Milecastle 19

Milecastle 20 (Halton Shields) was one of the milecastles on Hadrian's Wall (grid reference NZ01886868). It is situated in the hamlet of Halton Shields, and was excavated in 1935. There is no visible trace of the milecastle above ground.

Milecastle 18 (East Wallhouses) was a milecastle of the Roman Hadrian's Wall. It is located to the west of the settlement of East Wallhouses in Northumberland and is visible as a platform in the ground. The milecastle is of a unique construction, having a gateway associated with builders of the Legio II Augusta and a layout typical of the Legio VI Victrix or Legio XX Valeria Victrix. Historians have suggested that it may have been begun by men of one legion and finished by those of another. One of Milecastle 18's associated turrets shows evidence of being used as a workshop, possibly for the repair of shoes.

Newton is a village and former civil parish, now the parish of Bywell, in Northumberland, England. It is situated close to the A69 road, 3 miles (5 km) north of Stocksfield and 13 miles (21 km) west of Newcastle upon Tyne. In 1951 the parish had a population of 78.

Newton, Newton Hall and Stelling were three separate civil parishes from 1866 to 1 April 1955, when they were merged into the existing Bywell civil parish.

Aydon is a village and former civil parish, now in the parish of Corbridge, in Northumberland, England. It is about 2 miles (3 km) northeast of Corbridge on the B6321 road. The village is about 18 miles (29 km) from Newcastle upon Tyne along the main A69 road. The A68 road is close by, leading to Jedburgh and Darlington. Aydon lies near the course of the ancient Roman monument, Hadrian's Wall. In 1951 the parish had a population of 90.

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 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.

Fenwick Tower was a 12th-century tower house at Fenwick, Matfen, Northumberland, England. The house was the home of the Fenwick family from the 12th century until they moved to Wallington in the 16th century.In 1378 John Fenwick was granted a licence to crenelate the house. The tower was largely demolished in about 1775 at which time a hoard of medieval gold coins was discovered.The sparse remains of the tower are now incorporated into a 17th-century farmhouse and are protected by Grade II listed building statusOn 15 February 2010 human remains were found buried next to a cottage in the hamlet of Fenwick Towers. Radio-carbon dating of the remains indicated they likely dated to the 13th or 14th centuries.

Hunnum (also known as Onnum, and with the modern name of Halton Chesters) was a Roman fort on Hadrian's Wall located north of the modern-day village of Halton, Northumberland in North East England. It was the fifth fort on Hadrian's Wall and is situated about 7.5 miles west of Vindobala fort, 5.9 miles east of Chesters fort and 2.5 miles north of the Stanegate fort of Coria (Corbridge). The site of the fort is bisected by the B6318 Military Road, which runs along the route of the wall at that point. The fort may also have guarded Dere Street which crosses the Roman Wall through the valley immediately to the west, but its distance from Dere Street and that Milecastle 22 was also displaced from Dere Street implies that this was not a priority and may have been expected to be disused north of the Wall after Hadrian's Wall was built.The Latinised Brittonic name “Onnum” may mean "Stream/Water", "Ash tree", or “Rock”; if it means "Stream", it may be a reference to the Fence Burn, where a stream touches the line of Hadrian's Wall, but if it means "Rock", it may refer to Down Hill situated to the east of it.
