Ancient Graves

I noticed these graves last night when on a trip into Lincoln to go to the cinema. They are near an old Quaker church, though they are actually associated with a different church, St Martin's, which is no longer there. In a weird kind of full-circle turn of events St Martin's was formerly St Mary Crackpool. Judging by the debris I managed not to show in this pic, that would probably be an apt name to revive!
