This report describes the results of an Archaeological Watching Brief which was carried out by MAP Archaeological Practice in July 2020 prior to the erection a single storey extension on land at Thorndale Farm, Wintringham, North Yorkshire (NGR SE 87892 73410). Although the excavation work associated with the footings of the extension were carried out without archaeological supervision, the partial sections and spoil heaps were available for visual assessment during the subsequent site visit. Excavation of trenches associated with the drainage for the extension was carried out using a mechanical excavator under direct archaeological supervision. No archaeological finds, features or deposits were identified on the site.
