The Seven Sisters is a series of chalk cliffs by the English Channel with a break in the cliffs created by erosion known as the Birling Gap.
The chalk cliffs form part of the South Downs in East Sussex, between the towns of Seaford and Eastbourne in southern England. They are situated within the Seven Sisters Country Park which is bounded by the coast, the river Cuckmere and the A259 road.
Occasionally, the Seven Sisters are used in films and television programmes such as Robin Hood: Prince of Thieves and Atonement. They are a stand-in for the more famous White Cliffs of Dover because they are relatively free of modern development and are allowed to erode naturally keeping them their very bright white colour. The White Cliffs of Dover on the other hand are protected due to the important port they surround and are increasingly covered in vegetation and are greening as a result.
