Political center of Ulster during pre-Christian and early Christian times.
Now called Navan Fort, it is located near the town of Armagh in Northen Ireland. It was the seat of the semihistorical king Conchobar , a subject of the medieval Irish tales of the Ulster cycle along with Cú Chulainn and other great warriors. St. Patrick established his base near Emain Macha, and it is still the primatial see of both the Roman Catholic and Protestant churches in Ireland.
