Milecastle 51 (Wall Bowers) was a milecastle on Hadrian's Wall ({{gbmapping|NY59306549}}).
Description
Milecastle 51 is west of Birdoswald fort ({{gbmapping|NY59306549}}), at the point where the Stone Wall rejoins the line of the Turf Wall.F. Gerald Simpson and I. A. Richmond, "The Turf Wall of Hadrian, 1895–1935," Journal of Roman Studies, 25 (1935), pp. 1–18. It lies 1501m west of Milecastle 50 and 1484m east of Milecastle 52. The remains are in poor condition, consisting of turf covered foundations with traces of a ditch to the east.[http://www.pastscape.org.uk/hob.aspx?hob_id=12630 MILECASTLE 51], Pastscape, retrieved 4 December 2013
Excavations
The milecastle was excavated in 1927, 1934 and 1936. Although not now visible, excavation showed that it had two internal stone barracks buildings. It had Type III gateways.
The stone milecastle replaced its underlying predecessor, Milecastle 51TW, on the Turf Wall.

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 51 are known as Turret 51A and Turret 51B.
=Turret 51A=
Turret 51A (Piper Sike) ({{gbmapping|NY58826530}}) is of the type normally associated with the Turf Wall, and later replaced in stone.[http://www.pastscape.org.uk/hob.aspx?hob_id=12627 PIPER SIKE TURRET], Pastscape, retrieved 4 December 2013 The turret was excavated in 1927 and again in 1970. The entrance was on the east side and a substantial platform against the north wall. Cooking hearths and rubbish were found spread over the rest of the turret. Occupation is not believed to have continued later than the 2nd century AD. The turret was consolidated after 1970 and survives to a maximum height of 0.8 metres.

{{Main|Leahill Turret, Hadrian's Wall}}
Turret 51B (Leahill) ({{gbmapping|NY58386511}}) measures 4.1 by 4.3 metres. It was excavated in 1927 and again in 1958.[http://www.pastscape.org.uk/hob.aspx?hob_id=12622 LEAHILL TURRET], Pastscape, retrieved 4 December 2013 It replaced the earlier Turf Wall turret. The stone turret has been consolidated and survives to a maximum height of 1.1 metres.
