Redcliff Quarter 2: Redcliff Street and St Thomas Street, Bristol. Additional Archaeological Evaluation: Phase 1
Bibliographic record
Abstract
The fieldwork comprised the excavation of ten trenches (numbers 25-34) in the locations shown on the attached plan. The exact locations of a number of trenches were altered slightly from the original proposal agreed in the WSI due to a variety of constraints, with the approval of Peter Insole. Trench 26 was not fully excavated, the northern half being omitted due to access requirements, although the trench was extended westwards to define the extent of a modern cellar. To the centre of the site, Trench 28 was located wholly along the length of a deep modern cellar. The eastern part of this trench was moved southwards so as to enable an investigation of an intact sequence of earlier deposits identified just beyond the footprint of the cellar. The presence of an existing site car park, and a brick and concrete fuel tank, to the west of the site restricted the northern extent of Trench 29. Trench 33 was moved a few metres to the north, away from the site boundary. The site entrance was directly adjacent to Trench 31 so that to continue safe access and egress to the site, the western end of the trench was moved to the north. These alterations to the trench locations were not detrimental to completing the aims and objectives, and in some cases provided a clearer window through undisturbed archaeological deposits, down to the underlying alluvial substrate. Archaeological monitoring of the removal of an 'Interceptor Tank' by contractors was also undertaken and is included in the results of this report. Trenches were set out on OS National Grid (NGR) co-ordinates using Leica GPS and surveyed in accordance with CA Technical Manual 4 Survey Manual. An archaeological evaluation was undertaken by Cotswold Archaeology in September- October 2017 at Redcliff Quarter, Redcliff and St Thomas Street, Bristol. Ten trenches were excavated. Evidence of activity from the early 12th-century occupation of Redcliff through to the modern period was identified during the evaluation. Medieval activity comprised the setting out of plots on a north-east/south-west axis, fronting onto Redcliff Street to the west and St Thomas Street to the east. A historic boundary, the 'Law Ditch' formed the rear property boundaries, though no evidence of an earth-cut ditch was identified. Instead, evidence was uncovered for the culverting of the Law Ditch within a pair of stone-built revetment walls during the medieval period, with further enhancements during the post-medieval and modern periods. The evaluation also uncovered evidence for small-scale industrial activity at the rear of the Redcliff Street plots during the medieval period, in the form of the partial remains of a probably dye-vat base. A Victorian kiln or furnace with two fireboxes was also excavated near the corner of Redcliff Street and Three Queens Lane. The function of the kiln/furnace was unclear, and although kiln spacers found in a nearby trench during the evaluation were of a type used in pottery and clay tobacco-pipe manufacture, vitrified slag recovered from the base of the structure also suggests the possibility that it was an iron foundry. Post-medieval cellars were identified belonging to properties on both Redcliff Street and St Thomas Street. Despite a large amount of truncation by post-medieval and modern features, the medieval archaeology was generally well preserved, where it survived, with the most intact area of medieval features and stratigraphy located in the south-west of the site.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
