Arundel (/ˈærəndəl/ ARR-ən-dəl or locally /ˈɑːndəl/ AHN-dəl) is a market town and civil parish in the Arun District of the South Downs, West Sussex, England.

Arundel has a museum and comes second behind much larger Chichester in its number of listed buildings in West Sussex.

[9] Arundel civil parish occupies an area somewhat larger than its built-up clusters, with the old town towards the north and the new to the south, separated by a main road.

Arundel Castle was built by the Normans to protect that vulnerable fairly wooded plain to the north of the valley through the South Downs.

Arundel includes meadows to the south but is clustered north of the A27 road, which narrowly avoids the town centre by a short and congested single carriageway bypass.

[12] During 2018-19 there is a further period of consultation when views on a more detailed design for the four-mile (six-kilometre) dual carriageway will be sought.
