This manuscript map of Boston Harbor created by Jeremy Belknap in 1775, presents a large perspective of Eastern Massachusetts and the islands in the Massachusetts Bay. This map depicts the harbor islands, coastal towns from Lynn to Hingham, and roads to inland towns such as Providence, Taunton, Watertown, Worcester, Concord, and Andover. Belknap's map indicates the major settlements and developments in Boston, Roxbury, and Charlestown, as well as minor settlements and developments in Medford, Malden, Cambridge, Watertown, and at Point Shirley in Winthrop. A piece of the map is missing along the fold line.
