Surrounded by the ocean on three sides, Dunseverick was also a key ancient site in Ireland, one of the royal roads from Tara, seat of the Kings of Ireland is believed to have run to here as well as Lissanduff at Portballintrae.  The site was originally founded by Sobairce (1150BC) who ruled Ireland with his brother Cermna Finn, he built a strategic fortress here to rule the north, the location is named after him - Dunsobairce (Fortress of Sobairce) now Dunseverick.

Many heroes of Irish legends such as Cuchulain, Queen Maeve and Turlough are associated with the north coast. A story given to me by the late Bertie McKay, a local historian and fisherman from Portbraddon, explores more of the Adventures of  Turlough. Another interesting fact for anyone who walks up to the castle and takes in the breathtaking view to Portmoon - if you do, then you can rest safe in the knowledge that you have walked in the footsteps of Patricius (Saint Patrick) as it is known he visited Dunseverick on several occasions for baptisms and on one of these occasions he baptized a local man called Olcan, who became Bishop of Armoy and later a Bishop of Ireland, Olcan died in 480AD. He may well have baptised Gobain here to.

A well exists on the headland and is named after St. Patrick, it is reputed to be be one of the key  'holy' wells of Ireland, though sadly, the christening stone and the seat that he used still lies somewhere on the ocean bed having been tumbled into the sea when the castle site was attacked and destroyed during the 1641 rebellion.
