That's nice, Dave.
I have been fascinated by these places ever since I was shown, by a teacher, a footpath paved with the unmarked (or worn down) gravesones of paupers leading down a twitten (what a fantastic word that is!) close to the churchyard back home in Sussex. My wife and I recently spent a few hours in the big graveyard here in Lancaster, photographing the sights. Perhaps I'll post some of the images elsewhere later.
