 Mansfield Hollow, located south of Mansfield Center, is one of the places where industry flourished, on the north bank of the Natchaug River, now a short way west of Mansfield Hollow State Park.This area's industrial history began in the 18th century, when Barzillai Swift acquired a water privilege, and established saw and grist mills.His sons George and Fearing continued the business, and also leased part of the privilege to Oliver Bingham.
