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 was a milecastle of the Roman Hadrian's Wall. It was located near the 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 5 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 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 11 was a milecastle of the Roman Hadrian's Wall. No remains exist, but the measured position is the middle of the old village of Throckley Bank Top, under the Working Men's Club.
Milecastle 21 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.
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. 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 27 was a milecastle of the Roman Hadrian's Wall. It was located on the line of Hadrian's Wall, approximately midway between the A6079 and the River North Tyne. Its remains survive as a slight squarish platform with a maximum height of 0.4 metres (1.3 ft), but it is poorly defined to the north and east.
Milefortlet 21 was a Milefortlet of the Roman Cumbrian Coast defences. These defences were contemporary with defensive structures on Hadrian's Wall. Its remains exist as reconstructed turf ramparts and ditch, reinstated to its original profile. They are located on a low cliff on the coast, north of the village of Crosscanonby, and just inland from the coastal road. It is the only milefortlet to have been fully excavated and is open to the public.
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 34 (Grindon) was a milecastle of the Roman Hadrian's Wall. There are no visible remains, but the site is within a small, tree-filled, walled enclosure located around 0.5 kilometres (0.31 mi) east of Sewingshields farm.
Milefortlet 9 (Skinburness) was a Milefortlet of the Roman Cumbrian Coast defences. These milefortlets and intervening stone watchtowers extended from the western end of Hadrian's Wall, along the Cumbrian coast and were linked by a wooden palisade. They were contemporary with defensive structures on Hadrian's Wall. There is little to see on the ground but Milefortlet 9 has been located on aerial photographs.
Milefortlet 16 was a Milefortlet of the Roman Cumbrian Coast defences. These milefortlets and intervening stone watchtowers extended from the western end of Hadrian's Wall, along the Cumbrian coast and were linked by a wooden palisade. They were contemporary with defensive structures on Hadrian's Wall. There is little to see on the ground but Milefortlet 16 has been located.
Milefortlet 17 was a Milefortlet of the Roman Cumbrian Coast defences. These milefortlets and intervening stone watchtowers extended from the western end of Hadrian's Wall, along the Cumbrian coast and were linked by a wooden palisade. They were contemporary with defensive structures on Hadrian's Wall. There is little to see except a slight depression in the ground, but Milefortlet 17 has been located and surveyed.
Milefortlet 20 was a Milefortlet of the Roman Cumbrian Coast defences. These milefortlets and intervening stone watchtowers extended from the western end of Hadrian's Wall, along the Cumbrian coast and were linked by a wooden palisade. They were contemporary with defensive structures on Hadrian's Wall. There is little to see on the ground, but Milefortlet 20 has been located and excavated.
Milefortlet 13 was a Milefortlet of the Roman Cumbrian Coast defences. These milefortlets and intervening stone watchtowers extended from the western end of Hadrian's Wall, along the Cumbrian coast and were linked by a wooden palisade. They were contemporary with defensive structures on Hadrian's Wall. The exact location of Milefortlet 13 is unknown, although two of the nearby turrets have been located and excavated.
Milefortlet 15 was a Milefortlet of the Roman Cumbrian Coast defences. These milefortlets and intervening stone watchtowers extended from the western end of Hadrian's Wall, along the Cumbrian coast and were linked by a wooden palisade. They were contemporary with defensive structures on Hadrian's Wall. The site of Milefortlet 15 has been probably been destroyed by coastal erosion. A 3rd-century Roman cemetery, associated with a nearby fort at Beckfoot, was located in the area of the milefortlet.
Milefortlet 11 was a Milefortlet of the Roman Cumbrian Coast defences. These milefortlets and intervening stone watchtowers extended from the western end of Hadrian's Wall, along the Cumbrian coast and were linked by a wooden palisade. They were contemporary with defensive structures on Hadrian's Wall. Milefortlet 11 has never been accurately located on the ground although other Roman remains have been found in the area.
Milecastle 67 (Stainton) is a conjectured milecastle of the Roman Hadrian's Wall. The site of the milecastle has been calculated from measurement to known milecastle sites, but no remains providing proof of its existence have been identified, though Roman coins were found in 1861, during the digging of the adjacent railway cutting.
Milecastle 68 is a conjectured milecastle of the Roman Hadrian's Wall. The site of the milecastle has been calculated from measurement to known milecastle sites, but no remains providing proof of its existence have been identified.
