 It is the easternmost point of Bracklesham Bay and the westernmost point of the Sussex Coast.Although the place name "Selsey" has existed since Saxon times, and is derived from the Old English meaning "Seal's Island", there is no evidence to suggest that the place name "Selsey Bill" is particularly old.A 1698 survey of the area included in a report for the Royal Navy, by Dummer and Wiltshaw mentioned Selsey Island but not Selsey Bill.
