Sussex is an area of South East England that was historically a kingdom and, later, a county. The current ceremonial counties of East Sussex and West Sussex cover approximately the same area. The two ceremonial counties border Surrey to the north, Kent to the north-east, the English Channel to the south, and Hampshire to the west. Sussex contains the city of Brighton and Hove and its wider city region, part of the South Downs National Park and the national landscape of the High Weald, and Chichester Harbour. Its coastline is 137 miles (220 km) long.
