An archaeological evaluation was undertaken on the land of the Scheduled Ancient Monument of Chertsey Abbey (SAM 23002). A total of 48 metres was excavated across five trenches. Four pits, possibly post holes, of uncertain date were identified to the southeast of the site. A possible Saxon feature was uncovered which may be part of a linear boundary ditch running west to east across the site. A possible medieval boundary was identified to the north of the possible Saxon ditch and is believed to run parallel though this could not be confirmed. Compacted gravel was found which may have been a surface associated with a medieval building which is now demolished. A demolition deposit was uncovered across the site which is believed to relate to the demolition of the manor house and its associated buildings. A modern pit was found to have destroyed archaeological deposits in part of trench 1 but all other archaeological deposits were well preserved with modern disturbance confined to the upper deposits
