Exterior view of the main house at Grouseland, the home built by William Henry Harrison in Vincennes, Indiana, ca. 1920-1960. Harrison was selected by president John Adams to be the governor of the Indiana Territory, an office he held from 1800 until 1813. He moved to Vincennes, the territory's capital, in 1801, and built Grouseland in 1804. Now known as the William Henry Harrison Mansion and Museum, Grouseland has been restored and is a National Historic Landmark run by the Daughters of the American Revolution.
