Evaluation by J Aaronson of CA within the Scheduled Monument of Chertsey Abbey revealed a considerable amount of residual medieval material, including pottery, tile and brick that undoubtedly derives from Chertsey Abbey, but is believed to be material previously sifted out during excavations carried out in 1954. Gravel layers were also revealed that may have formed part of an earlier path skirting the south and western sides of the mid-19th century Abbey Lodge.
