Arundel Castle is home to the Fitzalan- Howard family, the Dukes of Norfolk. Next to the royal family they are the most aristocratic family in the country. They are the hereditary Earl Marshals of England. But their history is a chequered one. Despite the Reformation of the 16th century the Fitzalan-Howards have largely remained Roman Catholics. Until Catholic emancipation in the first part of the 19th century the Howard family suffered considerably because of their religion. The talk outlines the turbulent history of the Howard family from the late 15th century to the early 19th century. It includes the story of the martyred St Philip Howard to whom the Roman Catholic Cathedral in Arundel is dedicated. The talk also tells the story of Arundel Castle itself from medieval times to the present day. Until the end of the 16th century it was the home of the Fitzalan family alone. The Howards and the Fitzalans did not become united until that time. After that Arundel was not the family’s main home until the 18th and 19th centuries. It was Henry Fitzalan-Howard, the 15th Duke of Norfolk, who was responsible for designing the magnificent 19th century Neo-Gothic residence in which the family live today part of which is open to the public. The 15th Duke was also responsible for the building of the Roman Catholic Cathedral at Arundel in which there is a shrine to the martyred St Philip Howard. Arundel is unusual in that it has an ecclesiastical building divided between the Anglican and Roman–Catholic denominations. The nave of the medieval parish church of St Nicholas belongs to the Church of England and is used for Anglican worship. What used to be the chancel of the medieval parish church is still owned by the Fitzalan-Howard family and is still dedicated for Roman Catholic worship. It is physically separated from the nave. It is the burial ground of the Fitzalan-Howard family. Occasionally the chapel is opened so that ecumenical worship can take place with the Church of England congregation. The last time was in 2018 to mark the 100th anniversary of the end of the first World War.
