Local signage states :-
"The basement is a low vaulted cellar with a well in the center of the room (Now blocked up, capped with square tiles) and contains four lockable side rooms.
The room in the east wall contains two aumbries (wall cupboards) for extra storage.
Due to its location, close to the original stone Great Hall outside, it is most likely that this was the buttery cellar for storing ale and wine.
The walls here are the thickest in the castle, at 4.25 metres.
This room is said to have been a prison during the Civil War"
