Governor Duncan Mansion

4 Duncan Place, Jacksonville, IL 62650

Historic Sites

This home served as the official executive mansion for the State of Illinois from 1834-1838. Today, the home is owned and operated by the Rev. James Caldwell Chapter NSDAR.

Governor Joseph Duncan, who served as governor of Illinois from 1834 to 1838, had this two-and one-half-story house constructed between 1833 and 1835. The home served as the official executive mansion for the state of Illinois and was used for State business during the term of Governor Joseph Duncan. This three-story, 17-room mansion was built in 1834.  It was placed on the National Register of Historic Places in 1971, and houses many of the original Duncan family furnishings. 

Tradition says that Lincoln visited the Duncan home, and it is quite possible that happened, given the fact that Lincoln lived in nearby New Salem and Springfield during the time both men were members of the Whig Party. Lincoln served his first two terms as a state representative while Duncan was governor. In addition, voting records show that Lincoln cast ballots for Duncan three times.

Duncan Mansion's winter hours are by appointment only.
