Berkhamsted Castle Berkhamsted Castle is a Norman motte-and-bailey castle in Berkhamsted, Hertfordshire. The castle was built to obtain control of a key route between London and the Midlands during the Norman conquest of England in the 11th century. Robert of Mortain, William the Conqueror's half brother, was probably responsible for managing its construction, after which he became the castle's owner. The castle was surrounded by protective earthworks and a deer park for hunting. The castle became a new administrative centre of the former Anglo-Saxon settlement of Berkhamsted. Subsequent kings granted the castle to their chancellors. The castle was substantially expanded in the mid-12th century, probably by Thomas Becket.
Marlborough Castle Marlborough Castle, locally known and recorded in historical documents as "The Mount", was an 11th-century royal castle located in the civil parish of Marlborough, a market town in the English county of Wiltshire, on the Old Bath Road, the old main road from London to Bath (grid reference [ SU18376866] ). The barrow on which the fortification was built, perhaps the "barrow of Maerla" seems to be a prehistoric earthwork which formed the motte of the Norman Marlborough Castle. It survives as a tree-covered mound at the centre of Marlborough College.
