This 1.8m (6ft) tall standing stone probably dates originally from the Bronze Age, but was re-used in the late Iron Age/Celtic period (5th or 6th century AD) when an inscription was carved along the northern face of the stone. This read RIALOBRANI CVNOVALI FILI, (the FILI is now below ground) which is a Latinised form of Cornish, and means ‘Royal Raven, son of the famous leader’. It was thus a memorial stone to the son of a tribal leader of an Iron Age clan or tribe, whose name was taken from Bran, a mythic Celtic God or Chieftan written about in the early Welsh saga The Mabinogi. The story of Rialvran is also recorded in fragmentary form, and tells of how a great battle was fought at this spot, as Rialvran tried to recover his father’s lands from an interloper who had seized them. Rialvran was defeated but this memorial was erected to him here. The stone collapsed in the 19th century when someone dug under it hoping to find treasure, but was subsequently replaced in the same spot.
