An archaeological watching brief carried out by University of Leicester Archaeological Services (ULAS), at The Mill Wheel, Ticknall Road, Hartshorne, Derbyshire (NGR: SK 3256 3213) in advance of the construction of a two storey extension. A Written Scheme of Investigation (WSI) had been prepared by The Historic Environment Consultancy on behalf of the client, The Mill Wheel (Hartshorne) Ltd., and ULAS carried out the fieldwork in accordance with the WSI and CIfA guidelines. The development area consisted of a 50 square metre area at the rear of the existing building, currently a back yard. The development area lies on the site of a former water mill and associated industries which was in use from at least the 17th century until the early 20th century. The watching brief was undertaken as there was potential for below ground archaeological remains relating to former use and associated water management. However during the watching brief no archaeological remains were identified. The archive for the site will be deposited with the Derbyshire HER with the accession ULAS_MillWheel19.
