John Paston, with some justification, claimed to be his heir; this put him in direct conflict with various major players of the time, such as the Duke of Norfolk and Sir William Yelverton.
As a result, the castle was besieged in August 1469 by the Duke – in pursuit of his own claim of ownership – and defended by John Paston junior and approximately 30 men.
The two-month defence was unsuccessful, resulting in the death of one of the Paston's longest-serving servants by a crossbow wound, and the loss of the castle to the Duke.
David Collyer removed a newell staircase with 122 stone steps from the tower and incorporated in into his house at Wroxham.
The museum also displays bicycles, horse-drawn vehicles, pedal cars, agriculture equipment and transportation items.
