Blanerne Castle is the remains of a 16th-century fortified house, located in the grounds of Blanerne House, an 18th-century country house between Chirnside and Preston in the Scottish Borders. The house and castle sit on the north bank of the Whiteadder Water, around 6 kilometres (3.7 mi) north-east of Duns.
The castle was the historical seat of the Lumsdaine family for over four centuries. The surviving remains are dated to the 16th century, although the site may have been occupied as far back as the 12th century. The remains include a keep or kitchen block, with a detached guard house to the west.[1] The castle is protected as a Scheduled Ancient Monument.[2]
A popular Berwickshire rhyme refers to the medieval strengths of Blanerne and the nearby fortresses of Billie Castle, and Bonkyll Castle referring to their construction in the time of David I and their destruction following the Rough wooing:
Bunkle, Billie and Blanerne
Three castles strong as airn
Built when Davie was a Bairn
Theyll all gang doon,
Wi Scotland's Croon
An ilka ane shall be a cairn
