It covers Main, Lincoln, Preston and Walnut Streets, Chestnut Hill Road and Burns Avenue, and is mostly residential.","why_significant":"The district holds a concentration of industrial worker housing from the period when Millville's economy and community boomed in the late 19th and early 20th centuries. It preserves a range of house types, from one-story duplexes to two-story tenements, along with early industrialists' houses, a rare Greek Revival commercial building, a church and industrial archeological sites. Together these show the social hierarchy of a mill village.","narrative":"Main Street Historic District occupies the north bank of the Blackstone River in Millville, Massachusetts, near the Rhode Island border. It takes in Main, Lincoln, Preston and Walnut Streets, Chestnut Hill Road and Burns Avenue, and contains 148 contributing resources. Most are houses, along with a few commercial buildings, a church, landscape features and the site of the U.S. Rubber Company factory. The district grew in stages. Early Federal and Greek Revival homes of mill owners faced the county road completed in 1831. After 1854, as growth shifted to the south side of the river, the hillside streets filled with worker housing: low one-story duplexes, larger two-story double houses and multi-unit tenements, many built by local property speculators. Later Queen Anne and Gothic Revival double houses appeared around 1890. A Greek Revival store at 5 Lincoln Street is a rare regional survivor. The district shows how housing, religion and commerce reflected a mill village's class structure.","period_of_significance":null,"architect_builder":null,"architectural_style":"Federal, Greek Revival, Gothic Revival, Italianate, Queen Anne, Colonial Revival, Bungalow/Craftsman","criteria":[],"status_note":"Mostly residential; surviving duplexes remain in housing use, though many have been enlarged and altered.
