Lynnfield was first settled in 1638 and was made a district in 1782. It was later officially incorporated in 1842. Historically, Lynnfield functioned as two separate villages connected by one governing body: in Lynnfield Center resided a mostly agricultural population, while South Lynnfield was a crossroad situated amongst neighboring larger towns. During this time, the town had two inns, a quarry, a small carbonated beverage bottler, and various eating institutions. Route 1 (or "the Turnpike") was built through South Lynnfield, which brought many people to the small town. Lynnfield has since become a modern, chiefly residential suburb of Boston.
