Williams for Holmesdale Archaeological Group, Reigate and Banstead Archaeological Co-ordination Committee and SyAS revealed features of 12th century date, and later medieval and more modern features. Further excavation by D.W. Williams and by D.G. Bird for SyAS and DOE revealed a large part of the plan of the medieval and later vicarage. (140 and 151)
