Author: SUMO Survey with Graham Keevill, Cathedral Archaeologist


A Ground Penetrating Radar (GPR) survey was conducted over approximately 1900m² at the Cloister and Chapter House of Rochester Cathedral, along with the site of the medieval dormitory – now a courtyard to the Old Deanery. Numerous anomalies were identified across the site. They are probably associated with the Chapter House dated between 1080 and 1100, the arrangement of the early Norman Cloister and Garth, the Chapter House dated between 1120 and 1150, the 1805 Prebendal House, Dorter Range and medieval buildings. Evidence of tree roots and potential services were also revealed.
