There is an oak grove cemetery one town over from where I grew up that has resting places dating back to the the 1700's. Some of the older markers and monuments have the most amazing sculpture work!
Does that last shot have any filters? It almost looks like it has infrared qualities. That one was my favorite of the post!
I love checking out old cemeteries like the one you described
That last photo I did a different style of editing to give that effect
