Chatham Convict Prison
Chatham Convict Prison was a large public-works penal establishment in St Mary's Island, Chatham, Kent, operating between 1856 and 1892. Designed by Major-General Sir Joshua Jebb, it was built to house male convicts employed on large civil and naval engineering works at Chatham Dockyard and the River Medway, and remained in operation until its closure in 1892.
