Grouseland, the William Henry Harrison Mansion and Museum, is a National Historic Landmark important for its architecture and role in history. Grouseland is a large, two-story red brick home built for William Henry Harrison in Vincennes, Indiana, during his term as Governor of the Indiana Territory. The mansion was completed in 1804 and reportedly dubbed Grouseland by William Henry Harrison due to the abundance of grouse in the area. 
Grouseland was designed by the architect William Lindsay and constructed at great personal expense to Governor Harrison. The project was daunting: at the dawn of the 19th century, the territory had no established roads, and Vincennes itself had a population estimated at only 700. Nevertheless, Grouseland was built from local materials by skilled labor, and decorated in grand style with items imported from Europe. It is surmised by at least one biographer that Harrison's motives in constructing such a Xanadu in the wilderness included establishing the respect due to him as governor, despite his relative youth at the time. Grouseland served Harrison's position and marked his place in American aristocracy—William Henry was the youngest son of Benjamin Harrison, V, a signer of The Declaration of Independence. 
During Harrison's governorship of the Indiana Territory, Grouseland was the focal point of the social and official life of the territory. As the capital of the Northwest Territory, more territory was governed from Vincennes than any city outside Washington, D.C.  Grouseland was home to Harrison until 1812. It remained in the Harrison family until the late 1840s.
The mansion includes the council chamber where Harrison met with representatives from various American Indian tribes. In 1805, Harrison negotiated the Treaty of Grouseland with a number of important Indian leaders, including Little Turtle and Buckongahelas. Harrison had two confrontations with the Shawnee leader Tecumseh at Grouseland in 1810 and 1811 (see Tecumseh's War). Harrison's thirteen treaties with Native American leaders resulted in millions of acres of land being acquired by the United States.
Today, Grouseland is owned by the Daughters of the American Revolution who saved the building from destruction. It is overseen by the Grouseland Foundation, a volunteer board of directors composed of DAR and non-DAR members to manage the structure and programs. The main campus of Vincennes University is adjacent to the property, and other state historic buildings, such as the Territorial Capitol building, have been moved to the property.  It is located in the Vincennes Historic District.
