The evaluation fieldwork comprised the excavation of 30no 30m x 1.8 trenches. These trenches provided a c. 3% sample of the application site. They were located to test geophysical anomalies and to provide a representative sample of the remainder of the site. Trenches were set out on OS National Grid co-ordinates using Leica GPS. Overburden was stripped from the trenches by a mechanical excavator fitted with a toothless grading bucket. All machining was conducted under archaeological supervision to the top of the natural substrate. Archaeological features/deposits were investigated, planned and recorded. Deposits were assessed for their palaeoenvironmental potential but no deposits were identified that required sampling. In February and March 2025, Cotswold Archaeology carried out an archaeological evaluation of land east of Webbs Court, Lyneham, Wiltshire. A total of 30 trenches were excavated. The evaluation recorded four ditches and three postholes, as well as a small number of furrows. One ditch contained Iron Age pottery. The other ditches and the postholes were undated artefactually and remain of unknown date and function, although one ditch was cut into the subsoil and is presumably post-medieval or modern in date.
P Busby (2025) studied this question.
