Cornhill-on-Tweed is a small village and civil parish in Northumberland, England about 1 mile (1.6 km) to the east of Coldstream, Scotland.

[2] The earliest documented references to the village are in The History and Antiquities of the County of Durham[3] where a William de Cornale is mentioned in 1239.

In 1385 as part of the Hundred Years War, a Franco-Scottish force under the command of Jean de Vienne along with his allies the Earls of Douglas, March and Fife destroyed Wark and Cornhill Castles.

From 1543 the Cornhill garrison played an active part in the Rough Wooing cross border raids into Scotland.

[11] In 1557 the Tower, now surrounded by a defensive barmkin wall, was again attacked by a Franco-Scottish army, this time opposing the rule of Mary I.

[13] Cornhill House,[14] a Grade 2* listed building, is at the western end of the village, overlooking the River Tweed.

[15] Gilbert Swinhoe of Cornhill was the High Sheriff of Northumberland in 1642 at the outbreak of the English Civil War and raised the posse comitatus in support of the King.

After the war James was fined for his part in the conflict and it is likely that the Cornhill estate was sold to the Foster family in 1651 to pay the penalty.

[19] Cornhill-on-Tweed lies at a junction of the A697 and A698 roads - the latter linking to Berwick-upon-Tweed, the nearest significant town, some 13 miles (21 km) away.
