Who drew the boundary of Charlestown?

This answer was composed from the records listed beneath it, and from nothing else. Every statement carries the identifier of the record that supports it; every identifier was verified against the retrieved set before this page existed; and the records are named so the answer can be checked against them.

The archive records Charlestown as an official neighborhood of Boston, as bounded by the Boston Planning Department. urn:lemay:boston:entity:charlestown

That is the official layer — the boundary an authority drew — and on it Charlestown covers 872 acres. What people call this place, and where they say it reaches, are filed separately as attested claims. urn:lemay:boston:entity:charlestown
