US President and Indiana Territorial Governor William Henry Harrison's Mansion "Grouseland," in Vincennes

Built in 1804 and home to former United States president, William Henry Harrison, this Federal style building was given its unusual nick-name thanks to the local abundance of grouse, a plump game-bird. Grouseland was designated a National Historic Landmark in 1960 and listed in the National Register of Historic Places in 1966. It is maintained by the Grouseland Foundation.
