The Seven Sisters are a series of chalk cliffs by the English Channel. They form part of the South Downs in East Sussex, between the towns of Seaford and Eastbourne in southern England. They are within the Seven Sisters Country Park. They are the remnants of dry valleys in the chalk South Downs, which are gradually being eroded by the sea.
The Seven Sisters cliffs are occasionally used in filmmaking and television production as a stand-in for the more famous white cliffs of Dover, since they are relatively free of anachronistic modern development. They are also featured at the beginning of the film Robin Hood: Prince of Thieves, and at the end of the film Atonement where Robbie and Cecilia always wanted to live.
From west to east, the sequence starts just east of Cuckmere Haven. The cliff peaks and the dips between them are individually named. Listed below, the peaks are in italics. There are seven hills, with an eighth one being created by the erosion of the sea.
The South Downs Way runs along the edge of the cliffs, taking a very undulating course.
Many landmarks around the area are named after the cliffs, including the Seven Sisters Sheep Centre.
In summer 2009, a landscape photograph of the cliffs was chosen as an official desktop wallpaper and included with the Microsoft operating system Windows 7 as part of the "United Kingdom" localised theme, unavailable (by default) to other locale systems. The image is very similar to and from the same viewpoint as the image displayed above.
