It began in 1885 as the Cleghorn Mill and was expanded by the Parkhill Manufacturing Company.","why_significant":"The complex is argued to represent Fitchburg's cotton textile industry and its period of greatest growth and expansion from 1885 to 1915. Parkhill's gingham production marked a new era of prosperity for the city and spurred the growth of the surrounding Cleghorn neighborhood. The buildings also illustrate utilitarian industrial architecture and the move toward steel-framed mill construction.","narrative":"Parkhill Mill is a U-shaped complex of brick mill buildings beside the Nashua River in Fitchburg, Massachusetts. Construction began in 1885 when Andrew Cleghorn built a four-story weaving mill and a brick power plant with a 100-foot chimney. John Parkhill bought the property in 1889, and the Parkhill Manufacturing Company added steel-framed four-story buildings in 1909 and 1915. A railroad bridge from about 1930 crosses the river beside the site. The buildings are plain and functional, with granite sills, segmented brick arches and very large windows meant to bring in daylight. The complex handled the whole cotton process, from raw bales to finished ginghams and chambrays. Parkhill's success marked a new period of prosperity for Fitchburg and helped create the surrounding Cleghorn neighborhood, where workers, many of them French Canadian, settled near the mills. Two outbuildings were demolished in 2001, but the remaining buildings retain the character of the years from 1885 to 1915.","period_of_significance":null,"architect_builder":null,"architectural_style":"Other: Utilitarian Industrial / Light Industrial","criteria":[],"status_note":"Current functions are listed as education, business/office space and vacant (not in use).
