The Michigan Paper Company Mill Historic District, also known as the Plainwell Paper Company Complex, is a complex of industrial buildings located at 200 Allegan Street in Plainwell, Michigan. It was added to the National Register of Historic Places in 2011. History The first paper mill established in the southwest Michigan region was the Kalamazoo Paper Company, which was constructed on Portage Creek in Kalamazoo in 1867 by Benjamin F. Lyon, an experienced paper mill operator from Fitchburg, Massachusetts. Although this business was ultimately unsuccessful, Lyon persevered, and in 1872 formed a partnership with Hale W. Page, another Fitchburg paper mill operator. The two constructed another mill near downtown Plainwell, which had just recently been connected to the Michigan Central Railroad. In 1887, Page formed another partnership with local Plainwell businessmen, and founded the Michigan Paper Company. They constructed a paper mill on this site, next to Lyon's 1872 mill. The Michigan Paper Company was an immediate success, and in 1890 they purchased the B. F. Lyon & Co. Mill, which had ceased production only three years earlier. In 1906, the company massively expanded their factory complex, engaging architect Daniel J. Albertson to design a complete new mill. Albertson designed eight new buildings for the site, allowing the paper making process to operate much like the assembly line in an auto factory. The company continued to thrive, and in 1910 expanded again, constructing a new office building and another set of buildings which mirrored the 1906 expansion, giving the company two separate production lines. In 1927, Michigan Paper purchased a paper coating company in Kalamazoo, and in 1940 moved the coating machinery to the Plainwell plant. In 1954, W.C. Hamilton and Sons purchased the outstanding stocks, and the business became a wholly owned subsidiary of the national corporation of Hamilton Paper. Michigan Paper began to compete as a niche paper manufacturer, and at the same time demolished its office building and constructed a new one. In 1961, Weyerhaeuser purchased the company, and in 1970 it was sold to Philip Morris, who renamed it the Plainwell Paper Company and continued to remodel the complex. The company was sold multiple times in the 1980s, and was eventually included as an EPA superfund site. The mill was eventually decommissioned in 2000, and in 2006 sold to the city of Plainwell. Preliminary environmental cleanup took place in 2007. In 2010, the City of Plainwell
