The domain of the Cenél nGabráin appears to have been centred in Kintyre and Knapdale and may have included Arran, Jura and Gigha. The title king of Kintyre is used of a number of presumed kings of the Cenél nGabráin. Two probable royal sites are known, Dunadd, which lies at the northern edge of their presumed lands, and Aberte (or Dún Aberte), which is very likely the later Dunaverty on the headland beside Southend, Kintyre.
