A possible partial curvilinear enclosure of unknown date, 19m to the south-east. This possible enclosure is partially masked by geology and is not completely clear, but would be approximately 50m in diameter. Also visible, 50m to the north of the ring-ditch is a series of small conjoined enclosures of unknown date, that abut or are truncated by the river. These enclosures are 35 in length, with no visble internal features. There are also a 3 linear ditches of unknown date. Helen Saunders (Essex County Council), February 2014. (S1-S2)
