Possible Iron Age or Romano-British enclosure, visible on Google Earth from 2015. 42m x 43m. Hut circle, east facing entrance, possible projecting linear. There are other cropmarks in the same field.
In 2018 a magnetometer geophysical survey conducted in advance of a proposed residential development identified a Iron Age/ Romano-British enclosed farmstead including potential enclosure ditches, roundhouse ring-ditches and a round barrow. In 2019 an archaeological evaluation resulted in the identification and excavation of later prehistoric to Romano-British ditches, gullies and pits. These are interpreted as being evidence of small enclosed farmsteads, ring-ditches associated with roundhouses and occupational debris. In addition, three sherds of undecorated Iron Age to Romano-British pottery were recovered.

Gullies located 1.9m apart were discovered during an evaluation at Woodside Lane, Ryton. They are thought to represent drainage features either side of a former wagonway. However, no structural remains of the wagonway (trackbed, sleepers or rails) survived.

A ropewalk is shown on John Rennie's 1826 Survey of the River Wear. The line is preserved in the road layout as Millennium Way.

The NER goods shed/warehouse was built on the east side of the northern end of Hay Street towards the end of the 19th century. A substantial part of Hay's Ropery (HER 17571) was demolished to make way for the extended goods yard. This warehouse survives in good condition. First shown on Ordnance Survey second edition of 1898. Rectangular red brick building with large arched openings. Currently in use as Ward Bros (Steel) Ltd.

By 1919 Hay's Ropery at the southern end of Hay Street had been demolished and replaced by a warehouse connected to a goods shed by a footbridge.

North Eastern Railway stables, built in 1883-84. Horses remained essential to the smooth operation of the railways, and many of the major Victorian urban stations (such as Salford and Camden) had stables. Horses were used for transporting goods to and from the goods yards, and for hauling track and timber. In some cases carriages for public hire were also kept in the same facility.

Railway stables. 1883-84, altered c. 1930. Designed by William Bell for the North-Eastern Railway Co. Ltd.. Red brick with blue brick and ashlar dressings and Welsh slate roofs. All openings have ashlar lintels. Entrance facade has 11 window, 2 storey central section flanked by single storey 11 window wings. Large central archway has segmental red brick arch with ashlar and blue brick dressings. Over central arch a moulded ashlar eaves band and above a dormer with a circular window and a half-hipped roof with decorative barge-boards. Arch has cast iron wheel buffers at base. Either side are 8 stable windows with ashlar lintels above a continuous blue brick band. Upper floor has 5 larger stable window openings to either side, also with ashlar lintels and also linked by a continuous blue brick band. Inner facade has similar central archway topped with similar dormer. Either side are two stable windows, them two large garage openings with two pairs of garage doors - inserted c. 1930. Beyond are two further stable windows and single stable doors. Above two larger window openings either side, then a loft doorway topped by a hoist under a dormer roof, and beyond 3 further large windows. Either side the single storey wings have a single boarded opening, an inserted garage door, a further boarded window a plank door with overlight and then three further boarded windows. Inner courtyard contains Horse Hospital block with asphalt roof. South facade has 3 stable doorways with over-lights and alternating with two stable windows, above 5 larger windows. North facade symmetrical with central stable doorway flanked by 2 glazing bar sashes to each side. Above a central loft-door topped by a hoist under a dormer roof, flanked by smaller windows. To south a single storey Van Shed added c. 1912, with large continuous garage doors and a slate roof. To north a single storey stable range converted to motor workshops, with 3 inserted sets of garage doors and two former stable windows to left.

Hay's Ropery, located to the west of Monkwearmouth Station, replaced the old ropery on the junction of the Newcastle and South Shields Road. The long narrow open workshop, for stretching and twisting hemp, ran north to south along Kingfisher Road (later Hays Road), measuring 280m in length. The proprietor was H.R. Hay. Cordage was required by the shipbuilding industry. Ropery frames are shown on the 25 inch OS map in the area of the later goods yard, between the station and earlier waggonway. The ropery provided a central axis along which were set out a series of new roads, combining small industrial premises with residential workers terraces. On the east side of the works was Ropery Row and Edmondson's Street. A large part of the ropery and these streets were demolished in the 1890s when the railway goods yard was extended (HER 17573). The ropery remained in production, retaining the block at the southern end of Hay Street, and some of the frames are still shown on the 25 inch OS. The contraction of the works was probably due to the widespread use of wire rope by this period. First introduced into England in the 1830s, wire rope had largely replaced hemp by the end of the 19th century.

Despite later disturbance, archaeological remains associated with the ropery may be preserved along the west side of the former goods yard, now the Sunderland Association Football Club orange car park. The current stone boundary wall may be the west wall of the ropery.

Bridge Foundry is shown on Robson's map of 1827. The iron foundry was owned by J.W. Thompson in 1856. The ironworks on the River Wear mostly produced castings for the shipbuilding industry. Bridge Foundry remained in operation until the mid 20th century. The layout of the complex changed little over the years. In 1915-17 there were plans for a new works to replace the complex, probably prompted by the increase in demand brought about by the war. But the development appears not to have been implemented, perhaps as a result of a fall in production after the First World War.
Some upstanding external walls of the foundry were recorded by Northern Archaeological Associates in 2017. Some retained evidence of arched doorways and other blocked openings, and there were boundary walls of various phases. The earliest phase of build was characterised by the use of locally sourced Magnesian Limestone rubble, bonded with lime mortar. The later phases are primarily in brick (hand-made and modern machine-made red brick).
The walls were also assessed by geologist Brian Young as they contain a remarkable variety of constituent components including natural rocks. Most of the walls are dominated by blocks of pale cream coloured limestone but there are also substantial amounts of sandstones of various types. Most prevalent is the Concretionary limestone - the distinctive 'cannon-ball' limestone common to the Sunderland area. It was quarried in large quantities at Fulwell and Carley Hill. The sandstone is characteristic of those associated with the local Coal Measures rocks, underlying the Magnesian Limestone. This outcrops along the banks of the River Wear a few kilometres upstream from the site. A small number of distinctive coarse-grained pink granite blocks were observed in the foundry boundary wall and the wall on the west side of Easington Street. There are no granite outcrops in Sunderland, but the material may have been brought in as ballast. The other exotic was a single block of coarse-grained pinkish feldspathic gneiss, seen in the foundry wall.
Archaeological evaluation in 2017 recorded a rectangular brick structure 1.25m x 0.4m laid on a concrete platform, probably the remains of a roof-supporting pillar. Internal structures relating to the casting process were found. There were two corroded cast iron plates. A deposit of slag was cut by a rectangular structure. The upper surface was concrete and the sides were made from cast iron plate with handles on the east and west sides. Full excavation is required. During archaeological monitoring of geotechnical pits and boreholes in 2018, 18th and 19th- century pottery, saggars and wag clay were encountered. In addition to demolition rubble and fragmentary wall remains.

Two unnamed buildings are partially drawn on John Rennie's 1826 Map of Sunderland, presumably under construction at the time of the survey. Robson's map of 1827 shows the pottery complex near to completion. The final layout is shown on Stephenson's 1829 Map of Sunderland. Bridge Pottery, known locally as Jericho Pottery, was a small concern manufacturing brownware. It is thought to have been built for Samuel Moore, who had bought Southwick Pottery around 1803 and changed its name to Wear Pottery. Alternatively Bridge Pottery could have been built for William Barker, earthenware manufacturer from Monkwearmouth, listed in Parson's Directory of 1827. The pottery chiefly produced brown glazed ware including bread mugs, stew dishes, flower pots and candlesticks and glazed white pots. The firm was contracted to the government to produce brownware. They exported pottery for the dairy market in Denmark and produced a range of goods for the home market, chiefly sold in the south of England. By 1861 the Bridge Pottery had been taken over by R.T. Wilkinson and leased to Messrs. Glaholm and Robson. It was later taken over by John Patterson. Around 1896 Bridge Pottery was sold to J.W. Snowdon & Co. Production moved to the nearby Sheepfolds Pottery (HER 2752) in 1900. In the early 20th century the two kilns were demolished and the adjacent U-shaped building was converted into a warehouse. By 1955 the Bridge Pottery (later warehouse) was a sheet metal works.
The upstanding remains of Bridge Pottery were recorded by Northern Archaeological Associates in 2017. The remains included a warehouse, the lower courses of which were the stone walls of the pottery. The upper courses had been rebuilt in brick. In addition there were a series of external walls, some which retained evidence of arched doorways and other blocked openings, and boundary walls of various phases. The earliest phase of build was characterised by the use of locally sourced Magnesian Limestone rubble, bonded with lime mortar. The later phases are primarily in brick (hand-made and modern machine-made red brick).

Archaeological evaluation trenching in 2017 recorded the walls of the pottery building, a kiln base, floor surface and other internal features. 58 pottery sherds of late 18th or early 19th century and saggars were collected. Full excavation of the site is required. During archaeological monitoring of geotechnical pits and boreholes in 2018, 18th and 19th- century pottery, saggars and wag clay were encountered. In addition to demolition rubble and fragmentary wall remains.
