Winchester was first settled by Charlestown citizens who were granted land in the northern ranges of their town in the 1630's in districts originally designated Waterfield and Rockfield. Much of this land formed part of Woburn after that town was incorporated in 1642. Other Charlestown lands now part of present-day Winchester were annexed to Medford in 1753 and to West Cambridge (later Arlington) just several years before Winchester's own incorporation. Early settlement was concentrated along Cambridge Street (the Cambridge-Woburn road) with some scattered upland farms to the west, and along Richardson's Row (Washington Street).
