An archaeological evaluation was carried out at the Guildhall Feoffment Primary School, in Bury St Edmunds, Suffolk. Two trenches were excavated, revealing a series of medieval quarry pits. Post-medieval quarry pits were also excavated, as well as pits of uncertain function. Two postholes were recorded and these may have been medieval or post-medieval. Layers of post-medieval garden soil and a series of late post-medieval surface or levelling deposits were also excavated across both trenches, sealing the features. Finds included pottery (Late Saxon, medieval, post-medieval and modern), medieval and post-medieval brick and tile, post-medieval window and bottle glass, slag, animal remains and oyster shell, as well as undiagnostic struck flint. The features were generally well preserved under the garden soil and the environmental samples produced evidence of cereal processing (possibly including malting) or the use of cereal waste for kindling, as well as wood charcoal, and hammerscale residues. This material suggests that agricultural, industrial and domestic activities were likely to be taking place in the vicinity.
