You never know what you'll find in your own neighborhood!

Saturday afternoon I was out for a walk and passed an overgrown lot.  Previously I had only glimpses of an outcrop with a small stone building built against it, and an old chicken coop.  The landowner has recently cleared out some of the weeds to make a driveway, revealing this scene:

The small stone building is to the left, and what looks like a niche decorated with quartz is to the right. Or maybe it's a structure with some farming function.  Across the street is this structure, incorporated into the landscaping.

And finally, a few blocks away in another vacant, thorn-choked lot, another outcrop with a ruined stone house, and this:

This outcrop also has a stone row with a manitou.

All of these are less than 0.25 mile from each other, and in a neighborhood 1 mile from the Providence city limits!
