Tout Hill is a mid to late 11th century earthwork motte and bailey fortress, founded by Abbot Thorold of Peterborough. The large circular, flat-topped motte, was crowned by a timber tower and to the north-east is the site of the bailey. Raised on the north side of the Abbey, to prevent further attacks from the Danes, the mound now stands within the garden of the Deanery. The encasing motte ditch once survived to the north-west and excavation have found a north-eastern ditch which probably skirts the mound and presumably defended the bailey. 6 miles north is Northborough Manor House and 12 miles west is Fotheringhay Castle.
