Ghostly bread oven figure

On the 22nd July 2017 at 8.45am on a clear sunny day a ghostly figure was seen. One of the workers was leaning down to light the fire in the bread oven when he suddenly felt a presence next to him. At first he thought it was another member of staff, but when he turned around he saw a man with dark hair, dressed in Norman clothing in a smock type costume. This ghostly figure was standing staring at him with his chin over the top of his shoulder. When the startled member of staff jumped back the figure just disappeared. Another member of staff was working nearby and heard the commotion and looked over and saw a grey mist where the figure had been. The same figure has been seen before, over the years, in different parts of the castle.
