The 145-year-old South Dakota State Penitentiary in Sioux Falls is one of only a few active prison facilities in the country that was built in the 19th century. South Dakota lawmakers have been debating a new prison location that would replace the existing pen that was built in the early 1880s. Several states have men’s state correctional facilities older than South Dakota. Indiana State Prison was built in 1860, the Menard Correctional Center in Illinois opened in 1878, Wisconsin’s Waupun Correction Institution was finished in 1854 and the New Jersey State Prison was built in 1833.
