Seven Acres Park is a local nature reserve that follows the course of the Bradshaw Brook in the Breightmet area of Bolton, Greater Manchester. The nature reserve contains several sites of known archaeological interest, including a former industrial site that was known from the mid-nineteenth century as Tootill Bleachworks (centred on NGR SD 7375 0951). The site of this bleachworks has recently been the subject of informal intrusive investigation carried out by local enthusiasts, which demonstrated that important archaeological remains survived in-situ. However, Bolton Council, in consultation with the Greater Manchester Archaeology Unit, expressed concern that an appropriate record of the exposed remains had not been compiled in accordance with professional guidelines. In order to redress this shortcoming, a programme of community-based archaeological excavation was proposed by the Heritage Landscape Officer for Bolton Council in consultation with the County Archaeologist for Greater Manchester. In October 2009, Oxford Archaeology North (OA North) was commissioned by Bolton Council to facilitate a community-based archaeological investigation of the site. The work was carried out over a two-week period, and involved local heritage and wildlife voluntary groups, working alongside local residents. The excavation was intended to engage members of the local community with an interest in the site, produce a detailed record of the exposed archaeological remains, and to establish the potential of the site for further investigation and ultimate presentation as a monument to the industrial heritage of the area.
