Cessford Castle is a large ruined mid-15th century L-plan castle near the village of Cessford, midway Jedburgh and Kelso, in the historic county of Roxburghshire, now a division of the Scottish Borders. The Castle is caput of the Barony of Cessford, and the principal stronghold of the Kers/Kerrs, notorious Border Reivers, many of whom served as Wardens of the Middle March.
