prominent headland on the English Channel coast in the administrative county of East Sussex, historic county of Sussex, England, in the borough of Eastbourne. Its chalk cliffs, more than 500 ft (150 m) high, represent the seaward extension of the South Downs. The cliffs face southward and are therefore subjected to severe gales from the southwest. Erosion is concentrated along joint planes and tends to produce isolated stacks. There were once seven of these, the Seven Charleses; the last fell in 1875.
