More than 25,000 artifacts, 100,000 printed items, 400,000 historic maps and photographs, and 9 million feet of motion-picture film. Founded in 1822, the Rhode Island Historical Society chronicles the past of its native state with an expansive collection, film screenings, special presentations, and other weekly events. In addition to these programs, the organization keeps local history alive at its three historic sites. Visitors can embark on guided or self-guided explorations of the 18th-century John Brown House Museum?a registered National Historic Landmark?as well as the library, which houses the society's collections. The Rhode Island Historical Society also oversees the Museum of Work and Culture, where exhibits recount the social, cultural, and economic history of northern Rhode Island through the 20th century.
