Catherine went to live at The More castle late in 1531. After that she was successively moved to the Royal Palace of Hatfield, (May to September, 1532), Elsyng Palace, Enfield (September 1532 to February 1533), Ampthill Castle (February to July, 1533) and Buckden Towers (July 1533 to May 1534). She was then finally transferred to Kimbolton Castle where, she confined herself to one room (which she left only to attend Mass), dressed only in the hair shirt of the Order of St. Francis, and fasted continuously. While she was permitted to receive occasional visitors, she was forbidden to see her daughter Mary.
