyn with the main highway near St Asaph, and continued south through the territories of the Deceangi along the valley of the River Clwyd, to the fort at Ruthin and the Berwyn Mountains, the realm of the Ordovices. There is some evidence that another road followed the coast south-east to Deva via the silver/lead mines at Pentre, though this route may have been supplied by sea.
