I have been looking for a while and I can't find anything on the net - I remember a good few years ago now watching an amazing History series simply called 'Castle'. It went from the very beginning of the existence in Britain of castles through to the end. It was amazing and has always stuck in my mind. I know that Neil Oliver presented it but I can't find any reference to it at all. Very hard to google because the word castle has so many associations. Am I going mad or can anyone else remember this? I'd like to get hold of it again.
