G. Sargent & Sons machinery works, the Abbot Worsted Company mill and local granite quarries. It preserves industrial buildings, quarry sites, institutional buildings and housing for owners and mill workers. The district retains integrity of design, feeling, association, materials and workmanship.","narrative":"Graniteville is a mill and quarry village in Westford, Massachusetts, set along Stony Brook and its millpond. Until 1847 it was a sparsely settled farming and quarrying area called Stone Quarry. The Stony Brook Railroad, Benjamin Palmer's granite quarry and, in 1858, Charles G. Sargent's stone textile-machinery mill turned it into an industrial community. The district holds 169 contributing resources, including two granite mills with mansard-roofed towers, the Sargent machine shop of 1877, a foundry complex, and three historic quarry sites on Snake Meadow Hill. Housing ranges from high-style Victorian Eclectic mansions built by Sargent, Fletcher and Reed to modest duplexes for mill workers. A Gothic Revival Methodist church of 1870, funded largely by Sargent, and the Stick-style Sargent Elementary School of 1885 anchor the neighborhood. Streetcar service, immigration and later Catholic institutions added to the village's development.","period_of_significance":null,"architect_builder":"Shepard S.
