This paper examines the cave systems of Worlebury Hill, North Somerset, drawing on an unpublished manuscript by the late Christopher Richards. It documents archaeological and palaeontological discoveries from sites such as Doorbar’s Swallet and Worle Quarry, revealing evidence of Pleistocene fauna and prehistoric activity. By integrating historical records, fieldwork, and overlooked sources such as local newspaper reports, the study highlights the value of diverse archival materials in reconstructing the region’s karst landscape and its archaeological significance.
