Market town in West Sussex, southern England, on the River Arun; population (2001) 4,200. Tourism is an important summer industry. Its Norman castle, much restored, is the seat of the Duke of Norfolk and Earl of Arundel, Earl Marshal of England.
Features Arundel Castle, the seat of the Fitzalan-Howard family, Dukes of Norfolk, was built in 1067 by the cousin of William (I) the Conqueror, Roger Montgomery, to defend the Arun valley; its large stone keep dates from the 12th century. During the English Civil War the castle was besieged from 1643 to 1644 and almost ruined by Oliver Cromwell's Parliamentary troops. It was rebuilt in the 18th century and much restoration work was carried out in 1890.
The church of St Nicholas, dating from 1380, has a pre-Reformation pulpit and 14th-century wall paintings. The 14th-century Fitzalan Chapel stands behind the altar, separated from the rest of the church by an iron grille and glass screen. Catholic services are held in the chapel, which belongs to the estate of the Duke of Norfolk and can be entered from the castle. It was restored by the 15th Duke of Norfolk in 1886. The Roman Catholic church of St Philip Neri (13th earl of Arundel and one of 40 martyrs), built by the 15th Duke in 1873, became a cathedral in 1965. Its name was changed to Our Lady and St Philip Howard following the saint's canonization in 1970, and the transfer of his remains to a new shrine in the cathedral in 1971.
A reedbed on the Arun, part of a Wildfowl and Wetlands Trust reserve at Arundel, is a Site of Special Scientific Interest, supporting a population of warblers.
