Stone retaining wall with brick elements located to the rear of the main buildings fronting onto High Bridge Street. The wall separates the higher area of Half Moon Yard to the west from a lower yard on its eastern side. The wall is first illustrated on Oliver's map of 1830 apparently as a dividing wall between two adjoining ranges arranged along this line. The wall was originally constructd in uncoursed, roughly squared masonry, with a distinct batter, making the wall wider towards its base. This would indicate that the wall has always retained the ground behind it, rather than this ground being built up against it. Two brickwork elements have been added to the wall at its southern extent and close to the centre. These relate to later structures built over and onto the earlier wall. Four brick-arched, bricked up, fireplaces survive along the length of the wall. The wall also contains three buttressing pilasters, one in brick and two stone. The fireplaces match with rooms illustrated on the 1858 OS map.
A wall to the north side of the rear yard is later than the retaining wall and appears to be a basement wall. Again the positioning of features on this wall relate to building ranges on the 1858 OS map. It is clear that both walls were lower ground floor or basement walls built to retain ground to the north and west of the yard as well as provide one face to the rooms of buildings along the side of the yard.

These buildings were recorded in 2013 by ARS. No 25-29 appears to have been built between 1884-1886 - replacing earlier buildings. They appear to have been used as the offices and production area for two local newspapers which first appear in Kelly's directory of 1886. Printing rooms and warehouses associated with this function were located in the courtyard behind the building, whilst living accommodation was provided at attic level for the caretaker. It is subsequently referred to as 'High Bridge Buildings'. From the 1926 directory High Bridge Buildings seems to have been incorporated into Ward's Buildings which stretch as far as no.39. Several developments on the ground and first floor levels of the building are associated with the conversion of offices to shops on the ground floor and of individual offices to an open-plan layout on the first floor. Aside from these aspects the building retains a significant proportion of its original features including fireplaces, timber panelling, bannister and cornicing.

The building was recorded in 2013 by ARS. No 23 as constructed between 1886-1898 (more likely closer to 1886) replacing earlier buildings. It is difficult to recognise in the trade directories due to renumbering and demolition of buildings on the street. Fire Insurance Plans of 1927 state that the building was in use as a clothing warehouse. The ground floor may have originally functioned as a shop as the present shop front appears original. A number of original features, including a fireplace, exist on the first floor.

These buildings were recorded in 2013 by ARS. No 15-21 appears to have been built c.1927 - replacing earlier buildings. They appear in Ward's directory 1928 as High Bridge House. (In earlier trade directories No. 15, 17, 19 and 21 are listed either seperately or in pairs). By 1938 it had eleven occupants engaged in various trades including carpet manufacturing, warehousing and retail. This building is of Art Deco style and is 6 storeys in height with a flat roof. The main entrance into No.21 bears a black marble plaque with 'High Bridge House' written in white. Two small granite steps lead up to the door the first of which also bears the name 'High Bridge House'. Internally the building has lost the majority of its internal fixtures and fittings. Several stud partition walls have been inserted to create office space and openings have been created between this and adjoining buildings at first and second floor level.

Multi-phased enclosure settlement typical of the coastal lowland Iron Age in south Northumberland. Radiocarbon analysis shows that the site was occupied, at least intermittently, throughout the Iron Age, and may have origins in the late Bronze Age. The earliest evidence for activity on the site come from a radiocarbon date taken from oak charcoal from the fill of a roundhouse ditch 5968-5750BC although this may represent evidence of transient late Mesolithic activity. The settlement is sub-rectangular in shape, defined by a large ditch. It comprises thirteen roundhouse plots, often reused several times, probably with two or three houses inhabited at once. Ploughing has removed most of the evidence for structural features such as postholes, wall slots and floors. The principle surviving features are deep penannular ditches defining each plot. An intermittent gully around the settlement is indicative of a timber palisade enclosing the site. This has been radiocarbon dated to the early Iron Age. Later, a double-ditched enclosure with a sub-enclosure in the southern part was constructed around the settlement. Palaeoenvironmental data indicates that spelt wheat and 6-row hulled barley were the main cereal crops used at the site. An unusual 'fire-shovel' was found by ASUD during the archaeological investigation, likely to have been a multi-purpose hearth tool - possibly a high status item. Other finds included prehistoric and later pottery, flints and quern stones. The settlement was abandoned around the turn of the millennium, probably before the Roman incursion.
Occupation phase 1: A curvilinear gully can be assigned to a period of possible early un-enclosed activity on the site. It may be the remains of a roundhouse ring-gully representing very early Iron Age, or possibly late Bronze Age settlement.
Phase 2: After the phase 1 feature was out of use and backfilled, an oval palisaded enclosure was constructed. An inner palisade may have also existed. It is proposed that the outer palisade enclosed an area c.45m x 40m, and the inner palisade an area of c.25m x 20m. The palisades may have been used contemporaneously. One roundhouse is located within both palisade enclosures.
Phase 3: Phase of probable unenclosed settlement. This phase comprises three possible roundhouses and several ditches and gullies. Despite the removal of the enclosure palisades, the settlement remains centred in the same place. This open settlement may have begun as early as the 8th century BC.
Phase 4: Open settlement. Several roundhouse ring ditches were completely re-dug on the same plots. Radiocarbon dates indicate short lifespans for the houses. Some evidence for the spread of houses away from the nucleus.
Phase 5: No radiocarbon dates. Several roundhouses assigned to this phase by ASUD.
Phase 6: Probable that enclosure of this site occurred in the late Iron Age contemporary with neighbouring settlements. The earlier outer ditch was superseded by a linear boundary ditch along the west side and the inner/sub-enclosures along the south. C. 200-100BC
Phase 7: Inner enclosure/sub enclosure. The outer ditch had been backfilled prior to the construction of the sub-enclosure. It is probable that the sub-enclosure was unoccupied as there is only evidence for a short curvilinear ditch which could have co-existed within it. The sub-enclosure was re-established several times, initially with fences, then later with recut ditches. Recovery of a mortar, pestle, organic remains and burnt bone may reflect processing or consumption of food within the enclosure. The east entrance through the inner enclosure ditches was 8m wide. A timber gateway probably led into the enclosure narrowing the entrance to 2.2m.
Phase 8: Two roundhouses represent the final phase of occupation of the settlement. C.100AD abandonment.
