Baconsthorpe Castle, historically known as Baconsthorpe Hall, is a ruined, fortified manor house near the village of Baconsthorpe, Norfolk, England. It was established in the 15th century on the site of a former manor hall, probably by John Heydon I and his father, William. John was an ambitious lawyer with many enemies, and built a tall, fortified house, but his descendants became wealthy sheep farmers and, less worried about any attack, developed the property into a more elegant, courtyard house, complete with a nearby deer park.
