Thank you for this interesting and informative post. Your photos show the damage that is being wrought through time and neglect. One of the things that keep British mnuments from falling into disrepair and devastation are organisations such as English heritage, National Trust and so on. But most of all it depends on insdividuals who have driven an idea to renovate something that is decrepid and gather volunteers in their wake. I don't know if you have anything like this, but it's a place to start. It would serve history.
