View of Bolingbroke Castle, birthplace of Henry IV, with part of the village visible in the background.
Kelly's Directory of Lincolnshire 1919 states :-
"The castle stood at the southern extremity of the town, and some vestiges of it still remain, although constructed only of local sandstone:
it was, however, a formidable fortress until its capture during the Civil War; on Monday, October 9, 1643, it was attacked by the Parliamentary forces under the Earl of Manchester, and being surrendered after a few days resistance was then dismantled and left to decay :
the gatehouse, the last crumbling remnant, is said to have fallen down in May, 1815.
The Royal army, when advancing to its relief, suffered a severe reverse at Winceby, near here, October 11, 1643"
