Arundel Castle has been the principal seat of the Dukes of Norfolk and their ancestors for more than 850 years. Built in the 11th century by Roger de Montgomery, Earl of Arundel, the castle was seized by the crown in 1102. King Henry II, who added on to the castle, in 1155 confirmed William d'Aubigny as Earl of Arundel, with the honour and the castle of Arundel. Arundel Castle is still to this day the home of The Duke and Duchess of Norfolk and their children. The Fitzalan Chapel, founded in 1390 by the 4th Earl of Arundel, is located on the western grounds outside the castle, and has been the burial place of the most recent Dukes of Norfolk.
