PRN 34211 Unidentified earthworks reported in this field and crossed by a public right of way. The earthworks may relate to water management. {1} Medieval earthworks, many of buildings have been identified during the National Mapping Programme. It is the remains of a medieval and early post medieval village now abandoned but the date of its abandonment is not known. {2} This is almost certainly the medieval village of Twyford that is recorded in the Domesday Book with a minimum population of 16. It contained two estates the larger in the hands Countess Judith, the niece of William the Conqueror, of 5 and a half carucates while the smaller estate, of half a carucate, was in the hands of the Archbishop of York. Both estates were sokeland and were dependent on manors at North Witham. {3} The name Twyford comes from the Old English words for ‘two’ and ‘ford’ of ‘double ford’ and this refers to the village’s location at a crossing with two fords on the upper reaches of the river Witham. {4} It is recorded as a deserted medieval village in the records of the Medieval Village Research Group, where it is noted that there is little documentary evidence for the settlement other than Domesday. The settlement was taxed with North Witham and so does not appear in its own right in medieval taxation returns.{5} A Cambridge University aerial photograph taken in 1978 shows rectangular building platforms, a main street heading north towards Colsterworth, various earthwork enclosures and ridge and furrow earthworks on both sides of the river. {6} The place name Twyford was, by the nineteenth century, being used for the southernmost part of Colsterworth village. {7}{8}
