This Queen Anne style house, completed in 1884, was the home of Henry A. Chapin's family until 1902. In 1932, when the City of Niles bought the property at auction for $300, the Chapin children stipulated that it be used only for civic purposes. Now serving as Niles City Hall, the house is built of local brick and terra-cotta tile, and its interior is ornamented with leaded glass windows and transoms, handcarved woodwork, and stenciled ceilings. In 1939 the Works Progress Administration joined the carriage house to another outbuilding, creating the Fort St. Joseph Museum structure. The museum holds over 10,000 items, including Fort St. Joseph and Potawatomi Indian artifacts, local memorabilia, and a collection of drawings by Chief Sitting Bull. Henry A. Chapin, who lived from 1813 to 1898, spent most of his early life in Ohio, married Ruby N. Nooney in 1836, and settled in Edwardsburg, Michigan. In 1846 Chapin and S.S. Griffin opened the first general store in Niles. With his son Charles, Henry A. later established an insurance and loan agency. Their firm had interests in nearby paper mills and electric companies and in real estate in Alabama, Illinois, and Michigan. The bulk of the family capital came from the discovery of iron ore in Michigan's Upper Peninsula. The Chapin Mine near Iron Mountain began operations in 1879, and Henry A., known as "Mr. H.A.," received up to $300,000 yearly in royalties from the mine. Owing to the Great Depression, the Chapin Mine closed in 1934 after fifty-five years of continuous production.
