A stone-lined well of exceptional quality. It was 7.8m deep and 0.75m wide. The lowest 2m had been excavated through bedrock. It had a rounded base. The stone lining was made of dressed stones. Four dressed blocks of the stone well-head were located at the base, suggesting demolition or destruction, and a near complete Buff White jug of likely late 13th century date, broken into many pieces. The fill was waterlogged from a depth of 3.80m. A finely dressed stone that would have formed the top course of the wellhead was recovered from a nearby ditch. The fill at the top of the well shaft contained clay pipe and brick. A complete cattle metatarsal was found in the well - estimated withers height of 1.12m, which is within the usual range for medieval cattle. A new born puppy was represented by bones recovered by hand and from sampling. Partial skeletons of juvenile domestic fowl and fragments of eggshell. Dated C14th.

Excavated in 2005 in advance of open cast coal mining. Before the grange was constructed a north to south boundary ditch and ridge and furrow was created. The ditch had a steep sided profile with a rounded base and was 1.14m wide and 0.60m deep. It was deliberately backfilled with mixed silty clay. No dating evidence was recovered from it. The furrows were filled by brown sandy silt. They were 1.60m wide and 0.04m deep. The ditch may date from the later 12th century, possibly representing an earlier access route to Prestwick Carr, which was later superseded by a cobbled road. In the mid 13th century a rectangular enclosure was constructed on a slight ridge. It was probably a grange (farm complex owned by monasteries). The grange was enclosed by ditches, with the main complex measuring 55m by 40m . The remains of at least two buildings survived in the interior. One of the buildings may have had a stone foundation or dwarf wall. The other was constructed on a frame of timber posts and contained a hearth stone. The enclosure also contained a stone-lined well of exceptional quality. Another enclosure was added to the south side and contained a large rectangular timber building, possibly a barn. There was a sunken cobbled area against the interior of the southern ditch, which might have been a purpose built retting pond for soaking bundles of hemp stalks to extract their fibres for use in manufacturing coarse fabrics, ropes and sails. Charred hemp seeds were found within the enclosure, associated with the latest phase of activity on the site. The grange was accessed by a substantial metalled road with wide flanking drainage ditches. In the field immediately north of the grange there was a causeway over the road ditches. West of the road there was a penannular gully that may have been a drainage feature around a stack-stand for drying peat. The fields west and north of this contained traces of east to west aligned ridge and furrow. Documentary evidence suggests that the grange was probably associated with Newminster Abbey, a Cistercian abbey on the outskirts of Morpeth. The Newminster Cartulary states that a grange at Horton and its turbary (the award of the right to extract peat) were provided with a stone road. The end of the grange in the second quarter of the 14th century (based on pottery evidence) was abrupt and possibly violent, as destruction deposits were recorded. The site may have been a victim of the plague, or a Scottish raid (in 1327 the township and turbary of Mason, 1.5 km to the south-east, was wasted by the Scots). Following the abandonment of the site, a ridge and furrow field system was created over it. The grange may have been re-established on higher ground at 'Old Horton Grange' 1 km to the north. Finds included 12th to mid-late 14th century pottery, a corroded mid 13th century 'short cross' silver penny issued by Henry III (c.1242-47), a worn 'Long Cross' silver penny issued by Edward I (1301-10). 250 pieces of wood were recovered (objects include a few stakes from a wattle structure, a peg and a ladder rung) and a leather sling pouch, which is a rare find and worth specialist study. Animal bones included cattle, sheep, pig and horse. Dated C13-14th.

During excavations in 2005, a curvilinear ditch was recorded. The fill did not contain any dateable artefacts, but a pig jaw from the base from the ditch was radiocarbon dated to 900 - 1030. The ditch may have represented a boundary or enclosure with an entrance from the south. The eastern limit of the ditch respected or at least did not transgress the prehistoric pit alignment (HER 13282). After the pig mandible was deposited, the ditch had silted naturally. The lack of artefacts within the feature suggests that the ditch was not located in close proximity to occupation. Dated C9-C11.

An alignment of rectangular and oval pits excavated in advance of open cast coal mining in 2005. The length of the alignment was 385m. The pits were sub-rectangular shape and between 1.5m and 2.25m long, 0.8m and 0.95m wide and up to 0.66m deep. The upcast from the pits was probably used to form a low earthen bank. It probably represents a prehistoric landscape boundary heading straight towards Prestwick Carr, which was at that time, a post-glacial lake. No dateable artefacts were found in the fill of the pits, but quartz from one pit was Optically Stimulated Luminescence dated to the Late Bronze Age or Iron Age (lower fill 920 BC +- 430), suggesting the date of the digging of the pits. The pits were allowed to silt up in the Romano-British period (upper fill 280 AD +- 130). Finds were: a flint flake, a perforated rectangular sandstone block (possibly a weight?), 90mm long, 80mm wide and 45mm deep, off-centre hole 10mm, found in lower fill of pit 2133) and a small thin greywacke stone disc with bevelled edges (56mm diameter, 5mm deep, found in fill of pit 2167).
The pit alignment did not show up in the geophysical survey of 2002 nor on aerial photographs. The pit alignment may have remained visible as a landscape feature in the early medieval period as a 10th century enclosure ditch respected its line. Other pit alignments have been found at Blagdon Park 1, Shotton North-East, Shotton Anglo Saxon Site (where an isolated Iron Age roundhouse was also found) and Castle View School at Hylton, Sunderland.

A turbary (right of digging peat) at Brenkley is referred to as land retained when grants were made to the monks of Newminster, Tynemouth Priory and the Nunnery of St. Bartholomew.

A turbary (right of digging peat) at Merdesfen is referred to as land retained when grants were made to the monks of Newminster, Tynemouth Priory and the Nunnery of St. Bartholomew. The turbary was described in 1325 as having its annual value reduced from 10s to 6d. A will of 1327 states that the whole township, along with the turbary had been wasted by the Scots. Dated C14th.

In the middle of the 12th century, Roger Bertram, Baron of Mitford, granted the township of Horton Grange with a turbary (right of digging peat) to the monks of Newminster. To support the turbary, right of access was granted across Roger Bertram's land, and a cart track was created to allow the peat to be taken from the turbary. This was one of the earliest grants to the monks of Newminster. The price of the grant was 140 marks, a hunting horse or hound to the value of 20 shillings and an annual rent of £10, payable at Pentecost. A field known as Gresside, which was possibly located on the boundary of Horton Grange and Prestwick Carr, was granted to the monks of Newminster by William de St. Peter. There is no documentary evidence for the use of the turbary after the Barony of Mitford was broken up after 1262. Dated C12th.

A rectilinear enclosure was identified through geophysical survey in 2007 and evaluation trial trenching in 2008. The enclosure is formed by gullies or shallow ditches. A number of flint flakes including a scraper blade were found within the ditches. Environmental results also suggest a prehistoric date for the feature (false oat-grass-tubers and hazelnuts were present). A limited amount of fuel waste and fragments of burnt and unburnt mammal bone suggest a background level of domestic waste associated with habitation. A trench excavated in the centre of the enclosure did not record any features, which suggests truncation.
The enclosure is situated on a small plateau near the crest of a hill on sandy soil. A fragment of charred hazel nutshell was radiocarbon dated to 4755 BP +/- 30. Another fragment was dated to 3005 BP +/- 30. The enclosure was fully excavated in 2010-11. The enclosure was 0.39 hectares in size. It was orientated approximately east-west and was formed by a single ditch along each side. Entranceways were found in the west and southern sides. The ditches varied in width and depth. The southern ditch was 1.70m wide and 0.60m deep at its eastern end and 2.10m wide and 0.28m deep at its western end. The ditch contained a single fill which contained flint tools. The sides of the ditches were sloping and it had a concave base. No internal features were found inside the enclosure.
TWM Archaeology suggests that the enclosure may have been used as a stock corral. This would explain the lack of internal features (although plough damage and natural erosion may have removed these). The entrances are unusually wide. Traditionally late prehistoric enclosures have a single entrance facing east or south-east. Here the entrances face west and south. TWM Archaeology suggest that cattle could have been corralled from the dry western part of the site into the enclosure, with the southern entrance leading towards water at the burn. Cattle require daily water. Sheep prefer more upland drier areas and they don't require large amounts of daily water. Flints from the site date from the Mesolithic period (a residual flint which pre-dates the enclosure) to the Bronze Age. Of special note is an Early Bronze Age fabricator or knife. Radiocarbon dates from charcoal from the ditch fills confirm a Bronze Age date for the enclosure. 2350-2130 BC, 2140-1930 BC, 1640-1490 BC, 1380-1120 BC.

Iron mission chapel served from Whitburn, recorded in 1894.

A T-shaped building with a projecting side porch. There was a steeple on the roof of the shorter wing. There were barge boards on the gable end and a probable dormer in the main roof. The gable apices were finished with turned posts. Inside there was a reading room, communal hall and union lodge room. The building was destroyed by fire in the 1930s.
