This sub-square feature was identified by a member of the public via LiDAR and aerial photography. It consists of a rough square of flattened ground measuring approximately 35m by 35m, within a field of medieval ridge and furrow (HER 11499) lying between Walbottle and Blucher. It is aligned northeast-southwest, in line with the ridge and furrow, and its western and eastern boundaries correspond with furrows whilst the northern and southern boundaries cut across them.
The feature clearly cuts and respects the ridge and furrow and therefore must post-date it, but its function is unclear. It may be a sports pitch for a game such as knurr and spell, where the ground is marked out with wooden markers every 20 yards, or associated with Walbottle Hall (HER 5028). It has not been identified on any historic Ordnance Survey mapping.

This tunnel is shown on the 1st edition Ordnance Survey map of 1862. It carried a farm track from Newton Garths Farm to the northeast (HER5482) under the embankment of the NER Newton Garths Branch (HER 2313).

A plot of 19th century shops and houses located south of Keel Square, Sunderland. The buildings are shown on the 1858 1st edition Ordnance Survey mapping. The buildings are shown to have been associated with yards and outbuildings such as stables, coal sheds and toilets. A smithy and warehouse are noted in the south west corner. Elements of the 19th century buildings are noted to have survived successive remodelling. The buildings were recorded in advance of demolition.

A large stone measuring 0.72m x 0.50m with a possible wheel rut worn into it was noted by a member of the public built into a field boundary wall, in the second course above ground level. Another large stone sits above it, and there are many other examples of outsize stones built into the wall at various points along its whole length. The stone with the possible wheel rut is postulated to have been reused from Milecastle 9 (Chapel House) (HER214); another potential source of stone for the wall would have been Turret 9a (HER215).
The wall bounds the field on the southern side of Hawthorn Terrace to the east of the village.

A brick lined well with stone blocks at the top was found inside 237 Westgate Road at the rear of the building during construction works. It is not shown on historic maps, and from Oliver's map of 1838 may have been located originally in the rear garden of a house on Greenfield Place, before the Westgate Road properties were built.

A series of sandstone walls identified during archaeological monitoring which was undertaken during groundworks prior to piling works at High Street West, Keel Square, Sunderland. The walls comprised of sandstone blocks with a mixture of finishes ranging from unworked, roughly-hewn and squared with tool marks. The stones were laid in regular courses and bonded with a crumbly grey mortar. The walls are likely to pre-date the late brick cellars which were recorded at the site. A series of palaeoenvironmental samples were obtained during the works in which frequent clinker/cinder, coal and coal shale, and trace quantities of charcoal were identified it is suggested that these deposits probably relate to the later medieval/post-medieval period. During the monitoring, fourteen sherds of pottery were obtained, the earliest comprised of a small-abraded body sherd of medieval reduced greenware of late 13th- to 15th-century date in addition to 18th- and 19th- century pottery, 19th- to early 20th- century glass and fragments of tobacco pipes and a damaged modern metal spool containing part of a reel of 16mm film. Faunal remains included the remains of limpet shell, sheep rib shaft fragment, mussel shell and winkle shell in addition to small unidentifiable fragments.

These two air raid shelters were found during site preparation for a new development at Gateshead Quays. They were constructed from brick, concrete and corrugated metal sheets, and may have been associated with the Machine Tool Works to the south west on Hawks Road, shown on Ordnance Survey maps of the 1940s-1950s.

The Leam is shown on the 1848 Tithe Plan of Hedworth and on the first edition Ordnance Survey map as a collection of buildings grouped around the end of a track coming from the northeast, to the southeast of the Bowes Railway (HER1005) and the Wrekendyke (HER277). The principal barns and gingang lie to the west, whilst the house and garden are to the southeast. By the time of the second edition Ordnance Survey map, four ranges of barns with a gingang at the western corner have bene built forming a courtyard to the north, whilst the former barns appear to have been replaced by a new range. This and the farmhouse appear to survive today.

The Monkwearmouth Hospital was constructed at the site off Newcastle Road between 1930 and 1932. A series of architectural plans from the 1920s for the new Monkwearmouth Hospital were produced by W & T R Milburn, Architects, Sunderland show the proposed drainage plan for the Monkwearmouth and Southwick Hospital. The original Monkwearmouth Hospital (Monkwearmouth and Southwick Dispensary) was constructed c.1870 and was located at the Workmen’s Hall situated on Whitburn Street. The new Monkwearmouth Hospital is typical of early 20th century municipal architecture. It is constructed from red brick, stone banding, cills and lintels and it has a slate roof. The hospital was constructed with large Georgian style sash windows on the ground and first floor and had smaller windows elsewhere. The entrance was designed with a central portico. The building was opened on the 27 July 1932 by Priestman. Edward VIII, the Prince of Wales, aided the construction of the hospital by calling for more community facilities and improvements in Sunderland. There are two commemorative stones at the front of the hospital, the first commemorates Sir John Priestman and the opening of the hospital, and the second is a foundation stone which was laid in 1930 by Edward VIII. Historic maps show the hospitals expansion to the southern part of the site between 1950-1990. Adjacent to the boundary wall, along Newcastle Road, a memorial crest of Joseph Lowes Thompson was recently identified Joseph Lowes Thompson was the shipbuilder who previously inherited the land and built Ashville House. The building has been heavily modernised over the years and rooms converted into modern offices and stores.

The Greenside War Memorial was listed Grade II in 2016 with the following description:
History
Greenside War Memorial was unveiled on 1 October 1921 by Lt-Col FR Simpson. It commemorates 57 local servicemen who died in the First World War. The memorial was funded by public subscription and designed and built by D Morrison of Gateshead. Following the Second World War the names of 26 men and one woman who died in that conflict were added. The name of a soldier who died of wounds received in Afghanistan was added in 2015.
D Morrison of the Art Memorial Works, Gateshead, was also responsible for the elaborate Celtic cross war memorial at Eighton Banks.
Details
The memorial stands at the north-east corner of a small memorial garden between Lead Road and Spen Lane. Approximately 6m tall, the Greenlaw stone memorial takes the form of a Classical obelisk. The slender obelisk, square on plan, is ornamented with a small swag and PRO/ PATRIA carved in low relief to the front face. The obelisk’s foot is decorated with laurels on each side, carved in low relief.
The obelisk rises from a tall corniced pedestal, that stands on a three stage base. The commemorated First World War names are listed on the four faces of the pedestal. The top stage of the base is inscribed with the principal dedicatory inscriptions:
(north-east face) SEE TO IT THAT THESE SHALL/ NOT HAVE DIED IN VAIN/ THEIR NAME LIVETH FOR EVERMORE
(north-west face) IN THANKFUL RECOGNITION OF/ THE MEN WHO GAVE THEIR SERVICES,/ AND IN GRATEFUL MEMORY OF THOSE WHO/ GAVE THEIR LIVES IN THE GREAT WAR.
(south-east face) ERECTED/ BY THE INHABITANTS OF/ GREENSIDE
(south-west face) FOR RIGHT, FREEDOM/ AND FOR PEACE
The commemorated Second World War names are recorded on the front faces of the middle stage of the base. On the top of the middle stage, to the front, is incised 1939 – 1945, whilst on the front face of the bottom stage is 1914 – 1918, carved in low relief. A small rectangular bronze plaque fixed to the north-west face of the bottom stage repeats one group of First World War names. The memorial is enclosed by a low stone kerb ornamented with eight plain stone cubes.
