 There is the possibility that Bury Mount does not follow the standard form.In 1392 it was described as a mound tower within a moat, which suggests that it would have had a stone tower as a wooden tower is unlikely at that date.Shortly before 1824, possibly whilst they were excavating away the south-west section of the mount to construct a cottage, a "subterraeneous arched passage fifteen yards in length" was found.
