In the eastern part of the parish are a number of prehistoric sites including a tumulus that still retains a few of the stones that formed its burial chamber.[4] Archaeological examination of the surface at the centre of the tumulus found three flints that showed signs of being worked and two small fragments of human skull.[8] In the Domesday Book, the manor is recorded as Cestitone, and its landowners as Odo, the Bishop of Bayeux, Henry de Ferrers and Urse d'Abetot.Later, in the Middle Ages, the manor's owners included Robert D'Oyly, the likely builder of Oxford Castle, and Thomas Chaucer, son of Geoffrey.The house is full of objects accumulated by the family over the years: rare tapestries, portraits, furniture, as well as personal belongings, some just lying around, such as walking sticks and wellington boots.
