Amidst the untamed beauty and savagery of the Illinois prairie sprang the elegance and grace of the Governor Duncan Mansion.
The Mansion was built by Joseph and Elizabeth Duncan in 1834. Joseph was the fifth elected governor of Illinois from 1834 to 1838. The building served as the official executive mansion and the family home during his tenure, during which the state capitol was in Vandalia.
Today, the home is restored to the time period of the Duncan’s and is open for tours. The home is owned and operated by the Rev. James Caldwell Chapter NSDAR.
We hope to see you at the Mansion soon!
