Description of two Bronze Age metalwork artefacts recovered from the conveyor belt at Elvaston Quarry in 1985, together with a human skull and various animal bones. The site was on low-lying land adjoining the River Derwent, and may once have been crossed by palaeochannels.

Excavations in the grounds of Bolsover Castle ahead of the construction of a new Visitor Centre revealed large post-pits belonging to part of an aiseld timber building. Finds from the post-pits and a nearby cess-pit suggest a probable domestic use for the building and a construction date in the first half of the thirteenth century. An alternative function as an administrative building is also suggested. The building fell out of use towards the end of the same century. Service trenches excavated during the construction work included on on the south side of the outer bailey bank, which penetrated a drystone wall set outside of the medieval rubble bank and positioned next to a re-cut of the bedrock, defining a deep ditch. The infill contained clay-pipe fragments dated to arround 1650--60, and possible kiln saggars. The wall and re-cut ditch were interpreted as part of the re-fortification of the castle during the Civil War. Includes reports on
