The Jubilee College State Historic Site preserves the remnants of Jubilee College, which was founded in 1839 by Philander Chase, the first Episcopal Bishop of Illinois. The school included a theological seminary, a college, a classical preparatory school for boys, a seminary for girls, and some small farming operations. Now, visitors can tour the school, which has been partially restored to its 19th century state. In particular, visitors are offered a guided tour of the recreated chapel/schoolroom/dormitory wing and the recreated library and schoolmaster's office.

The site is part of the greater Illinois Historic Preservation Agency (IHPA) website, and so only offers minimal visitor information regarding Jubilee College, but does offer links to the greater resources of the IHPA and other historic sites in Illinois, including Abraham Lincoln's presidential library.
