NU 116324/Ruin/EH

Castle originally built as a motte and bailey in 1121 for Bishop Flambard and rebuilt in stone circa 1157 by Richard of Wolviston for Bishop Puiset. Additions were made in C13, including the great hall and south wall. The keep was remodelled between 1422-25. The last phase of construction was 1513-15 when rebuilding was carried out especially to the north wall for Bishop Ruthal. During the late C18 and early C19 one of the south turrets was encased in a gothic cottage. A possible outer enclosure encroaches into the field to the S . The castle lies within a possible Iron Age promontory fort , and there are various post-medieval artillery fortifications in the vicinity. Northam; Norrham
