What is recorded here

Craigbolie Castle, also called Dun Crutheni, is a large earthwork enclosure in Tamlaght, County Derry, scheduled for protection and recorded without a clear human date. The land may have held people long before written history, yet no exact name, event or date is known.

The official Northern Ireland record identifies this as LARGE EARTHWORK ENCLOSURE: Craigbolie Castle or Dun Crutheni. Recorded period: E.CHRIST.. Recorded protection: Scheduled. The official map point was placed at the centre of the recorded archaeological site from the source map reference.

Built by the Ó Cellaigh (O'Kelly) clan of the Cruthin, an early Irish people, around the 5th to 7th centuries AD. It is important as a rare example of a pre-Viking defensive earthwork in Ulster, reflecting early medieval settlement and territorial organization in the region.
