Me and man gone wrong were in the area and we decided to go have a look at this fort. I had come across it online and soon found it on maps. I do like these gun batteries so we were quite pleased to see it was still in good condition. Built and finished in 1893 the fort consisted of six guns which could have the rounds lifted to them through lifts in the underground tunnels. Used to defend the Thames alongside Coalhouse fort. It consisted of four six pdr guns and two ten pdrs in the middle. The fort was decommissioned in 1913 and sold to a farmer who used it as an air raid shelter during world war two. The fort has casements and barrack rooms. And some other buildings opposite the gun areas.
