Alwinton Parish is one of the largest parishes in the Cheviot Hills. The main settlements within the parish are: Alwinton, Barrowburn; Blindburn; Linbriggs; Makendon and Shilmoor.
It is almost entirely upland reaching from the Scottish Border at Chew Green in the west to Alwinton in the east, and from the Auchope Cairn on The Cheviot in the north to the edge of the River Rede in the south. Most land is given over to sheep-grazing, army training on the Otterburn Training Area, and coniferous forests. In places the parish boundary uses well-defined lines such as the Scottish Border, Clennell Street drove road and Dere Street.(Ref: Keys to the Past).
