Milecastle 61

Each milecastle on Hadrian's Wall had two associated turret structures. These turrets were positioned approximately one-third and two-thirds of a Roman mile to the west of the Milecastle, and would probably have been manned by part of the milecastle's garrison. The turrets associated with Milecastle 61 are known as Turret 61A (grid reference NY451607) and Turret 61B (grid reference NY447606). None of the turrets between Milecastles 59 and 72 were sought or identified prior to 1961, and the exact locations of turrets 61A and 61B have not been found.^[1]
