Summary

West of Sonning Common within Wyfold Wood, situated on a slight rise, an irregular oval shaped site enclosing c. 2.1ha. On the 1st ED. OS map. Univallate with a counterscarp bank, damaged by some gravel quarrying and tree planting especially to the N and W, and by a woodland boundary bank on the SE side. Rampart survives to c2. high in places, counterscarp bank to c.1m. Original entrance at the SE, an oblique passage way, ramparts to the N appear to enclose a spring, now a pond. Possible internal quarry hollows. No interventions and no dating evidence.

Land Use

Extensively mutilated by gravel digging and tree-felling, especially to the N and W. Along the SE side, the counter-scarp of the ditch has been destroyed by the construction of a woodland boundary bank. The N part of the earthwork, much reduced and masked by rhododendron bushes. Tree and brush cover over most of the site.
