Ralph Clegham is listed as the farmer at Tunstall Hill in Whelan's 1856 Directory of County Durham.

An enclosed settlement probably of Iron Age origin consisting of a ditched enclosure associated with a number of roundhouses was recorded during an evaluation by TWM in 2012 along with a prehistoric pit alignment (HER16300). Roman pottery recovered from the site does suggest that the settlement may have continued in occupation into the Roman period. Only two sides of the inner enclosure were established during the evaluation - the northern and eastern sides. An approximate internal width of c.47m has been calculated for the inner enclosure. Three roundhouses were identified within the enclosure representing different phases of occupation. The central roundhouse had a diameter between 8-12m. There were also the remains of other postholes, drainage gullies and ditches within the inner enclosure which has clearly been the focus of intensive occupation. A possible outlying roundhouse was recorded to the west of the settlement supporting the possibility that other clusters or single roundhouses may exist in the area of the outer enclosure. Iron Age and Roman pottery were recovered from the site. Several examples of narrow gullies in close proximity to the inner enclosure ditches may represent palisade trenches. It is unclear how this potential palisade relates to the rest of the settlement.
In 2015 and 2017 an archaeological strip, map and sample was conducted by Wardell Armstrong in advance of residential development (event 4936). In area 1 curvilinear enclosures, pits, gullies, ditches, postholes and ridge and furrow were identified. Circular gullies with diameters that measured between 17.5 and 12m that maybe roundhouse ring gullies were also identified. Mid to late Iron Age pottery was found in association with features in area 1 in addition to bee-hive and saddle quern stone found in the upper fills of some features. A glass bangle fragment was also recovered. In area 2 a cobble spread was encountered which may be the remains of a cobbled trackway, ridge and furrow and linear features. No charred remains suitable for radiocarbon dating were recovered. The report recommends that future archaeological works conducted on the site should focus on retrieving dating evidence.
Post excavation analysis of the site was carried out in 2020 (event 5131). This found that the site was occupied between 350 cal BC and 345 cal AD, with several other undated phases of occupation. The settlement of roundhouses was initially unenclosed, and over time the roundhouses were replaced and enclosed with intermittent boundary ditches and then a large enclosure ditch with a complex entrance. The settlement was located in a manmade environment of lowland heathland with open moorland which supplied fuel in the form of both turf and coal. The finds assemblage was predominantly Iron Age in date and included pottery and some Roman artefacts.

A pit alignment consisting of individual pits and linear features was recorded during an evaluation by TWM in 2012 running in an east south-easterly direction. A ditched enclosure was also recorded (HER 16301). Similar pit alignments have been excavated at Delhi, Fox Covert and Shotton and dated to late Bronze Age. These pit alignments probably functioned at least in part in a role demarcating the landscape perhaps defining territories. Where dated, there is evidence that these features were open of r along period of time throughout the Iron Age. The pits on this site were relatively well preserved. A very small fragment of flint was recovered from one ditch sample. Trench 35 revealed two cuts - the earliest representing a large pit or ditch measuring 1.7m x 0.81m in depth with steep sides and a narrow base. Trench 38 revealed four pits and several linear cuts. The pits were orientated ESE and spaced between 0.53-0.6m apart. Only the full length of the middle two pits was exposed measuring 3.05m and 3.14m.

Dame Dorothy Street, Providence Chapel (Methodist New Connexion) dating from 1854. Listed as mission room on the Third Edition map of 1919.

Vicarage shown on Second Edition Ordnance Survey, 1897. Demolished between 1941-1973, replaced by Royal Naval Club (HER16299).

Bethesda Hallgarth Mission (Primitive Methodist) Chapel shown on Bright Street on the First Edition Ordnance Survey plan, 1855. Still labelled as church 1973. Origins in ‘revivalist enthusiasm’ at activities of Hettie Gutcher, the 'girl-singing-preacher – became the ‘Gutcher-Johnson Memorial Church’. Rebuilt 1928, destroyed in World War II, reopened 1951.

Speedings Ltd (previously J. Speeding and Co.) is Sunderland's oldest manufacturing business, established in 1827. In 2004 Speedings moved to Leechmere Industrial Estate from Whickham Street. Speeding Sail manufactory on Whickham Street shown on the Second Edition ordnance survey plan 1897. The larger building on the north side of the street is first shown on the Third Edition plan 1919. The building on Whickham Street was recorded in 2015 ahead of demolition. It is a two storey brick structure the central element of which seems to represent a purpose built sail-loft with an attached house. The domestic building had been built by 1914, this was later altered to become part of the sail works. In its entirety, Speedings' Buildings represents part of a vitally important industry to the history of Sunderland and a part of the wider shipbuilding heritage of the city.
