Marlborough Castle

Marlborough Castle stands on a prehistoric mound in the market town of Marlborough, Wiltshire. The earthwork, known as Marlborough Mound, was built around 2400 BC and later became the motte of a Norman castle. William the Conqueror ordered a wooden motte-and-bailey castle to be built there in 1067. The site became a royal residence, hosting Henry I in 1110 and later John, who visited 51 times during his reign. The castle’s stone buildings were strengthened around 1175, and it served as an administrative centre under John. The castle played a key role in royal politics during the 12th and 13th centuries. Henry III spent £2,000 on its buildings between 1227 and 1272, including apartments and a chapel. Eleanor of Brittany, a rival claimant to the throne, was held there as a prisoner. After Henry III’s death, the castle became a dower house for his widow, Queen Eleanor. Later, it passed to Edward I’s daughter and then to his second wife, Queen Marguerite. Today, the tree-covered mound survives within the grounds of Marlborough College. Excavations have revealed parts of the keep and curtain wall. Neolithic artefacts and a Roman coin have also been found nearby. The mound remains a Scheduled Monument, offering a glimpse of the site’s layered history. Though the castle itself is long gone, the mound stands as a silent witness to centuries of royal power and intrigue.
