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 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 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 13 (Rudchester Burn) was a milecastle of the Roman Hadrian's Wall. Its remains exist as a low platform south of the B6318 Military Road.
Milecastle 14 (March Burn) was a milecastle of the Roman Hadrian's Wall. Its remains exist as a low (maximum 0.4 metres (1.3 ft) on the west side) platform, south of the B6318 Military Road and about 1 kilometre (0.62 mi) to the west of the road junction at Rudchester Farm.
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 17 (Welton/Whittledean) was a milecastle of the Roman Hadrian's Wall. The milecastle is located near to the Whittle Dene reservoirs and is visible as a platform in the ground. Just 174m west of the milecastle is a distinct change in wall construction, indicating that it may have formed a boundary between different legions. The existence of the milecastle has been known since at least 1732 and excavations have produced numerous finds and evidence of post-Roman occupation. The associated turrets both lie beneath the B3618 Military Road. A stone found near the milecastle is the only known written record of the name of Gaius Julius Marcus, a Roman Governor of Britain whose name has been erased from other inscriptions possibly because he fell out of favour with Emperor Caracalla.
Milecastle 19 (Matfen Piers) was a milecastle of the Roman Hadrian's Wall. Sited just to the east of the hamlet of Matfen Piers, the milecastle is today covered by the B6318 Military Road. The milecastle is notable for the discovery of an altar by Eric Birley in the 1930s. An inscription on the altar is one of the few dedications to a mother goddess found in Roman Britain, and was made by members of the First Cohort of Varduli from northern Spain. The presence of the Vardulians at this milecastle has led to debate amongst archaeologists over the origins of troops used to garrison the wall. A smaller altar was found at one of the two associated turrets.
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 26 (Planetrees) was a milecastle of the Roman Hadrian's Wall. Its position is slightly to the south of, but mostly covered by the B6318 Military Road., and it is located around 700 metres (0.43 mi) east of the B6318 Military Road's junction with the A6079. No visible traces exist currently. The dimensions are the same as Milecastles 23, 24, and 25.

Masonry from the east wall (both faces) remains in situ. The remaining stretch is 3.1 metres (10 ft) in length by 2.25 metres (7.4 ft) thick, and survives to a height of 0.6 metres (2.0 ft). It is located at the western part of Limestone Corner, just off the B6318 Military Road.

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.
Milecastle 33 (Shield on the Wall) was a milecastle of the Roman Hadrian's Wall, one of a series of small fortlets built at intervals of approximately one Roman mile along the length of the UNESCO World Heritage Site in northern England.
