The town's name changed to ''Burch'' (Old English ''burh'', "fort") after Abbot Kenulf constructed a defensive wall around the town. The name of the abbey's titular saint, ''Peter'', was prefixed to that name, giving rise to the modern name Peterborough. The town's name was recorded in the [[Domesday Book]] (1086) as ''Abbatia St Petri De Burg''. | The town's name changed to ''Burch'' (Old English ''burh'', "fort") after Abbot Kenulf constructed a defensive wall around the town.
