 The pillboxes at Hazon, Brainshaugh, Morwick, West Thirston, Earsdon, Longhirst, Bothal Barns and East Moor (and possibly Eshott) form a line with the pillboxes approximately two miles apart.There is a further modified lozenge pillbox in Rothbury.It is a standard "lozenge" except for an alteration to the porch and door, which were built on the left hand side as opposed to the rear.
