Mill Mount (Castle Mount - Class D Earthwork) Southwest of Redisham village is a small circular mount 9 ft high, with a slight depression in the middle of its summit. It is surrounded by a fosse with a counterscarp now measuring 4 ft at its highest point, and a breadth of 10 ft at its broadest part; but both height and width have been badly trodden by cattle (VCH). "On Mill Mount; a castle mound, presumably later used for the base of a windmill" (Pevsner). Mill Mount was bulldozed flat three years ago leaving no trace. It stood on level ground which was under crop at the time of investigation. No further information to verify classification as a "castle mound" (Field Investigators Comments-F1 NKB 09-JUL-73).

The location, isolated and a kilometre from the parish church, seems very unlikely as a castle, although King and Pevsner seem to have had no doubt. It is now unlikely that any evidence has survived (Was gaining this awkward corner of a field worth destroying this site?). Robert Liddiard has shown that, in East Anglia, castle can be pushed out from village centres onto poorer agricultural land - this is clearly not the situation here. The position on the parish boundary might be coincidental but may suggest a pre-historic origin. Despite King I consider this a questionable site.
