Sheerness defences is a military fortification complex located at Sheerness in Kent, dating from the seventeenth century onwards. The defences were constructed to protect the naval dockyard and anchorage at this strategically important location on the Isle of Sheppey, reflecting the significant investment in coastal defence during the period following the establishment of the Royal Dockyard at Sheerness in 1665. The fortifications comprise various earthwork and masonry structures built at different phases, including batteries and gun emplacements designed to counter threats from sea-based attack. These defences represent an important example of the evolution of English military architecture in response to naval power and the protection of valuable maritime infrastructure.
