Chesil Cove is a curved steep bank forming the south-east end of Chesil Beach in Dorset, England. It is thus part of one of three large shingle structures in Britain, extending from West Bay to the Isle of Portland (Portland Bill), the latter acting more firmly as a great barrier (groyne) which stops tidal action from washing the beach away and leads to the high depositions by wind and tide action forming the grand curved bank of this "cove". The "cove", bill and much of Chesil Beach give shelter from the prevailing winds and waves for much of Weymouth Bay, the town of Weymouth and the village of Chiswell. It forms part of the Jurassic Coast. Flooding defences The adjoining village of Chiswell was established predominately as a fishing community. Despite its vulnerability to sea storms and flooding, Chiswell developed into a thriving community. One of the best-documented incidents of flooding occurred in the Great Storm of 1824. The storm saw the death of thirty residents, the destruction of eighty houses, and the damage of many others. The construction of a sea wall finally commenced in 1958, and work on this scheme continued until 1965. The wall extended from the far end of Chesil Cove, at West Weares, to the location of the village's Cove House Inn. A promenade was laid-out on top of the wall, and this became a popular attraction. Despite the sea wall proving a worthy defence, incidents of widespread flooding continue. During December 1978 and February 1979, two major storms caused further devastation to Chiswell. Accordingly, further defence were installated during the 1980s. During January–February 2014, violent storms across the south-west of England caused more flooding in the village. Recreation Diving Chesil Cove is a popular site for scuba divers. It has become one of the best known shore dives in the UK. The cove is a reasonably shallow shore dive, and has an interesting selection of south coast marine life, as well as an abundance of flora and fauna. Although there have been many shipwrecks in the cove, few significant divable remains exist close to the beach due to its exposure to strong waves. Fishing Through fishing, the beach provided the main occupation for the villagers of Chiswell and the rest of the islanders. The beach is still used by sea anglers and the British record for shore-captured shore rockling was set there in 1992.
