The Sauk County Historical Society Museum, located in Baraboo, Wisconsin, is housed in the historic Jacob Van Orden House. Named after its builder, the house was constructed in 1903 in the Tudor Revival style. It replaced a home also built by Orden in 1879 which was sold and moved to another location in the city. The museum serves as the county's local history repository, containing thousands of artifacts and memorabilia. A research library is also in the house and contains photographs, documents, directories and books. The house, which remained in the Orden family, has been maintained in good condition and very little of it has changed; the woodwork, flooring, furniture and other features have been left largely intact. The historical society purchased the house in 1938 and opened it as a museum not long after. The house is listed on the National Register of Historical Places.
