Trench One revealed evidence of an outer wall and cellared basement of a brick building, with probably boundary wall and potential outbuilding aligned with St. John’s Lane to the southeast. Although there was no artefactual evidence, the buildings most likely date to the mid-late 18th century, corresponding to the buildings shown fronting St. John’s Lane on the Hall and Pinnel map of 1796.the potential for the preservation of at least three distinct phases of activity in the vicinity of the Project Site. Trenches 1, 2 and 3 revealed remnants of structures belonging to the mid-19th century planned farm, sealed beneath the 20th century concrete surface. Clear stratigraphic relationships were recorded between these features and the earlier phases of development in all three trenches. The preservation of features was noted across the width of the project site, with pre 19th century features preserved at a depth ranging from 320mm-1.2m below the current ground level.

The development area was located on the site of the former Horsley Gaol (c. 1790 – 1880) and is also alleged to be the site of a Medieval Priory. Significant remains were revealed during initial groundwork on site. A full excavation of the development footprint was subsequently carried out as part of additional mitigation works required to discharge the condition of planning.

The programme of archaeological investigation was successful in revealing significant evidence of the mid-19th century Female Wing belonging to Horsley Prison. Potential evidence relating to the use of the site in the Medieval period was also identified.
