These historical walls have value as heritage objects that deserve protection. The first step to protection is to know where they are. We could also then track their loses due to development or theft.</div><div><br></div><div>Also, what do people think about mapping cellar holes? I searched for tags that would be suitable for mapping cellar holes but didn't find any. I love in an historic district and mapping the cellar holes adds to the historical context of the district.
