Archaeological Research Services Ltd was commissioned by the National Trust to undertake an archaeological watching brief during ground works associated with the installation of a new drainage system, within the stable yard and adjacent areas at Clumber Park. The watching brief was carried out to ensure that any potential archaeological remains on site encountered during the course of the groundworks were identified, characterised and recorded prior to removal. The archaeological features identified within the excavated areas revealed three distinct phases of activity, dating from the 18th-20th centuries. The earliest phase identified on site is associated with the construction and development of Clumber House, 1760 - 1938. In total, ten features were identified dating to this phase , including in situ floors and a brick vaulted chamber, various drainage elements, and steps that once formed an entrance to the terraced gardens adjacent to the main house. The next identifiable phase was associated with the demolition of the Clumber House, the majority of which was destroyed in 1938. The final phase of activity, dating to post-1940, consisted of a square brick structure and a dog burial which had been wrapped in a blue dress of c1910-940 (pers comm Simon Chesters-Thompson, National Trust Curator).
