I have always fancied this place, it's a place that quite interested me. And given that the whole fort with its bastions is the biggest in the country, so whilst me and man gone wrong were in Kent we went for a look. The outside is quite impressive alone, but inside I found the work in how it was built fascinating. The brickwork is very impressive and all built underground too. Sadly when we were in there, a gang of kids were in there playing manhunt.to be fair they were a decent bunch just having fun. This place has been covered many times so won't go deep into history. Just the central fort and central and detached bastion was made as one of the most advanced gun emplacements. The remains of the drawbridges were impressive and if ever Napoleon invaded and breached the outer defences the bridges would be drawn in. I noticed inside there was big slopes and at the bottom of the slopes was a small bridge, I would think this was the last defence if they ever actually got in and the would have to cross the small pit and the soldiers would have there last stand. It never happened though.
