Aontroim · Ulster
People have lived in Antrim for about nine thousand years: at Mount Sandel, on the east bank of the Bann at Coleraine, hunter-gatherers were settled around 7000 BC, one of the earliest known sites in Ireland. In the early Middle Ages the south of the county belonged to the Ulaid kingdom of Ulidia and the north to Dál Riada, a kingdom that reached across the sea into what is now western Scotland; the Dál nAraide and the Cruthin held land here too. Vikings raided the coast between the 8th and 11th centuries.
