An area of agglomerated fields to the west of Bawtry. They are depicted on the 1894 OS map as enclosed strip fields which were derived from the consolidation of furlongs in medieval open fields. It is uncertain whether the open fields belonged to Bawtry or the deserted medieval village of Martin. During World War 2, Bircotes airfield was located on the site. There is very little trace of this left. It is first depicted as a disused aerodrome on the 1967 OS map. After the war, agricultural production intensified resulting in the removal of field boundaries. Legibility of the former landscape is invisible.
