Milecastle 2 (Walker) was a milecastle of the Roman Hadrian's Wall. No remains are currently visible, having been built over, but its probable location is at or near the junction of the A187 Fossway and Tunstall Avenue.
Excavations and investigations
- 1848 - Collingwood Bruce studied the wall and found the site to have been covered by a brick kiln.
- 1852-4 - Henry MacLauchlan surveyed the milecastle's position, reporting it as short-axis, and recorded.
|“||faint traces of it being discernible in the ploughed ground.||”|
- 1928 - FG Simpson attempted to locate the site, but despite the previous removal of the brick kiln, found only Roman occupation earth and debris. He recorded distances from the presumed location to the centre of Milecastle 1 as 1,453 yards (1,329 m), and to the centre of Milecastle 3 as 1,453 yards (1,329 m).
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.
