Undated ditches found at Perse Schools rugby pitch, Cambridge

Between the 5th and 16th October 2012 Oxford Archaeology East was commissioned by The Perse Upper School to carry out an evaluation, and subsequent limited excavation, in advance of the construction of new netball courts at the Perse Upper School, Hills Road, Cambridge TL 4614 5569.
The trenches were excavated to a chalk natural and revealed a number of natural tree throws. These were cut by the later archaeological features and may relate to a tree clearance episode in the Early to Middle Bronze Age.
The trenches uncovered three separate alignments of ditches. The earliest aligned north-west to south east and was potentially prehistoric in date. A second alignment orientated west-north-west to east-south-east with associated north to south ditch was potentially Roman or medieval, with Latest Iron Age and Early Roman pot recovered from it's fills. Finally an undated system aligned approximately east-west.
An isolated post-hole of unclear date was also uncovered.
These features are likely to be of prehistoric date and are likely to be associated to the nearby Bronze Age field systems and settlement at Clay Farm, which lies to the immediate southwest of the site.
