Marlborough Castle

Marlborough Castle, locally known and recorded in historical documents as The Mound, was an 11th-century royal castle located in the civil parish of Marlborough, a market town in the English county of Wiltshire, on the Old Bath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 known as Marlborough Mound, within the site of Marlborough College. The Mound is on private ground and closed to the public except for occasional open days organised by the local council.
