Constructed between 1861 and 1874, the Coalhouse Fort was built to defend the Thames from a potential invasion by France, and was used as a battery in both world wars.
The Coalhouse Fort Project was set up in 1983 and the fort undergoing continuing refurbishment.
The Coalhouse Fort has a number of open days (closed in winter) and runs special events throughout the year. They also host paranormal nights!
ESSEX DAYS OUT TIP : Whilst we don’t have many castles in Essex, this is one of many fortifications along the Essex coast – there’s also Hadleigh Castle, Tilbury Fort, Jaywick Martello Tower, and the Harwich Redoubt.
