Chartley Castle stands in ruins north of Stowe-by-Chartley in Staffordshire, midway between Stafford and Uttoxeter, as a motte-and-bailey fortress built around 1100 by an early Earl of Chester as a secure waypoint on aristocratic travels. Substantially rebuilt in 1220 by Ranulph de Blondeville, 4th Earl of Chester, the castle subsequently passed through the Ferrers and Devereux families over more than three centuries, gaining historical prominence when Mary, Queen of Scots was imprisoned on the estate in 1585. The earthworks and structural remains comprise an inner and outer bailey with 13th-century castle ruins and curtain walls, protected as a Scheduled Monument since 1925. This Midlands fortress witnessed pivotal moments in English history while exemplifying the architectural evolution from motte-and-bailey simplicity to more sophisticated stone fortifications.
