‘Alfred’s Castle, on the hill west of Ashdown, was called Ashberry Camp on a map of Shrivenham Hundred in 1532 referred to in Miller’s History of Ashbury, and it was given the alternative names of Alfred’s Castle and Ashbury Camp by Wise in 1738. There is no doubt that the original name was Ashbury Camp, and it is almost certainly the camp from which Ashbury was named, which was spelt Aescesburh in the Anglo-Saxon charters.‘
