Nice pics. I love old graveyards but unfortunately there's nothing local that comes close to the beauty of London's Magnificent Seven (Highgate rules!) or Europe's ancient burial grounds. Canada's too young, I guess. There are some beautiful cemeteries down in the city but, in general, they only go back about 150 years or so and are too well maintained to give one any creepy feelings. Still great places for a walk, though.
The oldest gravestone I've seen that is fully legible is in a rescued pioneer cemetery that's just under 3 miles from home. It goes back to 1812. There are some markers at another small pioneer memorial just over a mile away that date to the late 1700's but you'd have to wet the stones to have any chance of reading anything. (My brother visited Salem, Mass. during the summer, lucky dog. That goes back to the 1600's!)
I've been collecting pictures of cemeteries, ruins, abandoned vehicles, haunted houses, megaliths, creepy nature, etc. for several years now and have over 2300 at the moment. If you have no objection, I'll add some of yours to my Nunhead folder.
I really want to do a diorama/vignette of an abandoned and overgrown section of a cemetery, preferably with a small mausoleum (something like Uncle Mike's Crypt of Cthulhu). Some day...
