Due E (of Castle Hill), 220ft distant, are the remains of a work, pear-shaped in plan, consisting of a vallum which possibly joined the SE angle of the camp. (1)
The central work, now demolished, has on (2) the look of a Civil War battery (note also the proximity of the church; a possible observation post) but no historical substantiation was found in local research. (3)
See M2415 for Castle Hill, M5188 for fishponds.
