Wessex Archaeology was appointed to undertake detailed gradiometer survey over land at Riverdown Park, Bishopdown, Salisbury, Wiltshire (centred on NGR 414900, 132100). The project was commissioned by CgMs Consulting Ltd with the aim of establishing the presence, or otherwise and nature of detectable archaeological features. The work is required ahead of proposed development of the land in support a planning application for the creation of a new country park. The Site comprises two areas within an arable field to the west of Bishopdown, covering a combined area of 4 ha. The geophysical survey was undertaken between the 24th and 25th February 2016. The detailed gradiometer survey has demonstrated the presence of a number of anomalies of likely and possible archaeological significance alongside agricultural and geological features. The anomalies identified as being of archaeological interest are primarily ditch- and pit-like features, the most interesting of which is a possible enclosure ditch that has been identified in the south-eastern survey area. A number of pit-like features, which are potentially associated with this enclosure, may represent settlement activity such as post holes or rubbish pits.
