Historical Significance:

This was the home of the Territorial Governor of the Indiana Territory and ninth President of the United States William Henry Harrison. Also, it was the confrontational meeting place in 1810 and 1811 of Harrison and Shawnee leader Tecumseh.

 Note:  On the property grounds are two additional buildings. One is the Francis Vigo Chapter House. It was once a barracks located at the George Field Flight Training Base in Lawrence County, Illinois. The building was used for many years during the training of WWII pilots. The barracks was  moved from George Field Flight Training Base to it's present location in 1952. The Francis Vigo Chapter purchased the building in 1973 and since then have used it as their chapter house. This chapter house contains the history of the Francis Vigo Chapter in photos, books, records,  documents, and applications of members. It also contains many items left to the chapter by the descendants of William Henry Harrison such as sterling silver tea sets, carpets, paintings, antique mirrors, photos, and more.

The other building on the grounds is the Queen Anne Cottage. It was built in 1886 by the Vincennes Water Company to house the superintendant of the water company. The Vincennes Water Company were once owners of the William Henry Harrison Mansion, known as Grouseland, and the  current owner is Francis Vigo Chapter NSDAR. The chapter rents the two apartments that are in the building. This income helps to maintain the grounds of the mansion and for any repairs needed for the mansion, Francis Vigo Chapter House, or the Queen Anne Cottage.
