Built in the 13th Century, possibly by William, Earl Marshall, the castle then formed a square with large corner towers.
Only half of the castle now remains – the most complete tower contains a fine circular chapel, with carved ornament.
The tower also has several original fireplaces and a vaulted basement.
In the Visitor Centre, 25 panels – produced by the Ferns Tapestry Project – depict the history of Ferns.
