Illinois Department of Natural Resources
The mission of the Division of Historic Sites of the Illinois Department of Natural Resources is to collect, preserve, interpret and communicate the diverse heritage of Illinois. The David Davis Mansion is one of fifty-eight historic properties which the division was created to preserve and interpret.
A Board of Trustees, appointed by the Governor of Illinois and confirmed by the Senate, manages the IDNR; the Board appoints the Director of the Agency, who oversees day-to-day operations. Within the IDNR, the Historic Sites Division interprets and maintains all historic properties managed by the state, including the David Davis Mansion. The mansion's director, known as the Site Superintendent, reports to the Superintendent of the Historic Sites Division, who reports, in turn, to the IDNR Director.
