Although it was not obligatory to record archaeological sites until 1816, many draughtsmen displayed their interest in history by indicating them prior to this date. At Pleshey, to the centre-bottom of the plan, a dark circular form represents the prehistoric earthworks used by the Romans, Saxons and Normans as a defensive position. At Barrington Hall to the left of centre, near the top, the details of ornamental gardens and avenues of trees are shown, an indication of the meticulous nature of the Survey.
