An older Otterburn Hall existed at least as early as 1777. At that time, the Hugh Percy, 2nd Duke of Northumberland asked the hall's owner, Henry Ellison, for permission to erect a monument on the field to honor his ancestor who died during the Battle of Otterburn. Ellison denied the request and raised a monument himself which included an obelisk, possibly an architrave removed from Otterburn Hall's kitchen fireplace, which was placed into a socketed battle stone.
