I was saying "Ugh" out loud even before I saw the photo of that poor rat, because that derelict mill is in a right state! But some these photos are beautiful. I love the St John the Evangelist church, and the Unnamed House looks lovely until you see the boarded up windows and the creepy wide-open "grinning mouth" doorway.
I'd love to explore that church. But I don't think £75k would be "cheap" - it would probably be a listed building and would cost a fortune to renovate or convert into anything.
