The Gatehouse website record for Dewy Hill

In the civil parish of Bolingbroke. In the historic county of Lincolnshire (Modern Authority of Lincolnshire, 1974 county of Lincolnshire).

Ringwork. Survives as roughly rectangular cropmark with slightly large area in southeast corner on top of hill overlooking Bolingbroke castle. Possibly built on site of an early medieval fortification and/or settlement. The site is now ploughed flat.
Although not well documented until the 13th century, it has always been assumed that there had been a castle at Bolingbroke since the 12th century. Excataions on the castle site therefore prompted the thought that the site of the castle had been moved. There is an earthwork, 120 yards long and 80 yards broad, on Dewy Hill. 500 yards north of the present castle. In October 1965 five days were spent on this site trial trenching. Evidence of an earthwork was found, and traces of occupation (bones, sherds, a buckle and hone) of 11th to 12th century date were found, although the earthworks themselves might be of earlier origin. The occupation is of the right date, but the evidence is still a little slender to speak of a castle. (Lincolnshire HER referencing 1965 article in East Midlands Archaeological Bulletin)
