Two fragmented parallel ditches of uncertain date seen as cropmarks and mapped from aerial photographs taken in 2011 as part of the English Heritage: Hoo Peninsula Landscape Project. The ditches are aligned WSW-ENE and can be traced for c.125m and lie between 3.3m and 4.3m apart. It is possible that they represent the remains of a later prehistoric boundary or a narrow trackway associated with the cropmarks of enclosures noted to the east and north-east (also cropmarks photographed in 2011 by English Heritage). The ditches pass through an incomplete ring ditch, possibly a Bronze Age round barrow.
