Arundel Castle - Construction

Construction

Work started on Arundel Castle in 1067 during the reign of William the Conqueror as a fortification for the mouth of the River Arun and a defensive position for the surrounding land against invasion from France. The 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 was a cousin of William's and had stayed in Normandy to keep the peace there whilst William was off 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.)

After Roger de Montgomery died, the castle reverted to the crown under Henry I. The King, in his will, left Arundel Castle and the attached land to his second wife Adeliza of Louvain. In 1138, three years after Henry's death, she married William d'Albini II (aka d'Aubigny, the first Earl, of the d'Aubigny family of Saint-Martin-d'Aubigny in Normandy). William was responsible for creating the stone shell on the motte, thus increasing the defence and status of the castle.
