 An ancient settlement site 600m east of Cedar Court has been identified from aerial photographs, though nothing can be seen on the ground.The area around Alderton was once a stronghold of Catholicism, and within the grounds of Alderton Hall stands an ecclesiastical building, possibly a chapel or refectory dating back to the 12th century and believed to be part of a group of buildings built by the Augustine monks who controlled much of the land on the Bawdsey Peninsula at that period.Alderton Hall boasts both a priest's hole (a hiding place created for dissident Catholic priests during the purge which followed the Reformation) and a secret passage leading to the neighbouring church of St. Andrew's.
