Most of the buildings of this polygon are in institutional use. Includes 19th century school, Quaker meeting house, and 18th century houses and vicarage. 20th century housing clearance has reduced the density of the built environment with cleared areas reused for car parks and for construction of medical centre and nursing homes. Significant legibility of earlier boundary patterns and materials throughout. Notes in the SMR (file 119) postulate that this area, with the site of the church, may have represented the original core of Thorne with buildings occupying a putative southern bailey around the castle. Physical evidence of this theory rests on subsidence in a wall to the north of the school building photographed by Ryder in Nov.1980 and tentatively interpreted as resulting from the settlement of bailey ditch deposits. Documentary evidence quoted in the SMR -"Early 17th century documentary references suggest that important medieval buildings stood south of the motte. Casson (p27-28) quotes references to the "Hall Garth" (evidently to the l~est of the church), the "King's Chamber" and the "Chamber over the Outward Gate". The "Gate House" evidently stood in Stonegate not far from the church. The presence of an important group of buildings with a specific gatehouse, in this situation, would suggest that the Peel Hill motte may have had a bailey to the south. The parish church may have developed from the castle chapel, as evidently happened at St George's Church, Doncaster." (SMR PRN 119) Significant legibility of earlier boundaries and built features.
