A small but complex fortified manor of many periods. Destroyed 1828. The excavations of 1963-69, lead by Gary Dowdell, on the site of the castle revealed six phases of occupation ranging from the Romano-British to C17-C18. Four were medieval (phases 2-5) from which were deduced two main periods of building: I, an earthwork (probably a ringwork) of C12 to which a stone keep was added (phases 2-3), and II, a fortified manor-house of C13 and early C14. Fragments of painted wallplaster of unknown date were also recovered. (Derived from Coflein)

Gatehouse Comments

Rob Prince, who took part in the excavations, kindly informs Gatehouse that 'part of a wall and one gate remain at the rear of Sully church, and form part of the church's perimeter wall (north eastern corner)'.
