Grain Fort was built during the 1860s on the Isle of Grain to protect the mouth of the river Medway. It was constructed with a crescent shaped keep, which formed the casemated barracks and entrance to the fort. A raised earth bank behind this formed the terreplein, which was mounted with Rifled Muzzle Loading guns in large gun pits. The fort was protected by a surrounding dry ditch that was flanked by four caponniers. Guns continued to be mounted on the fort throughout WW1 and WW2, and it finally left army hands in the 1950s. Unfortunately, during the 1960s the fort was demolished, leaving only the underground sections. The site has never been developed, and it is open land, the shape of the gun positions and a wall here and there are the only reminders of this once impressive fort. The tunnels, which led to the trucanted caponniers and main magazine, still remain and were accessible some years ago; however it appears they have now been filled in.
The remains of the fort are on open land and can be visited with some parts still recognisable, although the underground sections have now been buried.
The original plans give some idea to what is buried at this site
