Detailed magnetometry was carried out over 28ha within areas of the country park ahead of tree planting using a hand-pushed cart-based system of 5 sensors spaced 0.5m apart. Just beyond the north western part of the site lie the scheduled remains of a Roman villa, and the survey has located a number of anomalies that are highly likely to be associated with it. These include a square, double-ditched enclosure that could have some ritual function as well as evidence for enclosures, pits and a ring ditch that are associated with settlement likely from the Iron Age into the Roman periods. Within the area of parkland to the east are two linear ditches that appear to have been truncated by later boundaries and possible quarrying. A number of pit-like features have also been located, although it is not clear if they are associated with tree throw pits/removal, former quarrying or if they have some archaeological potential. Ridge and furrow and a response to existing and former parkland tracks have also been recorded. Elsewhere, the survey areas contain ridge and furrow and a small number of linear anomalies, many of which appear likely to be associated with drainage. The infilled branch line cutting in the southern part of the site is associated with highly magnetic debris relating to steel and iron objects.
