Milecastle 2
Milecastle 2 was a short-axis milecastle of unknown gateway type. Short-axis milecastles were thought to have been constructed by the legio II Augusta who were based in Isca Augusta (Caerleon). Northing: 6482, Easting: 2705 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 2 are known as Turret 2A and Turret 2B. No remains have been identified of Turret 2A. Two locations have been suggested, one by Eric Birley in 1961,
based on Horsley's locations of Milecastle 2 and Milecastle 3,and an alternative by Grace Simpson in 1978, based on Maclauchlin's locations of Milecastle 2 and Milecastle 3.
