Etal Castle, Etal Castle stands beside a ford across the peaceful River Till, near the Scottish border with Northumberland. In 1341 Robert Manners was granted a license to crenellate, and the result was the second quadrangular castle to be built in Northumberland. Manners built a sturdy tower house within a barmkin, or enclosure wall, with earthwork defenses running down to the river. The curtain wall was entered through a strong gatehouse and defended by a corner tower.
Greystoke Castle Castle rebuilt as a country house. On a medieval site incorporating parts of the building licensed to crenellate 1353, for the Greystock family. Damaged during the Civil War, partly rebuilt in late C17 and refronted 1710 for the Howard family, with mid C18 alterations for 10th Duke of Norfolk.
