Milecastle 6

Milecastle 48 (Poltross Burn), is a milecastle on Hadrian's Wall (grid reference NY6340666195). Its remains lie near the village of Gilsland in Cumbria where it was historically known as "The King's Stables", owing to the well-preserved interior walls. Unusually a substantial section of stone stairs has survived within the milecastle. The two turrets associated with this milecastle have also survived as above-ground masonry.

Milecastle 3 (Ouseburn) was a milecastle of the Roman Hadrian's Wall. No remains exist, but it was thought to have been located at the junction of the A187 Byker Bridge and Stephen Street.

Milecastle 1 (Stott's Pow) was a milecastle of the Roman Hadrian's Wall. It was located near the (now disappeared) valley of Stott's Pow. Its remains are covered over, and are located beneath the recreation ground at Miller's Dene. Early excavations and investigations of Turret 0B were mistakenly interpreted as Milecastle 1. The Milecastle sits within the parish of Wallsend.

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, in the parish of Wallsend.

Milecastle 5 (Quarry House) was the first milecastle west of Pons Aelius fort of the Roman Hadrian's Wall. No remains exist of the milecastle, though its supposed position is at the junction of the A186 Westgate road and the B1311 Corporation Street. No remains currently exist.

Milecastle 7 (Benwell Bank or Benwell Hill) was a milecastle of the Roman Hadrian's Wall. The milecastle itself has not been discovered by archaeologists and its presumed location lies beneath a modern housing development. Roman finds have been made in the area and the associated structure of Turret 7B is a significant surviving structure of the wall.

Milecastle 8 (West Denton) was a milecastle of the Roman Hadrian's Wall. Its remains are located in West Denton, Newcastle upon Tyne. The milecastle has two associated turret structures that are known as turret 8A and turret 8B. The turrets and milecastle were excavated in the 1920s, yielding some pottery and stone carvings, and have since been overlain by modern roads. The exact location of the structures is disputed, with the road hiding any surface traces. The Milecastle forms part of the Hadrian's Wall World Heritage Site.

Milecastle 9 (Chapel House) was a milecastle of the Roman Hadrian's Wall. Its remains exist partially as a low platform, and are located in West Denton (to the west of Newcastle upon Tyne), 300 yards (270 m) from Chapel House Farm. However, the northern part of the remains are now mostly covered by the modern roads (A69/B6528). The milecastle marks a watershed between those with relatively well-defined positions (to the west) and those whose position are less certain (to the east).

Milecastle 10 (Walbottle Dene) was a milecastle of the Roman Hadrian's Wall. It is located near to the modern village of Throckley in Tyne and Wear, northern England. Much of the milecastle lies beneath a road but partial remains of the north wall can be seen in the garden of Dene House. It has been excavated several times and its walls located, though the remains have been "considerably damaged by ploughing". Only one of the two associated turrets has been located and excavated.

Milecastle 12 (Heddon) was a milecastle of the Roman Hadrian's Wall. Its remains lay under Town Farm, Heddon-on-the-Wall, (just opposite the farm house) with nothing visible on the surface.

Milecastle 15 (Whitchester) was a milecastle of the Roman Hadrian's Wall. Its remains exist as a bold platform with robbed walls located on the southern side of the B6318 Military Road approximately 3 kilometres (1.9 mi) west of its crossing of the A69 road. It has not been excavated.

Milecastle 16 (Harlow Hill) was a milecastle of the Roman Hadrian's Wall. The milecastle is located at Harlow Hill, Northumberland. There are no visible surface remains of the milecastle or either of its associated turrets.

Milecastle 21 (Down Hill) was a milecastle of the Roman Hadrian's Wall. The site was identified by measurement only, as the milecastle's remains have been totally removed. This is probably due to extensive quarrying at the site, which now lies under pasture (and partly beneath the Military Road).

Milecastle 22 (Portgate) was a milecastle of the Roman Hadrian's Wall. Its remains exist as a low, turf covered platform just east of the Portgate roundabout (junction of the A68 and B6318). The platform is 0.5 metres (1.6 ft) on the east side, reducing to only a parch mark on the west side.

Milecastle 23 (Stanley) was a milecastle of the Roman Hadrian's Wall. Its remains exist as a low, grass covered platform with traces of an external ditch (as Milecastle 25). It is located to the south of the B6318 Military Road around 1.5 kilometres (0.93 mi) west of its junction with the A68.

Milecastle 24 (Wall Fell) was a milecastle of the Roman Hadrian's Wall. Its remains exist as a low platform, and are located to the south of the B6318 Military Road around 3 kilometres (1.9 mi) west of its junction with the A68.

Milecastle 25 (Codlawhill) was a milecastle of the Roman Hadrian's Wall. Its remains exist as a low platform, and are located to the south of the B6318 Military Road (about 1 metre (3.3 ft) high), nearly 5 kilometres (3.1 mi) to the west of its junction with the A68.

Milecastle 28 (Walwick) was a milecastle of the Roman Hadrian's Wall in England. No remains are currently visible. Its location is immediately to the south of the B6318 Military Road in Walwick.

Milecastle 31 (Carrawburgh) was a milecastle of the Roman Hadrian's Wall. Its remains exist as a turf covered platform beside (and partially covered by) the B6318 Military Road, just to the east of Carrawburgh fort (adjoining the car park).

Milecastle 32 (Carraw) was a milecastle of the Roman Hadrian's Wall. Its remains exist as earthworks and with no exposed masonry. The layout of the milecastle walls is defined (still quite evident) by robber trenches (to a maximum depth of 0.3 metres (1 ft 0 in). The north wall is beneath a modern wall.
