Canvey Island is a civil parishes in England and reclaimed island in the Thames estuary in England. It is separated from the mainland of south Essex by a network of creeks. Lying below sea level it is prone to flooding at exceptional tides, but has nevertheless been inhabited since the Roman invasion of Britain.
The island was mainly agricultural land until the 20th century when it became the fastest growing seaside resort in Britain between 1911-1951. The North Sea flood of 1953 devastated the island costing the lives of 58 islanders, and led to the temporary evacuation of the 13,000 residents.
