Mitford Castle stands as a Scheduled Ancient Monument in Morpeth, Northumberland, dating from the late 11th century when William Bertram originally constructed it in timber. His son Roger was granted permission to rebuild the fortification in stone in 1166, reflecting the castle's strategic importance in medieval Northumberland. Though reduced to ruins and destroyed by fire by 1323, this Grade I listed building continues to dominate the landscape west of Morpeth. Recently undergoing structural support works, Mitford Castle remains a visible reminder of Norman military architecture and feudal power structures in the English North.
