During World War Two a four-storey observation tower was built on the original 1855 tower. The two quick-firing guns on the original roof were replaced with six-pounders. There is more than one way to get up to this roof, but some ways are slightly more precarious than others.
Remember the shell hoist within the main structure? The issue hatch is up on the roof, next to one of the gun positions.
The four-storey tower itself has one room on each level; the top two levels are observation posts. The tower is accessed via a concrete staircase with rusting metal handrails. It sits between the two gun positions, offering commanding views over the mouth of the river.
