Highfield Cottage Homes erected in the early 1900s - first shown on the 1919 Third Edition Ordnance Survey Plan. The cottages provided children's accommodation away from the main workhouse. Each cottage was supervised by a house 'father' or 'mother'.

Early 20th century hospital and landscaped gardens facing Kayll Road, first shown on the 1919 Third Edition Ordnance Survey plan. Part of the expansion of the 19th century hospital and workhouse.Under the National Health Service, the hospital became Sunderland General Hospital.

Archaeological excavation south of East Wideopen Farm between October 2015 and February 2016 revealed evidence of an Iron Age/Romano-British field system, a probable enclosure, at least ten roundhouses of different phases, postholes and pits.

The field system took the form of two rectangular fields with possible internal divisions. The fields were separated by an east-west trackway or droveway. The field boundary ditches were up to 2m wide and 1m deep and were u-shpaed in profile. In the northern end of one of the ditches Samian pottery, Roman glass and a quernstone was found. The field system is possibly a 'ladder' field system (a series of fields or paddocks, rectangular in shape and often fronting onto a trackway.

In the north-west part of the site, a sizeable ditch 2.3m wide and 0.98m deep formed the southern and eastern arm of a potential rectilinear enclosure.

The remains take the form of an area of dense occupation, possibly representing an earlier unenclosed settlement, followed by an enclosed settlement and field system. The field system is similar to those at Pegswood, Gardener's Houses and Faverdale. One roundhouse has been dated by pottery to the 1st century AD. The average diameters of the roundhouses are between 4m and 8m. Industrial slag has been identified which is the product of pre-indistrial iron smelting, possibly from a bloomery furnace.

Finds included 242 pottery sherds including a possible wheel-thrown pot and a probable C1 bowl (rare in the NE Iron Age), several quernstones, a possible mortar or stoup and several pot boilers.

Soil samples contained molluscs (oyster and umbo), charred plant seeds, oak, willow, cherry and heather charcoal. Animal bone was equid, cattle, sheep or goat.

The site of East Wideopen Farm was archaeologically excavated in 2017. Another enclosed Iron Age/Romano-British settlement and field system were recorded. There was a sequence of roundhouses (average size 7m), pits, postholes, two possible cremation burials and a sub-rectangular enclosure. The majority of the roundhouses seem to have been built prior to the enclosure and represent an unenclosed settlement. Only ring-gully 3179 seems to post-date the enclosure.

The enclosure measured approx 46m x 40m in plan and was divided internally by ditches. The main enclosure ditch was mostly u-shaped in profile and was 3.32m wide and 0.84m deep.

Two ditches within the field system may have formed a trackway or droveway. Alternatively they have formed part of a 'ladder' field system like that found at East Wideopen in 2016 (excavation by NAA), the ditch being an internal partition possibly forming a paddock. The ditches within the field system were around 1.59m wide and 0.57m deep, but they had been truncated by the later farm buildings. They were mostly v-shaped in profile, some sections were u-shaped.

Post-medieval furrows were recorded running east-west and various post-medieval ditches, culverts and farm building foundations including the site of the gin-gang. There were two animal burials (one was a mixture of equid, cattle, pig, cattle or red deer, another burial was pig and sheep or goat and the third was the hind limbs of a cow), a sandstone well and two barrel bases, probably buried as refuse receptacles.

Artefacts included five prehistoric pottery sherds, including two rims with fingernail impressions, a beehive quernstone, 1 lithic, 17th to 19th century pottery (largely found in the barrels).

Palaeo-environmental assessment produced cereal grains (spelt, emmer, barley and wheat), oak charcoal, gypsywort which suggests a wetland character to the site, curly dock or heathgrass (thatch materials) and rushes (bedding).

Animal bone - cattle, sheep or goat, pig and equid, mostly of post-medieval date.

Coal depot shown on the First Edition Ordnance Survey Plan 1857. Possibly gone by the 1890s. The coal depot was archaeologically excavated in 2016. It took the form of brick floors on the south-east side of a railway embankment (HER 3620) arranged around a large stone structure, composed of squared shaped sandstone blocks. The coal depot was subdivided by a central dividing wall. There was a square brick pier at the eastern end. The depot was open to the west and the eastern side was cut into the railway embankment. The heavily-decayed remains of a timber superstructure were found in both bays. A substantial brick culvert ran in front of the depot. After it went out of use, the coal depot was covered by thick deposits of silty coal waste from surrounding spoil heaps. A thick deposit of clay sealed the site as part of a 20th century ground remediation measure.

Corving Row (a corf or corve is a wicker basket or minecart used for carrying coal), a row of terraced housing shown on the First Edition Ordnance Survey Plan 1857. The houses, associated with Rainton Colliery, were built around the 1840s and were demolished by the later 1930s. One of the brick-built houses was archaeologically excavated in 2016. It had two ground floor rooms, equipped with a fireplace and range. To the rear were a series of yards, walls, outbuildings and privies.

Field House Farm (c.1890) consists of two two-storeyed ranges - the Main Range and the North Range forming an inverted T plan. A single-storeyed South East and South West Range adjoined either end of the longer Main Range and returned to the south. The South East Range has been demolished but the short South Range remains in ruinous condition. The buildings are constructed of roughly-coursed yellow Magnesian Limestone rubble, with raised quoins and dressings expressed in olive brick (original) or orange brick (secondary phase). The original roofs where they survive are of Welsh slates, but have partly been replaced by corrugated sheeting. Farm buildings are of local interest, notably in demonstrating late 19th-early 20th century building techniques in which variously-coloured brickwork were used as an economical alternative to cut stone quoins and dressings. Changing agricultural needs of the later 20th century needs for larger spaces to house machinery and vehicles have meant that floors have been removed and walls demolished, so that little more than the shells of parts of the original buildings survive today.

Farm shown on First Edition Ordnance Survey plan, 1857. By the late 19th century Hendon Paper Works formed the southern boundary of the farm. The farm was demolished fully by 1919.

The foundation stone for Cherry Knowle Hospital (Borough Lunatic Asylum) was laid by Alderman Stansfield Richardson in 1893 and the main building (The Laurels) was completed in 1895. The architect was George Hine and he designed a compact arrow-shaped layout consisting of six blocks of wards with a recreation hall and chapel in the south elevations.The hospital also comprised of The Oaks an isolation ward to the north-west of the main building, The Elms (1902) a consulting doctors office and later an isolation ward to the north-west and The Cedars to the south of the main building. Associated buildings included a nurses' home to the west, morgue, terraced cottages for married staff, a lodge cottage and the Superintendent's house. Field House to the south-west of the main building was also used as an isolation ward and later as office accomodation and reception for the site. The buildings were all of red brick with stone dressings and slate roofs with distinctive caps over the bay windows (a hallmark of Hine's early work). The 1919 OS plan shows the hospital had been expanded. It continued to expand throughout the 20th century and was known as Cherry Knowle from the late 1940s. The hospital closed in 1998 and was demolished in 2011. The buildings were recorded ahead of demolition.

Evidence for early coal mining was identifed during excavations at Sunnybank Avenue, Benwell. Two possible bell pits (HER 16262) and extensive drift mining galleries were revealed dating to the medieval and/or early post-medieval period. The galleries had been excavated in a north-west/south-east grid pattern following the pillar and stall method of extraction. This is an early form of mining which exploited rich coal seams closer to the surface before the introduction of deep coal mining in the late 16th century. The workings were an interconnected network of galleries extracting coal from a seam up to 2m thick. The galleries varied in width from 1-1.7m. Some of the galleries terminated abruptly, despite the presence of further coal deposits beyond which may indicate the presence of an estate boundary. There was no evidence of pit props, shoring or flooring.
