Chesil Beach , sometimes called Chesil Bank, in Dorset, southern England is one of three major shingle structures in Britain. Its name is derived from the Old English ceosel or cisel, meaning "gravel" or "shingle".
The beach is often identified as a tombolo, although research into the geomorphology of the area has revealed that it is in fact a barrier beach which has "rolled" landwards, joining the mainland with the Isle of Portland and giving the appearance of a tombolo. The shingle beach is 29 kilometres long, 200 metres wide and 15 metres high. The beach and The Fleet, a shallow tidal lagoon, are part of the Jurassic Coast and a UNESCO World Heritage Site.
