The 16-room manor was completed in 1855 and was first occupied by governor Joel Aldrich Matteson, who held the official grand opening on January 10, 1856. It is the oldest historic residence in the state of Illinois and one of the three oldest continuously-occupied governor's mansions in the United States. In 2011, a multimillion dollar renovation was planned because the last repairs to the mansion were in 1971.^[3]
