Blanerne Castle is referred to in a traditional Berwickshire song:
Bunkle, Billie and Blanerne
Three castles strong as airn
Built when Davy was a bairn;
They’ll a’ gang doon
Wi’ Scotland’s croon,
And ilke ane sall be a cairn.
Blanerne Castle was destroyed by the Earl of Hertford during the Rough Wooing in 1544, and is now a ruin.
It is marked on Moll’s mid-18th century map as Blaneirn, seemingly as an empty fenced plot.
