The mill privilege was first developed in 1732 and contributed to the growth of Centre Village. The 1908 brick factory is described as an excellent example of the large-scale brick buildings of the period.","narrative":"Central Mills is a brick factory complex at the edge of Southbridge's central business district, along North, Foster and Central Streets. The main block, rebuilt in 1908 in a low Romanesque Industrial style, has a two-story facade tower with Roman arches and arched brick corbelling. A small one-story office in matching style sits in front, a rebuilt section from 1837 is attached at the rear, and a ca. 1915 brick storehouse stands across North Street. The site was a water privilege where Moses Marcy built the town's first sawmill in 1732. The Central Manufacturing Company, formed in 1837, built the first mill here. The 1908 rebuilding gave it 400 looms and electric power, producing 6,500,000 yards of cotton sheeting a year. It remained an important local employer well into the 20th century. The district was listed for its association with the town's industrial economy and as a strong example of large brick factory architecture, and it retains its setting, materials and design.","period_of_significance":"1837-ca. 1915","architect_builder":null,"architectural_style":"Romanesque Industrial","criteria":["A","C"],"status_note":"Present use is industrial and commercial; general condition is good.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:01.449679-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/53/7935/63793553/content/electronic-records/rg-079/NPS_MA/89000595.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/89000595/11b1e83b86-800.webp","url_1600":"https://nationalhistoricalregister.com/media/89000595/11b1e83b86-1600.webp","licence":"Public domain","author":"Marcbela (Marc N.
