Arundel Castle is a restored and remodeled medieval castle in Arundel, West Sussex, England. It was established by Roger de Montgomery on Christmas Day 1068. Roger became the first to hold the earldom of Arundel by the graces of William the Conqueror. The castle was damaged in the English Civil War and then restored in the 18th and 19th centuries.From the 11th century, the castle has served as a home and has been in the ownership of the family of the Duke of Norfolk for over 400 years. It is the principal seat of the Norfolk family. It is a Grade I listed building.ConstructionThe original structure was a motte and double bailey castle. Roger de Montgomery was declared the first Earl of Arundel as the King granted him the property as part of a much larger package of hundreds of manors.Roger, who was a cousin of William, had stayed in Normandy to keep the peace there while William was away in England. He was rewarded for his loyalty with extensive lands in the Welsh Marches and across the country, together with one fifth of Sussex (Arundel Rape). (For other reasons, the generally accepted first creation of the title Earl of Arundel lies in the year 1138 with William d'Aubigny, confirmed in 1155.)
