Summary

Archaeological work between 2021 and 2023 uncovered some limited evidence for prehistoric activity at this location. An initial geophysical survey of these fields in 2021 identified a number of scattered linear and discrete anomalies. Several fragmentary linear anomalies at the western end of the northern field were possibly associated with a group of potentially medieval trackways and enclosures identified to the west (NHER 65133). Two other linear anomalies probably represented features associated with former post-medieval field boundaries. The remaining anomalies were all of uncertain origin. Subsequent trial trenching in 2023 uncovered various scattered pits and ditches, the bulk of which produced little or no dating evidence. Notable exceptions included a pit containing a substantial quantity of Middle Bronze Age pottery. Small amounts of Late Bronze Age/Early Iron Age pottery were also recovered from several other pits and ditches and it is likely that at least some of the poorly dated remains were associated with these phases of prehistoric activity. The limited evidence for subsequent activity on the site included a small assemblage of Late Iron Age and Roman pottery, at least some of which was probably residual within later features. Two ditches were associated with former field boundaries shown on 19th-century remains

February-March 2021. Geophysical Survey.
Magnetometer survey of part of large proposed development area (Areas 6 and 7).
This survey identified a number of scattered linear and discrete anomalies, although none were of definite archaeological significance. The more interesting responses included a curving line of fragmentary linear anomalies in the north-west corner of the site. These may be related to an area of probable medieval settlement identified in the field to the west (NHER 65136); potentially continuing the line of a possible trackway that forms the northern boundary of a linear arrangement of plots or enclosures.
Two parallel north-to-south aligned linear anomalies in the northern field may also represent infilled ditches. Although these don’t correspond with anything shown on the available 19th-century maps, their orientation and the fact that they don’t continue into the adjacent fields strongly suggests they were associated with former post-medieval boundaries.
The remaining anomalies are of uncertain origin.

February-June 2023. Trial Trenching.
Evaluation of part of large proposed development area (Trenches 93-128).
The 33 trenches excavated at this located revealed a range of scattered ditches, pits and other discrete features, the majority of which produced little or no dating evidence. One particularly notable exception was a pit containing nearly 400 Middle Bronze Age pottery sherds (the bulk from a single Deverel-Rimbury barrel-shaped vessel). This feature had initially been identified as a possible cremation burial but samples taken from its fills produced only a small amount of burnt bone (which was probably animal). A square trench extension dug around this feature revealed a second pit, which, despite 100% excavation, produced only a single Late Bronze Age/Early Iron Age pottery sherd and fragments animal bone and fired clay. Samples from its fill produced no burnt bone and little of interest in the way of charred plant macrofossils. Small amounts of Late Bronze Age/Early Iron Pottery were recovered from a number of other features, including a shallow pit and three ditches (all of which displayed differing alignments). One of these ditches also contained a Late Iron Age pottery sherd, while a second Late Iron Age sherd was residual within a second, similarly-aligned ditch that was almost certainly a much more recent feature.
The limited evidence for subsequent activity of the site included two Roman pottery sherds, which were both recovered from one of two large pits recorded in the central part of the site.
Features of more recent date included two ditches that appear to have corresponded with former field boundaries shown on the Ordnance Survey First Edition Six-inch map (S2), one of which contained medieval/post-medieval roof slate fragments and the other a post-medieval iron bolt.
The remaining features were all undated. The more notable of these remains included a shallow circular pit containing dumps of heat-reddened clay and dark, charcoal-rich material containing much burnt flint. A sample from this feature produced charcoal but else in the way of charred plant macrofossils.
