An aerial photograph of 1959 shows what appears to be the faint outline of a hut circle. Given the date of the photograph, however, it is likely that the site has since been destroyed by ploughing.

On an aerial photograph is what appears to be a sub-oval enclosure containing circular features reminiscent of hut circles. A Bronze Age or Iron Age date is likely if the feature is indeed of archaeological origin. Not found during evaluation trenching in 2016 ahead of development of area.

Buildings at the junction of Drove Road and the Military Road were known as 'Lead House' by 1858, when they appear on the first edition Ordnance Survey plan, and were apparently store houses for the Langley Lead Company. The crossroads is captioned 'Lead gate' on the county maps of Greenwood and Fryer in the 1820s.

Two valve houses, built for the Newcastle and Gateshead Water Company in c.1870 and c.1890, stand on either side of Hexham Road as part of the improvements in the water supply to the growing town in the 1870s. LISTED GRADE 2

A wagonway is shown on a plan of Throckley, 1769 linking New Engine (HER ref. 1959) to another wagonway (HER ref. 1958). It is also shown on a plan of 1781 but not shown on the First edition Ordnance Survey plan of 1858, so was presumably out of use by that date.

An unnamed coal shaft is shown on an estate map of 1781, joined by a wagonway (HER ref. 1958) to Hill Pit (HER ref. 3952) and Meadow Pit (HER ref. 3953). Nmaed Queen Pit on ZAN/M17/197/a/24. It is not shown on the first edition Ordnance Survey plan of 1858, so was presumably out of use by that date.

First noticed on aerial photographs of 1977 (NMR MAZ/77024 Frame 049). An evaluation in 2003 (TWM Archaeology) recovered Iron Age pottery and structures. Excavated in 2004. The site actually comprised two rectilinear enclosures, one 20m north of the other. Only the southern one showed up clearly on aerial photographs. In 2008-9 a strip and record excavation on the line of a new spine road, revealed the west side of the northern enclosure. Phase 1/2 - unenclosed settlement. This phase contained over 40 circular or part-circular structures. Most house plots showed evidence of rebuild. The houses were built with continuous slots 300-400mm wide in which to set uprights. Some of the circular structures were very small (structure 25 was 5m in diameter). Plough damage had removed internal features. A calcinated sheep bone from the fill of the south terminal of the gully of rounhouse 4 was radiocarbon dated to 750-390 cal BC. Charred barley grains from the southern terminal area of rounhouse 6A was radiocarbon dated to 410-210 cal BC and 350 cal BC - cal AD 10. House 1A was larger than any other structure. It was architecturally more elaborate than any other. The outer wall slot contained an inner ring of posts set 2-2.75m inside the outer wall, defining a central area some 6.5m in diameter. The house was set within a rectangular palisade enclosing an area 33m x 27m. This must be a precursor to the phase 3 central house and large enclosure. Radiocarbon dates from house 1A were 410-260 cal BC, 360-160 cal BC, 385-200 cal BC. An internal ash pit or hearth was dated to 360-160 cal BC and 385-200 cal BC. An internal ash and charcoal filled scoop was dated to 770-380 cal BC. Roundhouse 35a was contained within a small sub-rectangular enclosure 11m x 8m internally. The enclosure ditch was 1.15m wide and 0.65m deep. The house faced east while the enclosure was open to the south so they may not have been contemporary. Two lengths of gully 0.9m wide and 0.55m deep cut houses 11 and 22, forming a two-sided rectinilinear enclosure. An unphased inhumation was found towards the eastern edge of the excavated area. Phase 3 - enclosed settlement. There were two principal rectilinear enclosures, 20m apart. Enclosure A was 43m x 34m. The ditch was between 5m and 8m wide. The undug causewayed entrance on the east side of enclosure A was 5m wide. Radiocarbon dates were 180 cal BC - cal AD 10 (primary silting of northern ditch), cal AD 60 - AD 240 and cal AD 50 - AD 220 (lowest waterlogged silting of north ditch terminal). Enclosure A contained a large east-facing roundhouse just west of centre. Its drainage gully was 0.70m to 1.5m wide. Radiocarbon dates were cal 50 BC - AD 130, 200-45 cal BC, 50 cal BC - cal AD 130. There was probably another smaller house towards the south-east corner. Enclosure B to the north was only partly excavated but measured 45m x 56-62m. The north side was a wide shallow ditch 4.5m wide and 1.2m deep. There were traces of burnt daub on its inner face. The infill was recut by a smaller V-shaped ditch 2.2m wide and 0.85m deep. The south side ditch had also been recut. The orginal ditch was V-shaped and steep-sided 4.5m wide and 1.60m deep. The recut was 4.5m wide and 1m deep. The western side was not parallel with the eastern . The east facing entrance was north of its centre. The entrance of the enclosure aligned with the entrance to the central roundhouse which contained a cup-marked stone in its south terminal. The large drip gully of the house had two phases. The house was 11m in diameter. A flat bottomed gully swung in an arc from the north side of the entrance forming a hornlike projection as observed in House H at East Brunton. Postholes were found inside the entrance, Two of them were door posts. The others may have supported an upper floor. The house may have been destroyed by fire at the end of its life. Radiocarbon dates were 50 cal BC - cal AD 70, 90 cal BC - cal AD 60. 22m south of enclosure A there was a shallow ditch running east-west. This was a wide shallow ditch 5m wide and 1m deep. It had been recut on at least two occasions. Radiocarbon dates were 50 cal BC - cal AD 70 and 40 cal BC - cal AD 130, cal AD 60-AD 230 and 40 cal BC - cal AD 210. A series of smaller ditches subdivided the space between the two major enclosures into discrete parcels. Another ditch was found 150m east of the south-east corner of the northern enclosure running WNW-ESE. This curved gently to the south-east and was up to 1.8m deep. It may have formed the eastern side of an outwork or outer enclosure. It therefore seems likely that the principal enclosures and the unenclosed phase 3 structures were all surrounded by a large outer enclosure or boundary ditch perhaps 300m east-west and up to 150m north-south. Finds from the excavation included 181 sherds of Iron Age pottery, some objects of fired clay, an iron pin 105mm long and 6mm deep, a sharpening stone, a small roughly circular sandstone disc (like that found at Murton High Crags in 1987 by Jobey), a stone pounder, a possible quern with cup-marking, a portable cup-marked stone, 2 saddle querns, 4 beehive uppers, 1 possible saddle quern, saddle top stone, 3 possible stone rubbers, possible quern fragment, 20 struck flints. Undiagnostic or possible smithing slag was recovered. Animal bone was cattle, sheep/goat, pig, horse. Biological remains included a single hazlenut shell fragment, glume wheat, barley, spelt wheat and sedges. Pollen analysis was carried out.

A map of circa 1730 lists field names East Liggers and The Liggers, and a plan of 1736 shows a large open area called "The Ligger" which was bounded by the line of Hadrian's Wall to the south, and by the boundary with Throckley Fell to the north. A mid-18th century plan of Throckley shows two large fields called East and West Leagure, and on a later plan of 1769 these had each been divided into two fields called North-East Ligger, South-East Ligger, North-West Ligger and South-West Ligger. A map of 1781 shows that North-East and South-East Liggers had been further divided into two fields each. This fieldname evidence suggests that part of the area may have been briefly occupied by the Scottish army under General Leslie before the Battle of Newburn Ford in 1640 (see HER ref. 1297). This corresponds with contemporary accounts, and it is possible that the name "The Ligger" and "Leagure" is a corrupted reference to this being part of the site of the Scottish army's encampment or leaguer, before Newburn.

A pumping shaft called 'the New Engine' is shown on a plan of 1769. It was served by a wagonway (HER ref. 1963) which was in turn linked to another wagonway (HER ref. 1958) serving Honey Pit (HER ref. 1956), Hill Pit (HER ref. 3952) and Meadow Pit (HER ref. 3953). "New Engine" is also shown on a plan of 1781, but not shown on the First edition Ordnance Survey plan of 1858, so was presumably out of use by this date.
