Kirkoswald Castle, Kirkoswald in the Eden Valley, Cumbria.
A fortification has stood on this site since the 12th century. It was destroyed by Robert the Bruce in 1314, and a year later came into the possession of Ranolfe de Dacre by abducting and marrying the heiress of the castle! His descendant, Thomas Dacre made extensive improvements but in the 1569 rebellion, the Dacres lost possession and the owners of Naworth Castle plundered the site in the 17th century.
A footpath passes close to the castle, but the castle is on private land.
