of the Logan County circuit court. As a result, very little is known of Lincoln's specific legal cases in Logan County during the Mount Pulaski interval. After 1855 Mount Pulaski only served as the county seat until 1853, when it moved to Lincoln, so the courthouse only served in its intended capacity for five years. After 1853, the building served as a school, the Mount Pulaski city hall and jail, and the local post office. Illinois Governor Henry Horner launched a statewide search in the 1930s for surviving public buildings with which Lincoln had been familiar. Mount Pulaski gave the old brick courthouse building to the state of Illinois in 1936, and the state extensively restored it in 1936–1939 to resemble its function as the county courthouse. The courthouse was added to the National Register of Historic Places on August 3, 1978, qualifying both because of its place in local history and because of its historically significant architecture. According to a member of the Logan County planning commission at the time, the building "ranks among the finest and best-preserved pre-1850 buildings in the state."
