Salford Archaeology (SA) was commissioned by Norton Priory Museum and Gardens to run a community archaeological excavation on the site of Halton Castle, Runcorn. The excavation formed part of the HLF funded Halton Castle Project designed to further investigate the archaeological potential of the site and engage the local community. The purpose of the excavation was to further investigate the archaeological remains associated with the medieval and post-medieval activity on the site. The current work was informed by a previous excavation conducted by Robina McNeil in 1985/6. The findings from this excavation will inform the future treatment of the Scheduled Area and enhance the presentation of the site to the wider public.
