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 62 are known as Turret 62A (grid reference NY438604) and Turret 62B (grid reference NY435601). None of the turrets between Milecastles 59 and 72 were sought or identified prior to 1961, and the exact locations of turrets 62A and 62B have not been found.[2]
