A trial-trenched evaluation and small excavation in 2015, in advance of a housing development, defined a small number of late prehistoric (ditches, pits and post-holes), which produced a small assemblage of handmade pottery (incl. three decorated sherds) dated to the Early Iron Age. The excavation also defined a probable Roman ditch (containing a 2nd century AD sherd).
