What is recorded here

Sie Fionn still stands in Ballyknock, County Derry, a prehistoric marker older than written memory. The stone may have guided herds, marked a boundary or watched a funeral fire, yet its exact purpose has faded like the hands that placed it.

The official Northern Ireland record identifies this as STANDING STONE: SEFIN or SIE FIONN. Recorded period: UNCERTAIN; PREHISTORIC. The official map point was placed at the centre of the recorded archaeological site from the source map reference.

Likely dating to the Neolithic or Bronze Age, this standing stone may have had ritual or territorial significance. The name "Siefionn" could reflect later folklore, possibly linked to the Fianna or local hero legends.

The monument record does not grant public access. Check the route and ask the landowner before entering private land.
