Ridge and furrow of Medieval or Post Medieval date seen as earthworks and mapped from air photographs. Most of these remains still survive. There is particularly good earthwork survival from the west beside the River Don, on Boldon Flats and to the east in the area of Cleadon Hills Farm. Other remains have been destroyed by development in Cleadon and Boldon. A small area of ridge and furrow north of Mundles Farm on Mundles Lane, East Boldon (NZ 3662 6011), is on South Tyneside Council's Local List. The ridge and furrow north of Cleadon Hills Farm is also on the Local List. Surveyed as part of a ridge and furrow project by ASUD in 2013. The report concluded that the narrow ridge and furrow suggests cultivation continued on from the medieval into the post-medieval period on the common fields. Later field boundaries overlying cultivation remains may date from enclosure c.1658.Ridge and furrow varies in size between c.3.5-6m between the crowns of ridges and c.0.1-0.3m in height. Several banks were also recorded which may relate to upcast from drainage ditches or used as boundaries. To the east, north-south orientated furrows with a wavelength of c.5m were found during an evaluation at Albert Elliot School. To the south of Cleadon Hills Farm the R&F has been ploughed out but the line of the S-curve is preserved in boundary walls.

A military depot of Second World War, seen on war-time air photographs. Two groups of structures at NZ 3952 6398 and NZ 3966 6371, approximately 300m apart are probably magazines of ammunition associated with a naval gun known as the Tyne Turret which was situated approximately 700m further east. These were all temporary structures protected by coils of barbed wire. Now demolished.

Probable field boundaries of Medieval or Post Medieval period seen as cropmarks on air photographs. Seen at the top of hill slopes south-east of Washingwells and visible over a distance of 150m north to south and 70m east to west.

Shafts, probably of Post Medieval date, seen on air photographs. Look like bell pits. They run down the hillside, over a distance of 300m east to west and 350m south-west to north-east, towards a dismantled railway. Now levelled.

Two circular cropmarks, possibly post medieval shafts, seen on air photographs. Located at the top of hill slopes south-east of Washingwells. Look like bell pits.

Ridge and furrow of Medieval or Post Medieval date seen and mapped from air photographs. Some of the earthworks still survive, but many have been levelled or built over. Earthworks survive adjacent to Dunston Hills coal pits (SAM 30928).

Seen on air photographs. Formed by concentric circles of posts used for mooring balloons. Approximately 22m in diameter. Associated buildings - two buildings 18m to the east, and another 24m to the west-south-west. Two vertical war-time photographs show a balloon drifting near the mooring site; one military oblique photograph shows a balloon on the ground moored on the site. Now destroyed by development.

Post medieval ridge and furrow seen on air photographs. Levelled and built over.

Barrage balloon of Second World War seen on air photographs. Close to the River Tyne at South Benwell. A circular concentric arrangement of posts, 21m in diameter, for the mooring of balloons. Destroyed by development.

Five air raid shelters of Second World War seen on air photographs. In school playing fields between Condercum Road and Conhope Lane. Arranged north-south surrounded by banks on all four sides. Each shelter was 15m x 7m. The whole complex was 90m x 25m. Now levelled.
