A detailed magnetometer survey was undertaken within two land parcels at Chesterton, near Bicester in Oxfordshire. The results indicate the presence of cut features of archaeological potential in the form of a rectilinear enclosure and linear ditch. These extend across both survey areas, although the north eastern area contains widespread magnetic debris which may have obscured further weaker features. Several other linear and discrete anomalies have been located, and while these may relate to cut, ditch-like and pit-like features they are weak, fragmented and indistinct.
