Bolingbroke Castle, at Bolingbroke (or Old Bolingbroke) in Lincolnshire was founded by Ranulf, Earl of Chester, during the early 13th century, and in 1311 passed to the House of Lancaster; its most famous owner was John of Gaunt. It was destroyed during the English Civil War, but has been partly restored.
Most of the castle is built of Spilsby greenstone, as is the nearby church. It was originally surrounded by a moat.
