Serpent Wall Located Off Scenic Road
There is a uniquely-styled Serpent Wall to be found in Hopkinton. When I led NEARA (New England Antiquities Research Association) members to the site measurements were taken and it was noted the wall was oriented (or ran along) Magnetic North. Below are some pictures, and a couple of nearby cairns. Note the erratic-looking style of the wall, which seemed to fortify a small knoll (as seen in picture 1 & 2).
