An archaeological watching brief was undertaken during installation of a new water main. The monitored works comprised the excavation of three trenches in the eastern fields of the works route, which covered 0.77 hectares and was north of Abbey Lane, Aslockton, Nottinghamshire. Two of the three trenches were monitored and recorded during mechanical excavation. The other trench was excavated prior to commencement of the watching brief, and though part of the trench was re-excavated with a machine, the presence of any archaeological remains could not be determined. There was little artefactual material recovered from the site; the earliest datable artefact was a residual prehistoric flint recovered from the subsoil in one trench. Agricultural soils containing pottery and animal bone dating to the medieval and post-medieval period respectively were also recorded in the trench, as well as a post-medieval brick post pad. Undated cut features were uncovered in two of the trenches, comprising pits, a posthole and a ditch. The proximity of these monitored trenches to a known site of Iron Age/Romano-British occupation indicates that they could be part of this activity, perhaps on the periphery, though a lack of any artefact or ecofact evidence makes any further conclusions difficult.
