The Portage County Historical Society was founded with the intention to preserve, advance, and disseminate the history of Portage County, Wisconsin. To this end, "the Society currently operates four museums, maintains a large archives housed at the University of Wisconsin - Stevens Point's Archive Center, is developing its own research center, and maintains the Malcolm Rosholt Online Archives on this website to disseminate knowledge of the history of Portage County, Wisconsin." The museums are the Heritage Park, a historic park that gives visitors a glimpse of early frontier life, the Beth Israel Synagogue, which chronicles the history of Portage County's Jewish community, the Rising Star Mill, which gives visitors a tour of turn of the century industry, and Fire Station #2, which was scheduled to open in 2008 and contains a collection of vintage firefighting equipment.
The site offers historical and visitor information regarding all four museums, full archival access, a photo gallery section which has 10 photo galleries currently, three videos, and order information for society publications.
