Drakenage was a fortified manor house in the parish of Kingsbury, Warwickshire.  On the left is a plan of Drakenage from a map of 1832.  Presumably the existing modern house is sited below the old moat, where the medieval structure probably stood.
A little more detail can be seen to the right on a map from about 1900.  I am unaware of when the medieval structure was destroyed.  The small projection from the moat might have been a fish pond.
