Castle Point

Castle Point is a local government district in Essex made up of Canvey Island and the mainland towns of Benfleet, Thundersley and Hadleigh. The district sits on the Thames Estuary and includes low-lying reclaimed land with sea defences on Canvey Island, Holehaven Creek and estuarine marshes. Remains of Hadleigh Castle stand on the ridge above the estuary, reflecting medieval coastal fortification. Canvey Island has a post-war industrial history and a patchwork of sea walls and groynes; a section of the island, Canvey Wick, is a brownfield reserve that supports rare invertebrates and plants.

Settlement pattern mixes residential suburbs, local high streets and pockets of green space. The mainline rail at Benfleet links the district with central London and local centres, and ferries and creeks have shaped its shoreline use for fishing and small-scale boating. Local planning balances flood risk management, conservation of saltmarsh and reedbed, and pressures for housing and coastal frontage activity.
