Canvey Island

Canvey Island is a town, civil parish and reclaimed island in the Thames estuary, near Southend-on-Sea, in the Castle Point district, in the county of Essex, England. It has an area of and a population of 38,170. It is separated from the mainland of south Essex by a network of creeks. Lying only just above sea level, it is prone to flooding at exceptional tides and has been inhabited since the Roman conquest of Britain. The island was mainly agricultural land until the 20th century, when it became the fastest-growing seaside resort in Britain between 1911 and 1951. The North Sea flood of 1953 devastated the island, killing 58 islanders and leading to the temporary evacuation of the 13,000 residents. Canvey is consequently protected by modern sea defences comprising of concrete sea walls. Canvey Island is also notable for its relationship to the petrochemical industry. The island was the site of the first delivery in the world of liquefied natural gas by container ship and later became the subject of an influential assessment on the risks to a population living within the vicinity of petrochemical shipping and storage facilities. Excavations on Canvey have unearthed a collection of early man-made objects comprising axes from the Neolithic era, a bracelet dating from the Bronze Age, and Iron Age pottery. However, the remains of Roman structures and objects suggests the first settlement of Canvey occurred between AD 50 and 250. The remains point to a community existing with a farmstead, a garrison, a burial ground, and the operation of a large salt-making industry (revealed by the existence of several red hills). The discovery of a Roman road found to terminate across the creek in neighbouring Benfleet suggests a means may have existed to facilitate the salt's distribution to Chelmsford and Colchester, and the recovery of rich items of pottery and glassware of a variety only matched elsewhere by excavations of port facilities suggests the Romans may also have exploited Canvey's location in the Thames for shipping.
